Side Lunge

The side lunge works the muscle on the side of the pelvis as well as the inner thighs.

Holding a 2 to 4kg weight in your left hand, stand with your feet and knees together, hands on your hips.
Take a large step with your right foot to the right side, and lunge toward the floor.
Make sure your right knee does not extend past your toes, and keep your left leg relatively straight.
Push off through your right foot to return to the start to complete one side lunge.
Do three sets of 10 on each side.
