As well as stretching the side of the body, half circle offers the following additional benefits on a physical level:
- Opens the hips
- Stimulates the respiratory system
- Soothes the nervous system
- Activates the thymus gland, which boosts the immune system
If kneeling is painful for the yogi, a folded blanket can be used to cushion the supporting knee as a modification for this pose. Half circle can also be entered from side plank rather than kneeling, which some yogis find more challenging and strengthening.
