1. Exercise Ball Bridge

Lie down with your back straight, bend your knees, and finally put your feet flat on the exercise ball. Let your arms rest on your sides and keep your palms down. Draw in your belly button and maintain this throughout the exercise.

Contract your glutes and bring your hips off of the ground. Make sure your knees, hips and shoulders are in line directly with one another. Stay in place for 2 seconds and the very slowly lower your back down and do it again. Do this for 2-3 sets and do between 10-12 repetitions.

2. Exercise Ball Crunch

Lie on your back on the exercise ball with your face towards the ceiling. Keep your knees bent and feet flat on the floor. Put your hands behind your head.

Now, do a normal crunch like you would on the floor. Get your shoulders off of the ball and slowly go back to the starting position. Do this for 2-3 sets and do about 10-12 repetitions.
