Lift the bottom of the belly and extend the thighbones away from the body, slowly rotating the legs away from the hips. In the full pose, the left knee is on the floor and the right ankle is on the left knee.
Hold for 3 to 9 breaths, then change sides.
If, when you do full pose, the upper leg is higher than a 45° angle from the ground, do the following variation instead:
Start with your knees bent, feet on the ground with your heels in line with your sitting bones. Cross the right ankle outside of the left knee.
Use a strap to lasso the right ankle; bring the strap up towards your shoulder and hold it like a ski pole, with the back of your hand towards the ceiling and your thumb towards your head.
Straighten your left leg on the ground, keeping the right ankle just above the left knee as you extend the left leg. Slide your hand on the strap so it rests on your left hipbone (ASIS).
Keep your feet active with toes flexed. Keep the left leg active, quads contracted with all the toes pointed to the ceiling and the foot flexed.
Take your right hand to your right thigh and use it to externally rotate your right thigh and traction it away from the socket. Lift the bottom of the belly. Move your right knee away from your left hipbone and your left hipbone away from your right knee.
Hold for 3 to 9 breaths. Repeat on the left leg.
