2. 6 Beat Kick Drills
Use the 6-beat kick to stabilize your lower body.
It makes your swim resistant to a swell or a current.
Constantly moving your legs helps to avoid cramps and maintain body temperature.
The basic concept of the 6-beat kick involves movement of knees.
First practice kicking with both legs together, and then kicking separately.
Finally add movement of the arms.
Work towards a compact kick that helps you swim for a long time.
