Rowing is sweeping the fitness industry and for good reason. You do this for one hour and it burns 600 calories! I'll admit you're probably not gonna row non stop for an hour, but you could do 15 minutes a day and lose one pound or more a month. But lets remember it's not about your weight, it's about keeping your ticker beating, your muscles strong and your joints fluid. If you choose a rower with a sliding seat you'll get a great upper and lower body workout. Rowing is natural and low impact so it puts less stain on your joints.
