I hate working out (I mean HATE it) but I love 9Round! The trainers keep me motivated and the 3 minute rounds make it easier to make it through. Every time I think I'm not going to make it through the round, the 30 second warning beeps and I know I can push myself harder for just that much longer. The heart rate monitors are awesome and help me motivate myself to push and burn more calories (it sends you a workout summary after every visit). I haven't stuck with working out this long in my entire life and I don't plan on quitting anytime soon! This is what I've been looking for. Thanks 9Round!!
