Spinning

Spinning is another highly-popular form of group exercise, and another one where calorie counts are widely varied. Working at a relatively -low intensity, you can burn around 300 calories an hour. However, as you increase the intensity, you'll increase your calorie burn. Adding bursts of speed and using high resistance can help you burn up to 800 calories in an hour. It's certainly not for the faint of heart, but is one of the best classes for burning loads of calories.
