Get strong and sexy abs by doing these crunches on ball. Tone your abdomen muscles by balancing yourself on the ball and performing crunches. Below are the steps to perform crunches on the ball.

• Take a stability ball and position your back on the stability ball.
• Raise both your hands towards the head and cross them over the head.

• Now inhale and expand your stomach.
• Now raise your head with the help of the hands while maintaining the balance on the stability ball.
• Exhale and contract your stomach while doing the above step.

Note: If your head and neck muscles get tired very soon than your position on the ball is not proper. Just again balance properly on the stability ball and try the crunches again. While doing the crunches place your tongue upwards in the mouth. This would help the muscles deep in your neck kick in.
