How does studying the anatomy of the major muscles help in physical education subject?
For weight training and conditioning, knowledge of the musculoskeletal system is a must, to target the appropriate muscles and to prevent injury. Knowledge of the cardiovascular/ respiratory system is mostly for cardio workouts, and metabolic physiology and nutrition is also important to maintain health.
Where are the major muscles located in your body?
Major muscles of the back, shoulder and chest:
| Muscle | Origin |

| Latissimus dorsi | Thoracic, lumbar vertebrae, sacrum and top of pelvis |
| Trapezius | Cervical and thoracic vertebrae, base of skull |
| Rhomboids | C7-T5 vertebrae |
| Deltoid | Clavicle and spine of scapula |
What is the main function of the pectoralis major?
The pectoralis major extends across the upper part of the chest and is attached to a ridge at the rear of the humerus (the bone of the upper arm). Its major actions are adduction, or depression, of the arm (in opposition to the action of the deltoideus muscle) and rotation of the arm forward about the axis of the body.
