Start the hip bridge by laying on your back. Place a medicine ball or small step beneath one heel and extend one leg. Start by bracing your butt then your abs and without losing any tension, drive your hips up and open them. Don’t let the side with the leg extended droop. The goal is to keep a straight line from the heel through the hip and into the shoulder. Keep your belly tight and squeeze your butt! Keep the tension as you lower yourself back to the ground.
Control the heel on the ball and don’t let it get away from you!
