In contrast, Pereira et al. (2010) found that hip adductor muscle activity was increased by increasing hip
external rotation angle (between 0 and 30 degrees), when using the same absolute load for each variation.
For shoulder injuries, rotator cuff work (internal and
external rotation), front, lateral raise, and eventually overhead motions are a great way to strengthen the shoulder at the various
angles it needs to be mobile and strong.
