With many shoulders and acromioclavicular joints being damaged from instabilities in the lats—and overuse of the barbell presses, here is a rotational press to program in between your heavy barbell work. The split stance incorporates core stability while the rotation challenges stability of the shoulder. Try 4-6 reps for 2-3 sets. Remember true strength is lower rep counts. Hypertrophy is more 7-30 reps. Pick your poison.
