GYM: Hip Dips
Stand on a step, or something similar, with one foot lined up along the edge of the step and your other foot hanging off to the side.
Without bending the knee of the leg you are standing on, raise your opposite hip so that the foot that is hanging off the edge raises and becomes nearly even with the level of the foot that is on the step.
As you practice this hip-stabilizing move, you likely will be able to get your hanging foot to actually reach a level higher than the step. The movement is generated from the hip on the weight bearing side.
Repeat this exercise for 3 rounds of 12 on each side.
