caption: Slide 3 of 6: With your yoga wheel positioned behind your back, sit on the floor with your knees close together and your feet flat on the ground. Lean back over the wheel in a position that's comfortable. When you feel ready, and only if you are able, take your arms back, reach over your head and bend your elbows. At first, you may not be able to go all the way back. That is OK; the more you do the stretch, the easier it will become to get fully extended into Half Pigeon.
