Lie on your back with your feet hip width distance apart and flat on the floor.
Place a medium to heavy weight dumbbell gently on your hips (be careful not to bang your hip bones).
Holding the dumbbell in place with your hands, draw your belly button in toward your spine and drive up through your heels as you raise the hips, squeezing your glutes all the way up.
Make sure you get full extension in your hips to get maximum squeeze in your butt.
Slowly return back to the start position to complete one rep.
Perform two to three sets, 10 to 15 reps on each side.
