With many shoulders and acromioclavicular joints being damaged from instabilities in the lats, overuse of the barbell presses, and poor external/internal rotation and stability…what’s left is little space for the joint to move. The half-kneeling Arnold press 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 likely in the range of 7 to 30 reps. It is always wise to switch up volume and intensity based on goals. Hypertrophy must be controlled and mastered before true strength training can be practiced without faults. In every sport, the ability of a joint to move at end range while muscle tissue is contracting is just as important as what our emotional and spiritual intent is in training. Are you training? Or are you scrolling at your phone pretending to train. Take the time to study and execute, this is why I haven’t laid out programming. I want people to do it themselves, its how you obtain the hobby.
