Crunches on the Swiss ball offer several advantages over more conventional methods and machines. Using the ball facilitates full flexion and extension of your spine thereby training your abdominals through a full range of motion. Crunches on the ball also promote balance and stability stimulating your deeper core muscles in addition to the prominent rectus abdominus or ‘six-pack’ muscle. When done correctly the Swiss Ball crunch is super effective.
