Swimming is a full-body movement, and efficiency comes from developing coordination between your upper and lower body. The kick provides stability, improved body position and propulsion, all components necessary for a more efficient freestyle.
In the water, over distance it is our arms that generate most movement providing approximately 85% of forward drive and the legs merely serve to 'balance' our position, preventing the body from rotating to far around and stopping our legs from sinking heavily “behind” us.
Notice in the left hand images below how the legs are creating drag by being outside the streamlined profile of the body.
With stroke correction drills to work and isolate the legs we can correct this over time and create a more streamlined body position as in the right hand images.
Perfect your freestyle/front crawl kick and improve your streamlined position. The kick should be generated from your hips, with the power transferring from your hips, through your knee and flex your ankle as your foot flicks down.
