This stroke is performed with your stomach facing down. Your arms move simultaneously beneath the surface of the water in a half circular movement in front of your body. Your legs perform the whip kick at the same time. The whip kick is executed by bringing your legs from straight behind you close to your body by bending both at your knees and at your hips. Your legs then move outward and off to the side before extending and coming back together. This swimming technique is often compared to a frog’s movement.
To execute the freestyle stroke, you lie on your stomach with your body parallel to the water. Propel yourself forward with alternating arm movements in a sort of windmill motion that starts by pushing underwater and recovers above water. Your legs should propel you with a flutter kick, which is performed with pointed feet as your legs move up and down in alternation. Do not bend your legs at the knee.
To perform the backstroke, while floating on your back, alternate your arms with a windmill-like motion to propel yourself backwards. Like the front crawl, your arms should start the circular motion by pushing underwater and recovering above water. Your legs should engage in a flutter kick. Your face should be above the surface as you look straight up
To perform the butterfly stroke, start horizontal with your stomach facing the bottom of the pool. Bring your arms simultaneously over your head and push them into the water to propel you forward and bring them up out of the water again to repeat. As you move your arms into the water, you will push your head and shoulders above the surface of the water.
