How do you stretch the subscapularis
-external rotation with arm adducted by the side
How do you stretch the deltoid
-extreme horizontal abduction and extension (anterior and middle) -extreme horizontal adduction (posterior)
What actions is the corachobrachialis responsible for
-flexion -adduction -horizontal adduction
What kind of motion does a dumbbell reverse fly execute
-horizontal abduction
