START ROLLING When you are directly above the T on the bottom of the pool, begin your half-somersault. Tuck your chin, kick one last hard kick and finish your arm pull with your hands ending at your sides. Note: For a first timer, you may want to plug your nose with either a nose plug or your hand during this exercise. No one likes getting tons of water up their nose! However, once you've mastered this step, try blowing bubbles out your nose instead of plugging it with your hand. Having both hands free makes a flip turn much easier to complete.
