1. Elbow and shoulder joints should be at right angles to the body and prone on the floor. Support your weight with your toes and forearms.

2. Bend your arms and put them under your shoulders. Keep your body straight at all times. Keep a good balance and don't rush into it.

3, support to the abdomen, but not collapse. Stay in this position as long as possible. To increase the difficulty, you can lift your arm or leg, and you can lift a foot or hand in the air.
