In your mid-20s, your metabolism slows down, and your body starts burning fewer calories . . . up to 200 less a day. Then at 40, your body REALLY starts packing it away. But it doesn't have to. Here are five easy ways to burn 500 extra calories a day . . .
#1.) WORKOUT OUTSIDE. You burn 10 percent more calories running outside than you do on a treadmill. Treadmills drag your feet, and you don't have to propel yourself forward. And running into the wind, even if it's a slight breeze, burns more calories.
#2.) ALWAYS WARM UP. Most of us don't take the five minutes to do it, but we should. For every degree your body temperature goes up, your metabolic rate increases by 13 percent.
#3.) RUN AT DIFFERENT SPEEDS. Bursts of intense activity make you burn more fat than running or riding a bike at one constant speed. And even after you're finished, it makes your body burn about 15 percent more fat than it would otherwise.
#4.) DEVOTE ONE HOUR, ONCE A WEEK. Researchers found that people who worked out for an hour burned nearly five times as many post-workout calories as people who only exercised for 30 minutes.
#5.) USE HEAVIER DUMBBELLS. You burn 25 percent more calories lifting 20 pounds five times, than you do lifting 10 pounds ten times . . . even though it's the same total weight.
--And researchers say that even if you can only do sets of 3 to 6 reps with heavier weights, it makes your body burn up to eight percent more calories every night while you SLEEP. (Prevention.com)
