Ball Roll Outs And Bridge
Start with your back on the floor and your feet on an exercise ball. Slowly raise your hips in the air and keep them raised as high as you can as you roll your legs out until your body is flat. Squeeze your glutes, and keep your hips high as you roll back in. Perform three, and then lower and raise your body from the pulled-in position as you make a bridge. Keep the exercise ball motionless for the bridge. Works your entire backside!
