Your external rotators need more than one angle.
Side-lying external rotation is a solid start.
But the rotator cuff does not work in one position only.
Change the position of the humerus — arm by the side, arm in front, arm at 90° abduction — and you change the stimulus, the range, and the demand on the posterior cuff.
Underused. Precise. Useful.
