Lie down with your chest on the ground, with your elbows bent and your forearms resting on the floor. Your elbows should be underneath with shoulders and hands at eye or nose level.
Push your hands and forearms into the ground, and pretend you're pulling your body away from the floor, until you're in an elbow plank position.
Slowly lower yourself to the starting position with your elbows completely touching the ground. Keep your core supertight to help keep your body moving altogether.
