Article: The two-beat kick requires less power and is used by long distance and middle distance swimmers. You kick one leg per stroke cycle. One stroke cycle means the stroke of one arm. Kick one leg in conjunction with the insweep of the opposite arm. (The insweep is when the arm starts pulling water toward the midsection of the body.) If you can think about how your arms and legs sync while you are walking, how your arm moves forward at the same time as the opposite leg, you can imagine how your kicking should be synced with your arm stroke in a similar way. The six-beat kick requires that you kick three times per arm stroke cycle. The third beat of the kicking cycle will start during the recovery phase. This is a faster kick that is used by faster swimmers. If your toes aren't pointed while you kick then there will be extra drag caused by your exposed forefoot. Your toes should face inward, and your big toes should come close to touching as you kick. When you point your toes, you are exercising the flexibility in your ankles. If you are having difficulty with ankle flexibility, consider using mid-length flippers to practice your kick. You can focus on both your freestyle arm and leg techniques more easily with the extra propulsion that flippers provide. But only use your flippers to help train your feet during drills.

What is a summary?
Use the two-beat kick. Point your toes while you kick.
