HOW: Start by setting up an elevated surface. Put your feet onto the surface with your toes pushing into the surface and your arms on the ground under your shoulders supporting your body in a tall plank position. From here, push into the ground and walk your hands back towards your feet as you push your hips into the air while keeping your knees straight. Walk back out to the starting position and repeat for the prescribed amount of reps. FEEL: You should feel your shoulders and core muscles working. COMPENSATION: Make sure to use your hands and shoulders to help elevate your hips in the air, not your lower body muscles. Exercise Library
