Freestyle principle

Freestyle is very rhythmic. It keeps rolling. The power of freestyle comes from these tumbling.

The traditional view is that freestyle produces propulsion under water, that is, the arm forms a certain angle in the water, and then forcibly accelerates the stroke until the end. Then move your arm forward and start the next action again.

The current concept is that freestyle is a bit like walking. Walking is to form a fulcrum first, then move the center of gravity to the front of the fulcrum, then put out another fulcrum, and so on. We don't deliberately set up a support point first, and then move the support point backwards. This is the same as freestyle.

All you have to do is to form a fulcrum in the water, throw an arm forward by rolling, just like walking, move your body in front of the fulcrum, then give up the fulcrum on the basis of establishing another fulcrum, and so on.

This makes simple freestyle movement possible. This action can take advantage of innate forces, such as gravity, torque and energy generated by body rolling.

Freestyle is basically a water sport. As the body rolls, the weight of the arm swings forward and transfers this energy to the fulcrum formed by the arm. So the movement on the water, or the traditional way of moving the arm, is transformed into a kind of free energy that we can use.

Try to keep the weight of your arms in front of your body, and you can control your balance better.
