Many people believe that in order to burn fat, they have to do tons of cardio. The key to burning fat is actually strength training! The more muscle you have on your body, the more your metabolism will increase, which will help you burn calories faster. In fact, having just one extra pound of muscle on your body will help you burn an additional 30-80 calories each day! Doing a strength training workout will burn about as many calories as a cardio workout, however without the muscle, you will not be able to burn those extra calories afterwards!
