When it comes to lasting calorie burn, vigorous-intensity exercise could be the gift that keeps on giving. New research published today by the American College of Sports Medicine reports that a 45-minute bout of vigorous exercise can boost a person’s energy expenditure for up to 14 hours.

Researchers with Appalachian State University and the University of North Carolina at Chapel Hill examined energy expenditure among ten healthy, male participants during two nonconsecutive sessions of 24 hours in the metabolic chamber.
