WEIGHT ROOM UNIT Safety Always warm-up Avoid lifting too much weight Use spotters Breath during exercise Rack weights after use Definition of Terms Strength – the ability to exert during a single effort Repetition – moving a weight through a full range of motion one time Set – a group of repetitions Maximum – the most weight an individual can lift one time Range of Motion (R.O.M) – The distance a muscle or joint on the body may move, from completely extended to completely flexed Atrophy – a decrease in muscle size Hypertrophy – an increase in muscle size Spotting – the physical act of assisting in the safety of a lifter, while s/he is lifting Press – an exercise in which the weight is moved away from the body Curl – an exercise in which the weight is moved towards the body or when a joint of t he body is closed Extension – the opened phase of a body joint Flexion – the closed phase of a body joint High Intensity Training (H.I.T.) – performing one set of 8 to 12 repetitions until you reach muscle fatigue Absolute Strength- maximum force a muscle can generate in one effort Dynamic Strength- the ability of a muscle to contract over time Specificity- involves selecting the right exercise to develop each muscle Overload-applying resistance to a muscle that is greater than a muscle is used to handling Muscle Strength Theory Muscle is made up of 75% water and 25% protein. Muscles are made up of bundled fibers – muscle fibers can grow bigger but you cannot grow more muscle fibers. The more you work out the more muscle fibers you body will use Types of Weight Lifting Programs 1. 2. 3. 4. Endurance – the lifter will do 3-4 sets with 12-15 repetitions at 60-70% of max. Tone – the lifter will do 3 sets of 8-10 repetitions at 70-75% of max Bulk – the lifter will do 3-4 sets at low repetitions at 80-85% of max H.I.T. – lifter will do one set of at least 8 reps but no more than 12 reps Things to remember Select exercises that work a wide range of muscle groups Sequence exercises from large muscle groups to small groups Sequence exercises to balance the muscles (work opposing muscle groups - ex. Triceps, bicecps or Quads, Hamstrings) Remember to stretch before and after your workout Use proper exercise speed – approximately 1 second to complete 90 degrees of joint motion Always, always complete full R.O.M. Breath comfortably during the entire exercise During the exercise move from extension to flexion Isolate the prime mover – use only the muscle you are working Stabilize the joint position so the prime mover is muscle most involved Basic Lift Muscles Developed 1.
