| scapula upward rotation | PM serratus anterior; SYN trapezius |
| scapula downward rotation | PM pectoralis minor; SYN levator scapulae |
| scapula retraction | PM rhomboid major; SYN rhomboid minor |
| scapula elevation | PM levator scapulae; SYN trapezius |
| scapula depression | PM trapezius; SYN pectoralis minor |
| contracting the subclavius | stabilizes and depresses the entire shoulder |
| elbow flexion | PM biceps ; SYN pronator teres |
| elbow extension | PM triceps; SYN anconeus |
| elbow pronation | PM pronator teres; SYN pronator quadratus |
| elbow supination | PM none; SYN supinator |
| hip flexion | PM iliopsoas; SYN tensor fascia latae |
| hip extension | PM gluteus maximus SYN semitendonosus |
| hip abduction | PM gluteus medius; SYN gluteus maximus |
| hip adduction | PM none; SYN adductors |

| concentric contraction | muscle shortens (force and movement in same direction) |
| eccentric contraction | muscle lengthens (force and movement in opposite directions) |
| open kinetic chain | freely moving, unfixed to object (dumbbell) |
| closed kinetic chain | restrains movement (barbell) |
| 3 planes | coronal (a/p), sagittal (r/l), transverse (s/i) |
| eccentric is usually | flexion, adduction |
| concentric is usually | extension, abduction |
