Simultaneous arms and legs.

Start playing free

  1. The arms and legs alternate left and right
  2. The legs use a dolphin kick
  3. Both arms move together, and both legs move together ✔

Why: In breaststroke, both arms move together and both legs move together. Alternating arm or leg movements, such as a flutter kick, are not allowed.

Huh, didn't know that: One single butterfly kick is allowed after the start and each turn, before the first breaststroke kick.
