The tread will start to slide off the wheel drum. Have to watch it and force it back into place.

Greatest ab workout ever!!!!

I don't need to spend a ton of money on a roller to do abs.I was in need of a new one because my old one was worn out. I took a chance on this one because of the ergonomic grips and the curved roller so you can easily do obliques.It has in integral spring to "assist" you in coming back, but it doesn't do much (at least on carpet).It's held up for a while now with no issues so that's the bonus.These rollers are the real deal. They are difficult and give you a workout. I use mine 5x/week, the results are noticeable.Seems like a good roller for the price
