Rowing machines are evil and fantastic workouts. You work your legs, core, and arms. The only worse machine is the Schwinn Aerodyne....those are the DEVIL!!!!
Im sure people at the gym think i'm absolutely insane on it since all i do is listen to comedy stations so i'm on the thing pooring sweat and laughing to myself. I get some great looks of confusion and curiosity. But i had another day where i burned 400+ calories in under 30 minutes and got a full body warm up from hell.
