@reviewsbycole: The easiest way to build your abs at home. This wheel (well actually 4 wheels) is perfect for focusing on the core. Less of the lower back. It actually assists you just enough on the way back. Feels smooth on the floor and comfortable to rest the arms on. If you want to take your ab training seriously, check the link in the bottom left corner of the video. #ab #core #abwheel #coreworkout #6pack #homeworkout
