The Cross Crunch Abdominal Exerciser is a hand-held piece of training equipment that targets the core abdominal muscles. It works by creating more resistance than a typical crunch would. The pivoting motion that is required also engages more of the abdominal muscles, including the uppers, lowers and obliques. As of late 2010, the Cross Crunch Abdominal Exerciser costs $30 and can be purchased at the product's official website. Consult a physician before beginning any exercise regimen.
Posture
To improve your Cross Crunch technique, make sure you have good posture. For best results, sit down on a flat surface that doesn't have a back (like a weight bench). Your back should be straight and tall and your chin parallel to the floor. This posture engages the muscles and makes you work harder to complete one repetition.
Use All Muscles
Remember to work a variety of muscles when using the Cross Crunch Abdominal Exerciser. Though it's primarily intended to work out the core, you can also work our forearms, biceps, chest and back. For best results, tighten the area or areas you wish to work before doing a repetition.
Increase Resistance
The Cross Crunch allows users to adjust the resistance up to 75 lbs. As it becomes easier to use the exercise device, increase the amount of resistance it provides. According to the University of Arizona College of Agriculture and Life Sciences, resistance training increases bone density, weight loss and muscular strength.
