HALF SUSPENDED JUMPING JACK: Jumping jacks go to a whole new moon-walk level in the pool. Not only do you have to push through the water, but you also have to keep your balance as your natural buoyancy will lead you to tip forward or back. Jump your legs out as you normally would but don't let your feet touch the bottom when you bring them back to the center. Tip: Try a full suspended jumping jack by doing the whole jack without touching the bottom!
