Up In Arms *Upper Body Ergometer*

Been looking for an aerobic/cardio exercise that would work my upper body. Though I spend a lot of time on my lower body, burning calories and working up a sweat, my arm flab and back rolls dont budge. Don't take me wrong. I love having arms and a back and I appreciate that I can feed myself. My back rolls and arm fat prove it! But there has to be balance in not only what I eat but how I exercise. So I need to work out this top half. I started using the row machine today. Which is awesome and fun. But I been eyeballing this thing called the Upper Body Ergometer. It's like a bike, but for your arms instead of your legs. I've read that you dont necessarily or as easily break into a sweat as you would a lower-body machine. But with practice you will burn calories and seriously condition your arms. Hmph. Well we shall see. I'll try it tomorrow!
