Jumps both legs

It is similar to jumps from one leg to the other. Keep straight, legs straight and strengthened but not convulsively. Do not bounce from toes, but from the whole foot. Do not bend knees. Do circular motion with your arms in front of you. When you are on the ground, the arms are down. While jumping, the arms go up inside. While going down, the arms go down outside. Do not put arms behind the axis of your body. Try to jump on the spot.
