5 Tips for a More Effective Freestyle
Relax. 50% of the arm cycle, the entire recovery and glide phase of the stroke, should stay relaxed while the effort is being directed into the underwater pull.
Streamline. Get out of your own way. The speed you are moving when you push off the walls is the fastest you will be moving in the entire length. Don't slow yourself down by lifting your head too soon or taking a big kick.
Roll Hips. Don't rely only on your arm muscles for power. Involve the various muscles that extend down your back and side by driving your hips from side to side each time you extend your arms into the water in front of your head.
Extend. Push back past your hips until your arm is locked at the elbow. Then exit the water by lifting the elbow, keeping the arm and hand relaxed.
Turbo Kick. A small kick is all you need to balance your stroke and maintain a good body position. Want to go faster? Keep the small kick but increase the intensity. Large kicks take too long, take too much energy and produce too much drag.
