I purchased three wheels for family and friends. Not only is it a great gift for the hard to buy for, but also inexpensive. As my son is starting to workout, his friends became interested in how this wheel in his room worked. After showing them how to use the wheel, everyone wanted to try it! It started out to be a try it, which lead to a competition that had everyone trying to outdo the others. It made for a lot of fun and laughs. I suggest anyone that would like to do ab workouts to try this inexpensive wheel and see how well it truly works. It not only gave them something to do but was fun as well as physical. My son now has a great six pack going, and enjoys showing off his flat hard stomach!

This machine really works your Abs. At first, you will have some back pain, but after that everything is okay!

Bought this program after reading one of those "Get 6-pack" stuff online. And it gives a nice workout! Heard about it...wasn't too sure about it but it's worth it! As a person who works out regularly i recommend this equipment for any1. Easy to assemble! Have fun..hope this helped...

It was really hard to assemble. The handle cover was too tight and would not come in.

I didn't have any problems putting it together mainly because I read the reviews here at Amazon before purchasing one and saw a review where someone used a small amount of petroleum jelly to help the grip slide in.
The wheels may seem a bit shaky but, when its being used and your weight is on it, it'll do its job. And don't worry the wheels won't slide off the sides.
I didn't have any experiences using an ab wheel before so at first I was wondering why a lot of people would have difficulty with this device when it seemed like a simple enough exercise. I was completely wrong! At first, It was really hard to do those full extensions and I could feel my abs burning (which for me, is a good sign which means its getting worked out pretty good) and I felt my back being toned too.
Overall, it does its job well. And its an exercise piece that's small enough to store easily and its absolutely worth the money. Its a great buy!
