The Ab-Cruncher is designed to work both your core abdominal muscles and your all important side oblique muscles.

By laying on the board, and tucking your feet under the bottom rung, lift your body to a controlled upright seated position and then lower again. To increase difficulty, move your arms from beside your body to across your chest or to behind your head.

Mix up your exercise by using the chin up bars. By holding the grips and lifting your body up towards the bar you will provide an intense upper body workout for your arms, shoulders, back and lateral muscle groups.
