Before explaining the action steps, it must be emphasized that you must do some preparatory activities before each action, especially stretching actions such as bending over to relax the muscles of waist, legs and neck, otherwise you will be easily injured during exercise.

Let's take a look at the decomposition steps of riding a bicycle upside down:

① Sit down, with your legs slightly bent together, your feet flat on the ground, your arms drooping naturally, your back straight, and your eyes looking straight ahead. Be careful not to support the ground with your hands, but to sit up straight with the strength of your back.

② Lie down slowly, with your legs straight, arms at your sides and palms up. Keep breathing evenly and slowly, use the strength of abdominal muscles to slowly lift your legs at 90 degrees to your body, then exhale to contract your abdomen, hold your back with your hands, hold your elbows on the ground, and hold your body upright. Be careful not to support the ground with your arms when you raise your legs to 90 degrees with your body. Keep your legs straight all the way and try to control your center of gravity. When you continue to straighten your back from 90 degrees, you can use your hands to support your back slightly, but be careful not to use too much force or kick your leg backwards, otherwise you will easily turn over and sprain your neck. As long as you keep your back straight and use your hands slightly, your body will naturally stand up.
