Standing Crossover Side Stretch
For the outer hip, which often feels tight after a long run. Stand tall, cross one ankle in front of the other, raise the arm on the back-leg side overhead and reach it over toward the front-leg side. You should feel a long stretch down the outer hip and side of the back leg.
This is often sold as an IT band stretch, but the band itself is tough connective tissue that barely stretches; what you are really easing is the muscle around the outer hip. It feels good all the same. Hold 20 to 30 seconds per side, using a wall for balance if the crossed stance wobbles.
