Exercise abdominal muscles, that is, tear the muscles, then the muscles recombine, harden and burn excess fat, and then there will be six to eight abdominal muscles.

For most people, doing sit-ups is not the right posture, which will lead to certain injuries, especially the spine.

When doing sit-ups, push your abdomen, rely on your abdominal muscles, and don't use your back or ass.

When doing sit-ups, don't do them on hard ground. It's best to do it on a yoga mat. Don't put your hands behind your head. Put your hands next to your ears or temples. Then bend the upper body with abdominal muscles.

Hips don't need to leave the ground, and they don't need to use force, and legs don't need to use force. Hips and legs only have a fixed support function. In this case, there are generally 20 groups, and each group has a rest for one minute. Limited to 5 groups.

The number can increase with the pain of abdominal muscle tearing.

So don't panic,

No matter what exercise you do, you need to move your joints, which can reduce joint friction damage.
