This exercise will not only stretch your hip, but it is a great way to warm up before play or practice.

Use a club for balance.
Stand on one leg and place the other foot on top of your knee, so that you are balancing on one leg.
Squat down as far as you can to feel a stretch in your hip and glute muscle.
Hold position for 10 to 15 seconds.
Release and repeat on opposite leg.
