HOW: Start by positioning yourself with your hands on the ground straight down from your shoulders, and your knees on the ground below your hips. Loop a band around your wrist. Push your chest away from the ground as you keep one arm on the ground, the other goes out in different clock numbers for the prescribed amount of reps.
FEEL: You should feel your shoulder muscles working.
COMPENSATION: Don’t slouch your back, keep it straight. Don’t move the rest of your body, only your arm/shoulder.
