10 major Muscles
Name___________________
1. Gluteals Exercise: _________________________
The gluteals are also known as your glutes or buttocks. They are a large muscle group comprised of the
gluteus maximus, minimus and medius. The gluteus maximus has an origination point of the pelvic crest
and ends at the femur - the long bone located in the thigh portion of your leg. The gluteus medius and
minimus originate at the pelvis and end at the side of your femur. The gluteus maximus allows for hip
extension, the ability to move your leg backwards. The gluteus medius and minimus allow for hip
abduction, allowing you to move your legs away from the center of your body.
2. Latissimus Dorsi Exercise: _________________________
The latissimus dorsi is a large muscle located in your back. These muscles are well-defined and resemble
that of wings. They originate in your lower back and insert into the humerus, the bone in the top portion of
your arm. They allow your arm to rotate. Additionally, the latissimus dorsi allow you to perform a pulling
action.
3. Pectorals Major Exercise: _________________________
The pectorals major is your chest muscle. The pectorals major originates at the sternum- your
breastbone. The insertion point it the humerus. The pectorals major allow for the flexing and adduction of
your arms, helping to bring your arms inward towards your chest.
4. Trapezius Exercise: _________________________
The trapezius is the muscle located in the upper portion of your back and around your neck. The
trapezius originates in your skull and runs down the center of your spine to the last thoracic vertebrae. Its
insertion point is the collar bone, the outer portion of your shoulder bone. The trapezius allows you to
elevate, retract and raise your shoulder blade.
5. Deltoids Exercise: _________________________
The deltoids are your shoulder muscles and are comprised of three different muscles. They include the
anterior deltoids, which is the front of your shoulder allow your arms to move forward. The medial deltoids
are the middle muscles of your shoulders. They are responsible for extending the arms out from the side
of your body. The posterior deltoids are the back of the shoulder muscles. They allow your arms to reach
backwards.
6. Biceps Brachii Exercise: _________________________
Located in your upper arm, the biceps brachii include a short and long head. The short and long head of
your biceps brachii originate at the scapular and have an insertion point of the ulna and radius, the bones
in the lower portion of your arm. They are responsible for flexing the arm as well as decreasing the angle
of your elbow. The biceps brachii also allow you to bring your forearm to your upper arm.
7. Triceps Brachii Exercise: _________________________
The triceps brachii are found on the back of your upper arm. They are comprised of three heads. The
long head begins at the scapula; the lateral head starts at your humerus and the medial head starts at the
bottom portion of your humerus and ends at the olecranon process, your elbow. The triceps brachii give
you the ability to extend and straighten your arm. The triceps brachii also allow you to increase the angel
at your elbow joints.
8. Quadriceps Exercise: _________________________
The quadriceps are made up of four different muscles, which are located at the front portion of your
thighs. These muscles originate at the top of the your femur and end at the shin- or the front portion of
your tibia. They include the rectus femorsis, vastus lateralis, vastus intermedius and vastus medialis.
These four muscles work together in order to allow for knee extension. They also allow the hip to bend.
9. Hamstrings Exercise: _________________________
The hamstrings are comprised of the biceps femoris, semimembranosus and semitendinosus. They are
located on the back of your thigh. The hamstring originate just below the gluteus maximus and insert into
the shin. They allow for the bending of your knee.
10.
Gastrocnemius
The gastrocenmius is frequently referred to as your calf muscle. The calf muscle and located on the back
portion of your lower leg. The gastrocenmius originates behind the knee at your femur and inserts into the
Achilles tendo, the tendon on the heel of your foot. The gastrocnemius allows for plantar flexion elevation
of the heel- while standing on your toes.
