In-situ jumping is a simple aerobic exercise, which can exercise cardiopulmonary function and lower limb muscles. Here are some action essentials for jumping in place:

1. The body is upright, the feet are shoulder width apart, and the arms naturally droop at the sides of the body. This is the starting position of the action.

2. Bend one leg and lift your foot to knee height. The ipsilateral arm swings backward and the contralateral arm swings forward. The other leg is slightly bent, the foot stays on the ground, and the weight is concentrated on the toes.

3. Then, put down the raised foot and put down the ipsilateral arm. The other leg is slightly bent, the foot stays on the ground, and the weight is concentrated on the toes.

4. Repeat the above steps.
