Millions of people from around the world experienced the original AB-DOer®, but now it's time for a quantum leap forward-- the AB DOER TWIST™, the 360-degree approach to total-body fitness. To get in great shape you have to do muscle toning and aerobic activity. With the AB DOER TWIST™ you do muscle toning and aerobic training at the same time - and from, a seated position. In just minutes a day, you'll experience a fun and exhilarating total-body workout. The core support column and contoured arm bars support you in the perfect position to achieve maximum results. Only the AB-DOer®'s patented torsion-flex technology fires up muscles that other exercises simply can't reach-- your lower abs, upper abs, obliques, even your back. You're aligned, you're stable, and you're being supported. This lets you use your muscles much more effectively, with less stress and less strain - plus the foam roller gives you a revitalizing, therapeutic massage every time. With the Power Resistance Kit, you can tone up your arms, shoulders, chest and back and even your inner thighs, hips and buttocks. The Power Resistance Kit allows you to perform the same exercises you would perform at the gym with dumbbells and barbells and cable machines. Simply attach one end of the Power Resistance Kit to your AB-Doer Twist and curl, press and row. To work your lower body, simply secure the comfortable ankle stirrup around your ankle and kick, lift and push your legs, hips and buttocks into their best shape ever. Variable resistance options keep you challenged and realizing great results from workout to workout.
