How to do it:
- On a soft surface, get to the all-fours position (kneeling position with your spine parallel to the floor, your hips on top of your knees, your shoulders on top of your hands)
- Spread your knees as wide as is comfortable while maintaining your shins parallel and back flat.
- Push your buttocks back toward the floor like you’re trying to sit back onto your hips.
- Hold for two breaths. Return to the starting position and repeat for approximately 10 repetitions. See if you can sit deeper with each repetition.
