Today's Edge : Avoid sagging on your 1-arm bent over row work. It's easy to be focused on the arm doing the row while you ignore the stabilizing arm. Sagging or hanging on the stabilizing shoulder forfeits your chance to target the small muscles around the shoulder blade. The small shoulder stabilizers on the stationary arm can benefit greatly from this exercise when done correctly.
COACHING KEYS : My favorite cues here are to "push the bench into the floor" or "push your chest away from the floor." This will help you to avoid sagging on the stabilizing shoulder while you engage the small but important shoulder support muscles.
