Mini Band Reverse Hypers
To do Mini Band Reverse Hypers, place a mini band right below your knees. Lie face down on a bench with your hips right at the edge of the bench. Grab onto the bench and place your heels together and toes turned out. Bend your knees, bringing them in toward the bench, pressing out against the band.
Then kick your legs out, driving your heels toward the wall behind you as you press your hips down into the bench. Press out on the band as your legs go straight. Squeeze your glutes to extend your hips then bring your knees back in and repeat. Press out on the band as you bend your knees.
Press your hips down into the bench and focus on extending your hips, using your glutes. Do not let your low back take over.
