Standing Leg Cradle

This active glute stretch opens up the back of the hip, priming all the muscles in your butt to fire.
Begin standing, and lift your right leg up, catching the shin and the ankle.
Open the right knee to right, and hold for a moment to feel the stretch. Lower the right leg, and repeat on the other side. This completes a rep.
Keep alternating sides for 10 reps total.
