If you want fast flutter kickers, dolphin kickers, and underwater kickers, they all need to have snappy feet.
The feet snap through at the end of every kick, which helps swimmers create more propulsion.
But it’s not a conscious movement.

It happens because they have flexible ankles AND because they relax.
They snap the kick down and they do so without a ton of tension through the lower leg.
That allows the whip of the leg to directly influence the ankle, and that means more propulsion.

When you help swimmers kick fast, it’s important to kick hard, and it’s also important to help them learn how to kick fluidly and stay relaxed where it matters most.

The butterfly kick. A visual 🧵.
The kick plays three key roles in helping butterflyers go fast.
1. It helps them create propulsion. The kick can power swimmers down the pool, and the more propulsion they create, the faster they go.
