Build your bridge exercise for leg and core strength.
Begin lying on your back with both knees bent and your feet flat on the floor. Pull your belly button in toward your spine, squeeze your glutes and lift your hips up about 6 inches. Maintain this position, and lift your right foot up off the floor. Slowly lower your right foot to the floor. Keep your hips up and lift your left foot up off the floor, and then lower your left foot to the floor. Do 10 reps total, and then release your hips to the floor.
*Consult your physician before performing exercise.
