There are two versions of the belly twist. In version A, the knees are bent. In version B, the body twists with straight legs. The twist improves digestion and blood circulation, releases toxins and hydrates the spinal discs. It can also help to relieve stress and mild headaches, and re-energizes and rejuvenates the body.
This pose should not be practiced by people with recent or chronic injuries of the back, hips or knees. A pillow or a folded blanket can be placed below the knees to ease any discomfort. To deepen the stretch, the practitioner can place a hand on the top of the knees and pull them lower.
