Where does most of the fuel you burn during exercise come from?

Saturday, April 11, 2015


Most of the fuel you use during exercise doesn’t come from the food you've recently eaten! It actually comes from the carbohydrates (called "glycogen") and fat that's stored in your muscles, liver, and fat cells. That’s enough to fuel 1-2 hours of very intense exercise or 3-4 hours of moderate intensity exercise.
