That's because the muscle strength of the abdomen in the early stage is not strong, and it is easy to drive the neck to exert strength when doing belly roll. It's like doing sit-ups, putting your head in your hands, fixing your legs, and exerting strength on your hands and feet. So sit-ups and abdominal exercises have no effect.

Improved method:

1, when doing abdominal movements, don't put your hands on your neck and head. Even if you do, just touch them gently, don't use force.

2. Try to relax your neck, stretch naturally, and have the initiative to prevent your neck from exerting force.

After practicing for a period of time, the abdominal muscles will have strength, and the force on the neck will be less and less, so there will be no problem of neck pain.

In short, correct your movements, relax your neck and use your abdominal muscles to exert your strength.
