This is an excellent stretch to try out for hip pain, especially if it is related to bursitis.
Kneel on the leg that's giving you the pain (holding on to something sturdy for balance).
Tilt your pelvis forward, tightening your gluteus muscles (the muscles in your buttocks).
Then lean away from the side of your hip that hurts. For instance, to the left, if you're kneeling on your right knee. You should feel a stretch from the top of your hip bone down the side of your leg to your knee.
Hold the stretch for 30 seconds and repeat once or twice.
