Air pedaling ~ mainly exercises abdominal muscles
Lie on your back on the bed or the floor, with your knees bent, your calves parallel to the ground, and your hands crossed behind your head.
The navel position contracts inward during the entire movement.
Then pull the left knee toward the chest, stand up as much as possible, and lean the right elbow toward the left knee. Without pausing, lower your left leg and bend your right knee at the same time, touching your right knee with your left elbow.
This completes one action, so you can rest after completing one set in a row. Keep your breathing rhythm steady during the movement.
