Easy crossed leg pose.
Monty suggests combining with stomach grinds.
Place one hand on each knee. Gently engage core. Make a small slow steady circle around your center with your belly button or top of head. Focus on steady breath. After a minute switch directions (clockwise and counterclockwise). Then switch your legs (other leg on top) and repeat.
May aid in digestion and realign organs in your core, great for circulation too!
