Simple Diet To Exercise

A That all depends on how hard you're working. All things being equal, running outdoors may burn 7 to 10 percent more calories than working out on a treadmill because of air resistance and the fact that you don't have the machine's belt helping to propel you, says Cedric X. Bryant, Ph.D., of the American Council on Exercise. In addition, running on uneven terrain like sand or a sloped sidewalk requires more energy than running on a flat surface--but the difference may add up to just 20 to 30 calories during a 30-minute workout. "If you kick up the treadmill incline, you can burn the same number of calories as running outdoors, maybe even more," says Bryant. The same goes for cycling indoors--a high-intensity Spinning class will blast more calories than a leisurely cruise outside. Conversely, when you're biking on a trail, fighting a headwind, or working to keep your body balanced while heading uphill, you'll definitely sweat more than when you're pedaling on a stationary bike. One big advantage of outdoor workouts: If you spend the winter months at the gym, a change of pace could be just what you need to shake up your routine and push a little harder!
