How to Perform Reverse Sit Ups Using a Physio Ball

A physio ball, or exercise ball, is a large air-filled ball you can use in Pilates or aerobics classes to help strengthen muscles and increase flexibility. Doing crunches on a physio ball reduces stress to your back and provides a more efficient workout than traditional crunches. Follow the steps to learn how to do reverse sit ups using a physio ball to tighten abdominal muscles and burn excess fat.

Instructions

1. Gather a yoga or exercise mat and a physio ball and sit in an open area where you don't feel too crowded. Leave room on all sides of you to avoid bumping into someone else.

2. Lie flat on your back on the mat with your legs at a 90-degree angle on top of the ball. Keep your neck relaxed to avoid overextending.

3. Hold the ball between your heels and buttocks, applying slight pressure to keep the ball stable.

4. Place your hands on the floor beside you, arms straight and palms flat. Relax in preparation for the exercise.

5. Tighten your abdominals and buttocks and lift your feet off the floor, tucking the ball into your body. Bring your knees to your chest, applying constant pressure to keep the ball stable, and hold for a few seconds.

6. Lower your legs and the ball back to the mat. Exhale and tighten your abs as you slowly lower your body back to the starting position. Repeat 3 sets of 10 as part of your normal workout.
