What I like is that this is a very stable structure and did not wiggle much when I was using it! I felt it targeting my abs and arms, which is much needed! It is fairly small so it does not take up much space. It also does not leave any marks on your carpet when you use it. It is maintenance and works well! :) Great for anyones home gym!
It does not come with any instructions, so here is how to assemble it:
You just take the white metal pole and put of the handles on then a wheel, then another wheel and then finish it with the other handle. There should be none of the white bar that shows once you are done. If you do, try having it upright and push down with your weight, sometimes the handles seem like they are in all the way, but they are not if you still see white. It also comes with a blue knee pad so for comfort.
