Spinning is the new inception for a fit body and mind. Is also the best exercise to burn about 600 calories in 45 minutes. The resistance, time duration, and speed of the spinning bike help use up the calories consumed and mobilize the stored fat. Any other form of cardio - say running, sprinting, swimming, or dancing - will only burn 300-500 calories in 60 minutes. So, if you are ready to shed some body weight, come spinning.
