Builds strong glutes by driving your hips up against a weight. That's the power you use to climb stairs, stand up and run.
How to Do It
Sit on the floor with your upper back against the edge of a bench. Rest the weight on your hips and hold it with both hands. Plant your feet and drive your hips up until your body is flat from shoulders to knees, then lower slowly.
Tips
At the top, your shins should point straight up and down. Tuck your chin and ribs so your lower back doesn't arch.
Skill Level
