HOW: Begin in plank position with your forearms on the ground, flat back, and your toes pushing into the ground. From here, push into the ground with your forearms lifting your body up. Catch yourself placing your hands on the ground slightly wider than your shoulders in the push up position. Perform a full push up, then return to the starting plank position.
FEEL: You should feel your core, chest, and tricep muscles working.
COMPENSATION: Keep a flat back, don’t let it come up or down.
