Great tool for an overall upperbody workout. Take it slow at first, cause you will feel it the next day. I cycle, run, and lift weights almost daily. But I was only able to do 5 wheels the first day I got it, and it felt like my abs were going to rip apart. :) But after just a couple of weeks, I am up to 30 at a time. Love it. I can feel it working shoulders, abs, upper and lower back, biceps, triceps, and lats. Great complement to any workout routine. A good way to "top-off" after lifting weights.
