Does Exercise Fasten Your Metabolism?

How does exercise affect metabolism? Exercise can boost your metabolism. Building lean muscle mass by exercising can slightly increase your resting metabolic rate (the amount of calories your body burns while at rest). In addition, vigorous exercise can increase your metabolic rate for hours after exercise.

How much does exercise increase metabolism? Breaking up a 60-minute workout into two 30-minute (or three 20-minute) sessions is not only convenient, but also it may help you burn more fat, according to recent research. Forget about three large square meals a day.
