How to Do a Balance Ball Reverse Crunch

The reverse crunch simultaneously uses your abs, your core muscles, your back and your arms. Performing this exercise regularly will tone your midsection, strengthen your back and build up your arm strength.

Instructions

Difficulty: Moderately Easy

Things You’ll Need:

• Balance ball
• Floor mat

1. Kneel on the floor mat with the balance ball at your feet. Assume the push up position and put one leg and then the other on the ball. Keep your hands shoulder-width apart and under your shoulders.
2. Roll the ball so that your toes are on the ball. Stabilize your body and make sure you're balanced in the center of the ball and that your hands are the correct width apart.
3. Begin the crunch by engaging your abs and curling the ball toward you until your knees are bent. Hold the position for a second, and then return the ball to the starting position. Keep your back straight and your abs tight while performing the exercise.
4. Repeat the exercise 12 to 15 times for 2 sets. As you get stronger and more familiar with the exercise, add repetitions and sets to your workout routine. Your goal should be 25 repetitions per set.
5. Vary the exercise by keeping one leg on the ball and the other extended straight over the ball. This move adds an extra balance challenge, making it harder for your abs to complete the move.
