Rowing vigorously helps you burn off more calories in a shorter period of time, because it's all about power. The more power you apply, the more energy you use, and the more calories you burn. In short, maximum effort leads to maximum calorie burn. For example, if you can burn 501 calories in an hour rowing at 100 watts, you'll be able to You can burn more than 800 calories per hour or a quarter of that number, depending on how much you weigh, how vigorously you row, and a few other factors.
