I think that the ab roller is a great piece of equiptment for a home gym. It provides an amazing ab workout because it really works the entire core as opposed to a specific part of the stomach like most traditional ab exercises. However, I consider myself a very active and fit person. Exercise is a part of my routine every single day and I was a college athlete. I used my roller for a few months and am certain that I was using it properly. I have seen people using them in my gym and watched the workout tape and followed the moves. Initially I was worried about the lateral stability of the roller: would I wobble side to side or roll over? This was not a problem at all, I felt much sturider than expected. All exercise equiptment warns against "exercising till exhaustion" and I was working hard on the ab roller, but not to that point. While moving down for a rep I wasn't putting enough pressure on the roller and literally fell flat on my face as the roller went flying forward. It was painful and I didn't have anything to protect my face, i will not use the roller again.
