HOW IT WORKS...
Inside its tough, impact-resistant casing is the secret... the Cross Crunch™ progressive power system. Just set the resistance to your fitness level, then simply sit and crunch down and across.
This powerful diagonal crunching motion produces a compound dual action that targets and sculpts your upper abs, lower abs and side obliques.
That’s your entire abs, all in one easy motion that's more effective than old fashioned floor crunches.
