How to Do Legs on Balance Ball Abdominal Crunches

Using the balance ball while doing your basic abdominal crunch can make your workout more enjoyable while working different muscles. Try this variation the next time you work your abs.

Difficulty: Easy

Instructions

1. Start by lying on your back with a mat on the floor. Put your legs on the balance ball and bend your knees at a 90-degree angle.

2. Cross your arms over your chest and focus on a spot on the ceiling. Tighten your abs. Slowly lift your upper body and bring your chin up until your body is at a 30-degree angle. Pull your shoulder blades up until no longer touch the floor. Keep your lower back on the floor to maintain a good form.

3. Hold the position briefly, and then relax your abs. Slowly lower your body back down to the starting position. Begin the next crunch without resting.

4. Repeat the exercise 12 to 15 times for 3 sets. As your fitness level improves, add sets and repetitions to your workout.

5. Vary the exercise by putting your hands behind your head or by placing your arms straight above your head. When you put your hands behind your head, don't pull on your neck or head; you could strain your neck muscles.
