How to do Plank Crunch And Kickback (Left)

Instructions

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.

Pull your left knee up and into your chest, then straighten your left leg and raise it up toward the ceiling. Swing it back down, pulling your left knee into your chest again to repeat.
