It is no coincidence that the best freestyle (front crawl) swimmers across the world have an amazingly strong, powerful leg kick.
As much as the freestyle stroke is predominately powered by the arms and upper body, and only relies on the leg kick for a small amount of overall forward propulsion (around 10 to 15% and even less for novice and weaker swimmers), without a strong leg kick, you are at a disadvantage. The perfect freestyle kick can generate better balance, drive body rotation and lift the whole body higher in the water. Triathletes generally aim to kick less in their freestyle swimming stroke but without any kick, the body position is affected and as the legs can drop. To swim faster, you need to put the leg work in during your swim training and also develop leg strength in the gym.
