1

Serratus Anterior

Concentrically accelerates scapular protraction

2

Rhomboid Major

Concentrically produces scapular retraction and downward rotation

3

Rhomboid Minor

Concentrically produces scapular retraction and downward rotation

4

Lower traps

Concentrically accelerates scapular depression

5

Middle traps

Concentrically accelerates scapular retraction

6

Upper traps

-Concentrically accelerates cervical extension, lateral flexion, and rotation
-concentrically accelerates scapular elevation

7

Pec Major

[two diff parts-clavicular and sternocostal]
-Concentrically accelerates shoulder flexion (think underhand throw), horizontal adduction (arms raised to front not side), and internal rotation of humerus

*keeps arm attached to trunk of body

8

Pec Minor

Concentrically protracts scapula (aka the wings; scapula attaches humerus and clavicle)

9

Anterior Deltoid

Concentrically accelerates shoulder flexion and internal rotation

10

Medial deltoid

Concentrically accelerates shoulder abduction

11

Posterior deltoid

Concentrically accelerates shoulder extension and external rotation

12

Teres Major

Concentrically accelerates shoulder internal rotation, adduction, and extension
