Kneeling for belly roll training! It is the same as ordinary supine belly roll, but the position is different and the action principle is the same!
Kneeling and belly rolling are very popular in the gym. The advantage is that you can use roller skating to increase weight, and it is safe and convenient! But not many people can do it well!
Most people kneel and roll their bellies as follows:
In fact, this action uses too much hip strength, which leads to the stimulation of abdominal muscles is not in place!
When the spine contracts centripetally, this action uses the function of rectus abdominis to bend the spine. In the above demonstration, the posture of leaning over has become a lot of hip flexion, which leads to too much participation of hip flexion muscles (iliopsoas and rectus femoris)! Abdominal muscles have little effect!
The correct demonstration is as follows:
1. Fix the hip joint, and don't let the hip joint participate in sports!
2. The contraction of abdominal muscles makes the spine bend slowly. Imagine your chin touching the lower part of your abdomen. Finally, the rectus abdominis completely contracted!
3. Actions should be carried out in an orderly manner, slowly, and don't rely on inertia!
