Summary: DEAL with it
Comment: After a lengthy bout with chronic illness, I'm gradually building up muscle mass and physical strength again. Following injuries from a car crash, I really must have support to do the sit-ups that are essential to managing form and function.
I bought this from Amazon ONLY BECAUSE of Amazon's excellent return policy. Though I was initially skeptical of the TV ads, I am VERY impressed with the Ab Rocker. I was able to set it up myself without any help from anyone. Very little work involved, mostly pre-assembled. If my hands were more arthritic, I suppose I would have needed some help with the tension springs.
I've used it about 4 times and already achieved significant changes in my abdominal profile (and the fit of my jeans). You have to work with the machine the way that it is made. I expected the rollers to massage my back while I was exercising, but they don't really do that for me. What they do IS awesome, though. When you have reached full extension and the machine back is on the floor under you, then you just relax into the rollers and let them provide gentle pressure for a few seconds before contracting to return to upright. While you are relaxing your back into the rollers, pay attention to how your abdominal muscles are contracted. You may be surprised at the locations and the effects achieved.
Also, be sure to set the upper most roller to support your NECK, NOT the back of your head.
If used properly, this machine delivers. It probably is a little over-priced for it's category. The market it serves best would be better served at about $59 - $69, rather than Amazon's current price of $99. Single moms, military wives, folks with less discretionary dollars would probably buy it at a lower price point. Watch for an Amazon sale, folks!
