There are two variations of the belly twist. Where the legs are bent in version A, they are straightened in version B.
Practicing this twist can help with stress and anxiety. It also reduces fatigue and relieves headaches. It realigns and lengthens the spine, strengthens the lower back, improves digestion and blood circulation, and opens the hips. It even helps with back and neck pain and relieves sciatica.
If it is not possible to hold the foot with the hand, a strap can be used instead.
