The abdominal chakra is very exciting to the whole body (especially the front), because almost all the bones of the whole body are supporting it, so this action is difficult to do. Sit-ups only use the spine and hip joint. Weight and torque determine that the stimulation of abdominal muscles and iliopsoas muscles by abdominal wheels is incomparable to sit-ups and leg hanging, and everything depends on personal needs.

The training of abdominal muscles is a systemic compound action, so there are many auxiliary muscles. But the target muscles are rectus abdominis and transverse abdominis. The most important thing is the abdominal muscles, which can also enlarge the pectoral muscles and abdominal muscles, the lower part of the pectoral muscles, infraspinatus of latissimus dorsi, teres minor of teres major and the posterior bundle of deltoid muscles.

Precautions:

1. Lifting the upper body with neck strength and doing sit-ups with your hands on your head may do harm to your spine. In addition, holding your breath will increase the pressure on blood vessels, which may lead to the rupture of the dura blood vessels in the outermost layer of the cervical spine, and the blood clot will compress the nerves and make the whole body paralyzed.

2. Don't hold your breath when you get up, and don't hold your head with your hands when you do sit-ups. In addition, when you get up, you can't hold your breath, which will lead to the rupture of blood vessels and the legs not being straightened correctly, which will increase the burden on your back.

3. Cross your hands on your chest and slowly get up with your abdomen. At the same time, exhale when you get up, don't hold your breath, 1 day can only be done 20 times.
