Start in a plank position, resting on your elbows and toes, with straight legs and feet together. Make your body as rigid as you can from your feet to your head to keep it in a straight "plank-like" shape side on. Do this by tensing your quads to lift your knee caps up your thighs, squeezing your glutes together, bracing your core and drawing your belly button up away from the floor, whilst at the same time pressing down into the floor with your elbows. From this position bend your right knee and touch it gently on the ground. Straighten your right leg and repeat with the left. Keep your core and glutes engaged at all times with hips level.
