1 Weight Training 101 Weight Training Design Terms Training with improper form and technique can lead to injury and keep you from reaching your goals. Understanding how to lift weights correctly and how to structure a workout program will lead to increased fitness and performance. Always think safety first—don’t lift too heavy and use spotters as appropriate. Lift through full range of motion—and control the weight—do not use momentum to help you lift the weight—it is too heavy if you cannot keep proper form Atrophy a reduction in the size of a muscle, usually due to a lack of muscular activity Hypertrophy an increase in the size and cross-sectional area of a muscle—“bulking up” One rep max the greatest amount of weight that can be lifted with proper technique for only one repetition Set The number of repetitions performed consecutively without resting—a fixed number of reps Repetition Range A range of repetitions that are to be performed maximally during one set 2 The Active Life Sedentary Lifestyle Chronic Diseases Physical Fitness Aerobic Exercise Anaerobic Exercise a pattern of living where a person engages in little physical activity. It is a risk factor for a number of chronic diseases. illnesses that develop as a result of an unhealthy lifestyle and last a long time. Examples include: heart disease, cancer, stroke, obesity, and diabetes. the ability to perform daily living tasks and not experience undue fatigue. Having enough strength, energy, and stamina left over to enjoy recreational pursuits and be able to meet unforeseen emergencies. exercise during which the muscle cells receive enough oxygen to continue at a steady state. Some examples are running, swimming, and biking. exercise during which the energy needed is provided without oxygen. Some examples include sprinting and weight-lifting. Living a sedentary lifestyle is an almost guaranteed path to disease and premature death. Participating in regular physical activity and exercise improves your physical fitness as well as other aspects of your health. The Center for Disease Control (CDC) recommends that individuals acquire a certain amount of activity to receive health benefits. On a daily basis individuals should aim to get 60 minutes of physical activity. On a weekly basis an individual should get: Aerobic Activity Resistance Training 150 minutes moderate-intensity activity or Do muscle-strengthening activities on 2 or more days a week that work all major muscle groups 75 minutes of vigorous-intensity activity 3 Physical Activity and Exercise Physical activity refers to all bodily movements that cause increases in physical exertion beyond that which occurs during normal activities of daily living. Physical activity is any bodily movement that results in the burning of calories. Being physically active is the opposite of living a sedentary lifestyle: which means having a life of very little movement. Exercise is planned, structured, and repetitive physical activity designed to improve or maintain fitness. Exercise is a form of chosen physical activity as opposed to physical activity that is done at a job (i.e., lifting boxes, walking around hallways, etc.) or in household chores (i.e., sweeping, gardening, etc.) that is undertaken in order to achieve a particular goal, such as improved appearance, improved cardiovascular fitness or greater muscular strength. Exercise is intentionally choosing a specific activity to help you reach an objective. All exercise is physical activity, but not all physical activity is exercise! The Benefits of Physical Activity & Exercise Benefits of Regularly Participating in Cardiorespiratory Fitness Training Physical Benefits: Lowers resting heart rate and blood pressure-reduces the risk for cardiovascular disease Helps to burn fat and control body weight. Increases lung capacity Helps improve sleep patterns Mental Benefits: Improves regulation of stress hormones (feel less stressed) Improves blood flow to the brain, allowing a person to be able to think faster—improving memory and attention span Improves mood—reduces the risk of depression Benefits of Regularly Participating in Resistance Training Builds and tones muscles—helps with functional fitness (being able to lift & carry things) Increases the strength and density of bones (less likely to get fractures and osteoporosis) Increases muscle mass—which helps to maintain a healthy metabolism (leads to greater fat loss) Reduces chances for muscle deterioration later in life and less chance of muscle injury Helps control blood sugar levels—reduces risk for diabetes Improved sport performance Improved resistance to fatigue Fitness is an asset. You are better at everything you do the more fit you are—even academics. It has been found that students with higher levels of aerobic fitness have better attention spans, better memories, and perform better on tests. Athletes train to improve sport performance, but everyone needs to train to perform activities of daily life such as carrying objects (trays of food, children, boxes) and transportation (walking to school, climbing stairs, biking to work). In summary, regular physical activity and exercise can improve your current quality of life by improving your ability to do daily activities and increasing your energy levels. Consistently following a prescribed fitness program can increase your chances of living longer by reducing risks for various diseases, as well as reduce potential medical costs associated with chronic diseases. 4 Health-Related Fitness Physical fitness is made up of various components that can be classified into two categories: health-related and skill-related components. The five health-related components of fitness listed below relate to how well your body systems operate, such as your circulatory system, muscular system, and respiratory system. Meeting healthy fitness standards for each of these components decreases your risk for developing chronic diseases and also reduces the incidence of musculoskeletal injuries, such as low back pain and muscle strains. Body Composition Flexibility the ratio of body fat to all other body tissue ( including muscle, bone, water, and connective tissue). Expressed as a %, such as 17% body fat. the ability of a joint to move through its available range of motion. Cardiorespiratory endurance the ability of the heart, lungs, and blood vessels to use and send fuel and oxygen to the body’s tissues during long periods of moderate-to-vigorous activity Muscular strength the ability to exert maximum force against a resistance during a single effort. Muscular endurance the ability of the muscles to perform physical tasks repeatedly with moderate loads for an extended period of time before muscular fatigue occurs. To meet healthy fitness standards for each of these components throughout your life it is important to follow a specific training and conditioning program as well as follow a balanced nutritional plan designed for your needs. The FITT principle can help you to design an appropriate workout plan to be sure that you are getting adequate amounts of exercise. The FITT Principle of Training Think of the FITT principle as a set of rules to follow in order to benefit from a fitness training program. The FITT Principle provides a framework for developing a balanced program that targets the health-related components of fitness. This framework allows you to design a workout that can help you to promote and maintain your health by reducing your risk for various lifestyle diseases, such as heart disease, cancer, stroke, and diabetes. F: Frequency is the number of times you exercise each week. I: Intensity is how hard you are working while you are exercising. T: Time is the total amount of time that is spent exercising in one session. T: Type is the type of exercise you are doing. When designing your workouts, you should keep each of these components in mind for flexibility, cardiorespiratory fitness, and muscular strength/endurance. 5 The FITT Principle of Training Flexibility Training Frequency Can be done daily. Stretching as necessary before and after a workout. Focus on improving flexibility by conducting a stretching routine at least 2 times a week. Intensity Stretching that increases range of motion. Trying to stretch farther than before. Time Spend at least 20-30 seconds on each stretch. Try to do at least 5 minutes daily. Type Uses all major muscle groups allowing the body parts to move through the full range of motion. Example: yoga Training for Cardiorespiratory Endurance Frequency A workout schedule of activity 3-5 times a week. Frequency depends upon intensity. Intensity Your heart rate is the primary measure of intensity, and your target heart rate zone (60-85% MHR) is what you should aim for when training for cardiorespiratory endurance. For the 15-18 year old range, the target heart rate zone is about 121 -175 bpm. Time Depends upon intensity: 20 minutes if vigorous intensity (3 times a week) or 30 minutes if moderate intensity (5 times a week). A goal should be to workout within your target heart rate zone for a minimum of 20-30 minutes if best. Type Any exercise that allows me to keep my heart rate in the target zone, such as running, swimming, or biking for the recommended time. Training for Muscular Endurance Frequency A workout schedule that includes 2-6 days a weeks. (Frequency depends upon the time and structure of the routine and how many muscle groups you are exercising each day) You should work out at least 2 different days in the week and give each muscle group a 48 hour rest in between sessions—especially if you are lifting heavy. Intensity Each muscle group needs to be worked at least 8 or more reps twice a week. Increase the number of repetitions for body resistance exercises such as push-ups or increase the weight if you can do more than 20 repetitions with that weight. Intensity is adjusted by increasing or decreasing the weight lifted, the repetitions performed, and rest between sets. Time Typically 20-60 minutes to include different muscle groups. Time depends upon frequency—if you are lifting more days a week you may decrease the time, if you are lifting fewer days a week, you may need to increase the time of a session. Type Do resistance training activities that work all major muscle groups (8-10 different exercises minimum). Examples: Weight-lifting or body resistance (push-ups, sit-ups). 6 Warm-Up and Cool-Down Before participating in a cardiorespiratory or resistance training workout, one should perform a proper warm-up routine. The purpose of warming up is to prepare the body for exercise by directing blood flow to the targeted muscles. Increased blood flow raises body/muscle temperature which improves muscle elasticity. This can help to prevent injury by improving the flexibility of the muscles. More blood flow also means more oxygen to the muscles so that they are able to work longer. This improves workout performance and efficiency because the muscles are “primed” with blood and the nerve receptors are prepared to fire. Your body is more like a tea kettle than a light switch—you can’t turn your energy systems on and off automatically—they need time to adjust to the effort and warming-up helps your body prepare to exert more energy. A warm-up routine typically begins with a total body activity designed to increase blood flow to all muscles, such as a slow jog, jumping rope, or jumping jacks. This part of the warm-up should last approximately two to five minutes or until a sweat begins to appear. After this, individuals can perform specific dynamic activities designed to stretch the muscles and ligaments that will be used during the workout. These activities should be movements and skills that the individual will be engaging in, such as doing push-ups before performing the bench press, lunges before a volleyball game, or defensive slides before a basketball game. The reason that stretching follows the total body activity in the warm-up routine is that warm muscles can be stretched farther and are less likely to be injured. Cold muscles do not have the elasticity to improve range of motion and forcing the stretch can result in a strain. At the completion of a vigorous cardiovascular workout, participants should gradually slow the heart rate to a steady state to prevent blood from pooling in the muscles that have been used. If exercise is abruptly halted, blood may pool in the muscles and the heart will have to work harder to keep the blood circulating. This may result in dizziness and fainting. Also, doing a cool-down helps with the removal of lactic acid from the muscles so that you are less likely to be stiff and sore the next day. Post-workout stretching restores the muscles to their resting length, stimulating blood flow, and reducing muscle spasms. This will decrease stiffness and soreness and help to improve flexibility and range of motion (ROM). Having an elevated core temperature is important before conducting static stretching as it lowers muscle tension, reducing the risk for stretching injuries. Improving ROM in your joints helps to improve performance and prevent injury. The skeletal muscles of the body will shorten over time as a result of poor posture and lack of activity. Proper stretching works to restore the flexibility of a joint by elongating the muscles surrounding the joint. 7 Cardiorespiratory Fitness Terms Stroke Volume Amount of blood pumped by the heart in one beat Cardiac Output Amount of blood pumped by the heart in one minute (bpm = beats per minute) Target Heart Rate Zone The recommended training intensity range (stated in exercise heart rate bpm) to obtain adequate cardiorespiratory endurance. Maximum Heart Rate (MHR) Highest heart rate for a person, related primarily to age. Resting Heart Rate (RHR): the number of times your heart beats per minute while at rest. Make sure you have been at rest for at least 30 min before taking your RHR, then compare to the chart below: Excellent (elite athlete) Below 50 bpm A well-conditioned athlete Around 60 bpm Men 60-80 bpm Average resting heart rate Women 70-90 bpm Finding Your Target Heart Rate Zone Sedentary (poor fitness) Over 100 bpm A simple way to determine your target heart rate range is to use the following formula. An example for a 15 year old person would be as follows: 1. 220 - age = Maximum Heart Rate (MHR) 220 – 15 = 205 is MHR 2. Then multiply your MHR by 60% and 85% to find your target heart rate range: 3. 205 x .60 = 123 and 205 x . 85 = 174 Target Heart Rate Zone= 123 – 174 8 Cardiorespiratory Fitness Training The main goal of cardiorespiratory training is to make your heart a more efficient pump. It becomes more efficient by increasing the stroke volume--which means it pumps more blood with each bump. Since each beat has more blood, the heart doesn’t have to pump as fast to distribute blood throughout the body. This results in a lower resting heart rate and decreases the workload of the heart. In order for these physiological changes to occur, you must train at an intensity that “overloads” the heart. That intensity can be determined by finding your target heart rate zone. Resting heart rates can decrease by 10-20 bpm after 6-8 weeks of consistent training. A reduction of 20 bpm saves the heart about 10,483,200 beats per year. Cardiorespiratory Training Levels Intensity Level & Description Approximate Heart Rate Range for 15-19 yrs Examples of Training Maximum Effort Over 85%--going all out, can only do this for a short period of time 173-206 bpm Interval Training:1 min Sprints, 2 min walk. Repeat 6-7 times = about 20 min vigorous Vigorous 66-85% MHR—Breaking a sweat, hard to talk while exercising because you are breathing so hard 133-173 bpm Running the mile at your fastest pace possible Moderate 50-65% MHR—Breaking a sweat and talking requires some effort— can’t carry a conversation, but can talk 103-133 bpm Jogging 2 miles at a steady pace— maybe combining walking and jogging if you can’t walk the whole way Easy 40-50% MHR-Can carry on a conversation—easy pace that could maintain all day 80-103 bpm Walking 1-2 miles No Effort Sedentary-- Sitting Below 80 Cardiorespiratory Fitness Training Tips For beginners a target heart rate zone of 50-70 percent of their maximum of heart rate is a good place to start. Individuals with lower fitness levels can start out with 10 minute bouts of exercise and then gradually work their way up. A goal should be to workout within your target heart rate zone for a minimum of 20-30 minutes if best. For fitter, more advanced individuals, a target heart rate zone of 70-85 percent of their maximum of heart rate may be more appropriate. Use interval training to help you improve on being able to run longer. 9 Training and Conditioning There are a variety of ways to train in order to reach your goals. Below are examples of different types of training and conditioning programs that you can use to structure your workouts to achieve the best results. Resistance Training any method or form of exercise that requires a person to exert force against resistance (such as body weight—push-ups, or weights—bench press, or resistance band—bicep curls). This type of training is used primarily to improve muscular strength and endurance. Interval Training a training system that involves vigorous bursts of exercise followed by a recovery period. For example: sprinting 100m and then walking 200m and then sprinting 100m and walking 200m continuously. This type of training is used primarily to improve cardiorespiratory fitness through anaerobic exercise. Can be used to improve speed and explosiveness. Circuit Training a form of conditioning that involves alternating exercises with a fixed workload or time and then a short rest period before starting the next exercise. Typically, you will alternate working different muscle groups. For example: do 20 push-ups, do 20 sit-ups, do 20 air-squats, do 20 jumping jacks and then repeat the circuit. Or do the same exercises for 30 seconds and then rotate. This type of training can be used to improve muscular endurance and cardiorespiratory fitness. Plyometric Training Aerobic Conditioning a form of exercise that requires forceful jumps or springing off the ground immediately after landing from a previous jump. Examples include box jumps, clap push-ups, & tuck jumps. This type of training is used primarily to improve explosiveness and speed. the process of training in order to improve the capacity of the heart and lungs to deliver fuel and oxygen to body tissues. Examples include swimming, biking, and running. This conditioning involves training within your target heart rate zone. This type of training is used primarily to improve cardiorespiratory fitness. Regardless of what type of training program that you choose, it is necessary to include the principles of training in your workout design. Specificity, overload, and progression are the three main principles of training that need to be considered in every workout in order to improve fitness as well as reduce the risk for injury Specificity principle a rule of exercise that states that gains result from training are specific to the type of stress imposed upon the body systems Overload principle a rule of exercise that states that in order to improve the level of fitness, one must progressively increase the workload that the body is accustomed to in order for adaptations to occur. Progression principle gradually increasing a load (intensity) over time to bring about desired improvements 10 The Principle of Overload: In order for you to increase muscular strength or endurance, you must put a greater than normal stress or load on the body in order for it to adapt to greater workloads. For example, you will never become stronger if you only lift 3 sets of 10 at 100 lbs. Eventually, you will have to increase the weight and do a different number of repetitions in order for your body to adapt—which means build the strength for you to lift more—such as lift 115 lbs 10 times. Your muscles adjust to the stress that you put on them, so once your muscles have adjusted to a certain weight—it is no longer considered an overload and you will have to increase the weight to build more strength or increase the repetitions to build more endurance. Your heart muscle is the same way— you must gradually increase the workload (intensity) of your aerobic exercises in order for your heart to become stronger and pump blood more efficiently. One way to increase the intensity of your aerobic workouts is through interval training. The Principle of Progression: Gradually and systematically overloading the body over a period of time will result in improvements in fitness without risk of injury. Trying to increase the intensity too quickly may result in injury and increasing the workload too slowly will most likely not lead to adequate improvements in fitness. Progression implies that you need adequate rest time in order for your muscles to recover. Training too hard and too frequently may result in a condition known as overtraining and a decrease in fitness. The following are general rules regarding progression: increase repetitions or sets before increasing resistance; decrease repetitions when increasing resistance or sets; and decrease the rest interval between sets to increase the workload for muscular endurance. The Principle of Specificity: This principle states that fitness improvements are specific to the type of stress put on the body. There are two different aspects of specificity that individuals need to be aware of. First, it means that the muscle you want to strengthen must be exercised specifically. For example, to train your bicep muscles you need to do exercises that work the biceps—you can’t expect to get bigger biceps doing push-ups. Second, the muscle must be exercised specifically for the goal that you have in mind, such as strength, size, or endurance. Individuals need to choose their weight, sets, and reps specific to the goal that they want to achieve. Their goal (strength, endurance, weight loss, etc.) should be what determines the specific training regimen to follow in order to get desired results. An individual who wants to build muscle mass will be doing a different amount of sets and reps than someone who wants to increase muscular endurance. Also, athletes training for a sport will want to choose lifts that are tailored to movements that they perform. By not following the principles of training you risk injury and decreased performance. Below are some of the consequences of that may result from improper training: Plateau reaching a point of not being able to improve your fitness-- a time when progress stops; indicates that some aspect of the program should be changed to stimulate the desired change. Overtraining a condition that results from excessive physical training. Symptoms include increased fatigue, decreased performance, persistent muscle soreness, mood disturbances, and feelings of “burned out”. Regression if training stops then less stress is placed on the muscles and they atrophy or weaken. Basically losing any strength or fitness improvements that you have made. “Use it or lose it.” Repetitive Is an injury that may result from repetitive use of a certain part of the body—it typically is caused by stress injury overusing certain muscles and joints and not allowing enough rest 11 Weight Training Design: Types of Lifts Power lifts are exercises that are performed very quickly or explosively. These lifts are the most affected by fatigue and should be performed first in a routine due to the level of concentration and skill. Examples: Snatch, hang clean, power clean, push jerk Core lifts (complex or compound lifts) recruit one or more large muscle areas (i.e. pectoralis, quads, lats, glutes) and involve two or more primary joints Examples: Squat, Deadlift, Lunges, Bench press, Standing Military (overhead) press, Core lifts should be at the center or “core” of any workout designed to improve strength and power. In your program design—it is recommended that you perform core lifts before assistance lifts to reduce potential muscular fatigue. If you are not performing power lifts, then core lifts should be the first lift you perform. Assistance lifts (auxiliary or isolation lifts) isolate smaller muscle areas (i.e. biceps, triceps, and calves) and involve only one joint. Examples: biceps curls, calf raises, triceps extension, leg extension, seated hamstring curl Assistance lifts contribute to improving strength and power indirectly by strengthening muscles that assist in core lifts. They also can be used when an injury prevents a person from doing a core lift. For example, if a knee injury prevents a person from doing squats, he can perform the leg extension and leg curl. Core lifts are not to be confused with core strength training. Core strength training exercises are designed to strengthen the abdominals, hip muscles, and muscles surrounding the spine (upper and lower back muscles)—these muscles are referred to as the core of the body. These muscles are responsible for maintaining the stability of the spine and pelvis. Core strength contributes to better posture, balance, and decreases the incidence of lower back pain. Examples of core exercises include: abdominal crunch, bridge, back extensions, superman, lat pull-down, seated row, and curl-ups. Safety Note: Some power lifters may find it beneficial to wear a weight training belt when lifting heavy weight for lifts such as the squat, power clean, and deadlift. The major benefit to wearing a belt is that it can help to stabilize the lower back muscles, preventing injury. On the flip side, those who train with a belt may not get the benefits of strengthening the lower back during exercises. Wearing a belt is a personal choice that should be considered when it comes to injury prevention in heavy lifting. 12 Weight Training Design: Choosing Your Lifts In designing your weight training program, pay attention to what muscle groups you are working with each exercise. You don’t want to write a workout plan that only works biceps and shoulders while neglecting the rest of the muscle groups. Nearly every exercise you perform uses multiple muscle groups. However, certain lifts require more exertion from a specific muscle group. Some lifts emphasize a particular muscle group more, while other muscles assist to support the primary muscle group when performing the actual exercise. For example, when performing the, bench press, the primary muscle worked is the pectoralis or chest muscle and the secondary muscles are the triceps, deltoids, and forearms. You cannot lift the bar without the secondary muscles assisting in the lift, but the bench targets the chest muscle more than the other muscle groups—so it is referred to as a chest exercise. Exercise Primary Secondary (Assisting) Bench Press Pectoralis (Chest) Triceps, Deltoids, Forearms Back Squats Quadriceps, Glutes Hamstrings Upright Rows Trapezius Deltoids, Biceps Lat Pulldown Latissimus Dorsi, Trapezius Posterior deltoids, Biceps Shoulder Press Machine Front & Middle Deltoids Trapezius Modified Pull-Up Latissimus Dorsi, Trapezius Posterior deltoids, Biceps Barbell Curls Biceps Forearms Lateral Shoulder Raise Middle deltoid Leg Extension Quadriceps While each of the assisting muscles are exercised during the lift, they must also be exercised as a primary muscle group. For example, you cannot use the lat pulldown as a bicep exercise since the work of the biceps is minimal in that lift. 13 Weight Training Design: Choosing Your Lifts You may have the option of choosing between free weights and machine weights in your exercise program, so it is important to understand the advantages and disadvantages of each in deciding what ones to pick. Free Weights Weight Machines are weights such as dumbbells, barbells, and plates and can be moved in a number of different way are stationary mechanical devices that move weights using a system of cables and pulleys. Pros Pros allow for a variety of different exercises to be performed with the same equipment do not require a spotter and are less likely to cause injury because less balance is involved. improve coordination and balance since they require the use of many muscles at the same time can decrease the time of your lifting since there is no spotter, you can workout alone, and you don't have to constantly change the plates. better transfer of muscular strength to everyday life as movements are more functional don't take up as much space as some machine weights and can easily be moved from place to place. require greater balance and are more prone to cause accidents due to improper technique. it can take longer to learn the technique of the lifts due to their complicated movements. also requires a spotter may increase the time of your lifting if you have to constantly change plates on the barbell isolates single muscles so can be used for individuals with injuries or disabilities Cons Cons much easier to learn the technique only allow for specific movements--so less exercises can be performed with machines. typically are large, heavy pieces of equipment that are difficult to move may not be able to see as much of a strength gain since spotters cannot assist with reps strength may not transfer to functional fitness improvement since movements are often isolated 14 Weight Training Design: Structuring Your Workout There are a number of different ways that you can structure a weight training workout. Examples include: Circuit Training PushPull Training Split Routine A workout in which you perform a set of several different strength exercises, one right after the other with little or not rest in between the sets. Alternate lifts so that you are not training the same muscle back to back. Example: arm exercise, leg exercise, ab exercise and then repeat the cycle doing a different arm, leg and ab exercise the next time. You could get every muscle group in one day with this workout. There is minimal rest in between the stations so a resistance training circuit could become an aerobic workout. A push–pull workout is a method of arranging a weight training routine so that exercises alternate between push motions and pull motions. Another push–pull technique is to arrange workout routines so that one day involves only push exercises, and an alternate day only pull exercises. Training different muscle groups on different days. For example: upper body on Mon/Thurs, lower body on Tues/Fri, core workouts on Wed/Sat. Group exercises together so that you get adequate rest for each muscle group. One way to design a workout plan to help you achieve muscular balance is to structure your workout in a push-pull routine so that you are exercising opposing muscle groups. Opposing or antagonist muscles are the muscles that do the opposite of the working muscle. So when the biceps are flexing or contracting, the triceps (the antagonist) are extending. If you only focus on working one muscle group and don’t train the opposing muscle group, you may put yourself at risk for injury from muscular imbalances. For example, if you only work your quads and not your hamstrings, that muscular imbalance may result in weak knees and lead to a knee injury. A good tip is to work the opposing muscle between sets of the main muscle that was just worked. For example, after you do a set of biceps—do a set of triceps and then go back and do another set of biceps. You do not need to sit down and do nothing as a rest in between your sets. Your “rest” can be working an opposing muscle group. This saves you time and allows you to get through a workout faster or to be able to do more lifts in a shorter period of time. Location Upper Arm Upper Torso Working Muscle Opposing Muscle Group Triceps Biceps Push Exercises: Dips, Rope Pushdown Pull Exercises: Bicep Curls, Chin-Ups Chest (Pectorals) Latissimus Dorsi Push Exercises: Bench Press, Push-Ups Pull Exercises: Pull-Ups, Lat Pulldown, Seated Row Quadriceps Hamstrings Push Exercises: Leg Extensions, Squats, Leg Press Pull Exercises: Leg Curls, Deadlifts, Good Mornings Abdominals Lower Back Sit-Ups Back Extensions Legs Core 15 Weight Training Design: Picking the Approriate Weight 1. First, you need to decide on your goal, your goal will determine your rep range. The four most basic goals that require different training loads are improved muscular strength, increasing muscle size, improved muscular endurance, and general fitness and toning. 2. Second, identify your sets and reps based upon the recommended range. When looking at the ranges, if you are doing more sets, you would do less reps and if you are doing fewer sets, you would do more reps. 3. Pick a weight that is a challenge, but is not so heavy that you lose form. For example, if your goal is to complete 15 reps, you want to be able to pick a weight that on the 15th time it should be fairly difficult to complete—you really have to struggle to get the last rep. If your goal is to build strength, on the exercises you have a spotter—you may need minimal assistance with the last 1-2 reps of your lifting. For a core lift, such as bench press or squat, you can use your one rep max to help you identify the appropriate weight to lift. For other lifts, you will use trial and error to find the right amount of weight to lift for the recommended repetitions. (Or you can use an estimation chart to determine your find one rep max for auxiliary lifts.) If you cannot keep the right form throughout all of your reps—that weight is too heavy for you. Maintaining proper technique is more important that doing more reps with improper form. Choose Your Sets and Reps Based Upon Your Goal GOAL # of Sets Repetition Range 3-6 6-12 Heavy 70-80% 30-90 Seconds moderate reps Moderate weight short to moderate rest periods 1-6 Very Heavy 70-100% 2-5 Minutes few repetitions High weight full recovery periods 12-25 Light <70% 20-30 Seconds High reps Light weight Short recovery time 8-12 60-80% Moderate reps Moderate weight Hypertrophy Strength Weight % of 1 RM Rest between Sets 3-6 Muscular Endurance 2-3 Fitness & Toning 1-3 30-90 Seconds short to moderate rest periods Remember: The weight that you lift depends on how many repetitions that you are doing. You find your correct weight by finding the weight that is very difficult to do the rep above what you are assigned. 16
