No other ab workout product in the world supports your spine to move the way it was designed by nature.  Here's how Ab Roller® and Ab Trainer® products support natural movement while you do abdominal crunches:

Our spines are made up of a series of 33 bones called “vertebrae.”  When you move your back, these vertebrae flex together as one, in a curved motion.  This movement is very different from the movement of other bones in our bodies which pivot from one joint—like the knee, elbow or wrist.  Our spines don't pivot.  Instead, through the series of vertebrae, our spine flexes in a naturally curved rocking motion.

The secret to the effectiveness of the Ab Roller is the patented “Arcuate Rocker System.”  This patented technology is only available on official Ab Roller and Ab Trainer workout products.

The Patent that Protects You

Our patented Arcuate Rocker System comprises of a curved rocker design that serves a double function: 

1) It provides support for the head and neck during your ab workout, and
2) It guides your spine through a natural curved movement (this is called “spinal flexion”)
     during your ab workout.

The patented Arcuate Rocker System available in our entire Ab Roller product line ensures that your spine will never “pivot” during your abdominal workouts.  The Ab Roller will always make sure that your spine moves in a curved motion the way nature intended, because the Arcuate Rocker System literally mimics spinal flexion. 

In addition, the headrest support, which is attached to the rear of the unit, moves in concert with the Arcuate Rocker frame of the unit.  This design allows your head to move together with your spine so that proper alignment is maintained while you exercise.

Avoid Injuries from Abdominal Crunches

Many people perform ab crunches (or “sit-ups”) by using their hands behind their neck or by using a towel to support the head.  These things commonly lead to pulling on the neck.  Plus, many people pivot forward, using their hip flexors to pull up rather than using their abs to curl forward.  This common mistake results in back and neck pain as well as lack of motivation to exercise.  Most ab workout machines cause your spine to pivot, not to roll and flex like the Ab Roller.  With the Ab Roller product line, there is no painful pivoting or pulling.

Our patented Arcuate Rocker System helps your spine move in a naturally-flexed manner for a safe and effective abdominal crunch workout.
