Running is one of the most simple athletic endeavors humans can do, mainly because no equipment is needed—technically not even shoes (though our 21st century living environment calls for them). Running for an hour at 8 mph burns 1,074 calories per hour for a 200-pound person, according to fitness expert Chris Ryan, CSCS, CPT. Because it requires a serious amount of energy to move this fast and places quite a lot of demand on your cardiovascular system, most of us can’t sprint or run too fast for too long. “The best way to incorporate this exercise is to do 10–20 second sprints (or 100–200 meters, if on a track) and then jog or walk for 60 seconds,” says Roger E. Adams, PhD, Houston-based dietitian and nutritionist and founder of eatrightfitness.com. “Keep repeating these intervals until you’ve had enough, or until your sprints look like jogs.” Hoping to maximize your workout even more? Add a weighted vest to your sprints. This will drive up your calorie burn and is much safer than holding dumbbells or using ankle weights. Check out these easy ways for walkers to become runners.
