Step out to the side and bend this leg, feeling a stretch through the inner thigh of the extended leg.
Next, turn into a prisoner stretch, dropping the back knee down to the floor and pushing your hips forward with your hands behind the head as you lean into the bent leg.
You will feel the stretch in the front of the back hip.
Finally, go into a pigeon stretch, tucking the front leg underneath you, and sitting down to stretch through the buttock muscles.
