HOW: Begin by lying on your stomach with your forehead on the ground supported. Place an object like a kettlebell in front of you and to the side you want to perform the exercise with. Bring your arms overhead. From here, lift your arm up and over the kettlebell while continuing to keep them straight. Do this in a slow and controlled motion for the prescribed amount of reps.
FEEL: You should feel your shoulder muscles working.
COMPENSATION: Don’t move your lower body. Make sure to keep your head down.
