The Fitter You Are, The Faster Your Metabolism Becomes

This is true, but only up to a point. Yes, becoming physically fit - building muscle and exercising aerobically - does increase your metabolism. But the more physically fit you become, the more efficient your body becomes too. It recovers quicker from exertion, taking a shorter amount of time for the heart rate to return to normal, and your muscles don’t have to work as hard to achieve the same results. So in the long run, the metabolism of a fit individual tends to level out. All that work that it takes to stay fit, however, does burn calories, so if you vary your exercise routines and change them up regularly, it will help to burn the maximum amount of calories. Adding periods of intensity to your workout (sprints or interval training, for example) is especially good at revving up the calorie burn of your routines. So don’t do the same old thing every time you put on your workout gear. Get creative. Have fun. Be willing to try something new. And play hard!
