I been working out and trying to get into shape so i'm always looking for different types of exercise equipment/tools to help me out. What I like about this ab roller wheel is that it is easy and quick to put together. You just slide one of the handles onto the metal wheel axel, once it all the way through, just place the other handle on and push it together. There is a quick start guide that helps get to help you know how to use it. I hate having to get my knees red & sore from exercising on the carpet while exercising and I like that this ab roller wheel also includes knee protectors to keep that from happening. The way you use it while on your knees, hold both hands onto each side of the handles and roll it forward then bring it back and keep repeating. I can tell this definitely works on my abs because I can always feel it. I love to use it everyday.#RankBoosterReview #Sponsored #PureGoal
