Some swimmers have a naturally powerful kick, which can help to propel them forward. For the rest, kicking is just a part of keeping afloat. The kick that accompanies freestyle is called the flutter kick and involves moving your legs up and down at the knees. Janek is a firm believer in having a strong kick as part of your freestyle and explained its many benefits.
"Kick is one of the most important aspects of freestyle swimming," Janek says. "In sprinting, it is the key to fast arm turnover, in open water or distance swimming it is a key to a good sustainable tempo. Kick also serves for balance and for assistance with rotation."
Janek explains that freestyle is side to side, instead of flat on the stomach. The kicks helps the hips maintain this efficient side-to-side movement.
"Kick also helps with right body alignment," Janek says. "Without the kick, majority of swimmers' legs would sink as they are not as buoyant as our air-filled lungs. So, by employing a slight travel kick, we keep our body in the right horizontal right below the surface of the water alignment."
