Overview

Medicine-ball crunches target and define the abdominals. Using a medicine ball increased the resistance on the abs and obliques. This additional core muscle recruitment leads to faster results.

Description

• Lie on your back with your legs bent and feet flat on the floor.
• Hold the medicine ball at your chest, close to the chin.
• Keeping your neck neutral, roll your upper back off the floor.
• Return slowly to the floor.

Mistakes

• Jutting the chin as you crunch up
• Holding the medicine ball too low toward the stomach
