Roll N Flex Ab Roller Abdominal Muscle Trainer and Flex Workout

The whole concept of this trainer is very interesting, and after youttube videos I realize that its not only for abs, but a whole body machine. Manual that comes with it is also provides a lot of information, but it much more easier for me when you can actually see how to do it right. Will reccomend it for all who is trying to get in shape and loose some weight.
