How to Get Fit

Energy In, Energy Out

When it comes to body weight, remember this: 1 pound = 3500 calories. For every pound you want to lose, you must burn 3500 calories worth of energy. The only way to do that is to move more.

Walking is one of the best forms of exercise. It uses up oxygen, causing your body to burn stored fat. For example, you'll expend about 100 calories by walking a mile. That might not seem like a lot at first, but just think about it. Most people average just under 3 miles through the course of their day. If you add an enjoyable morning jaunt or a brisk evening walk you could easily move 4 miles a day. If you walk 4 miles 4 times a week, you can burn 1600 calories! That's half a pound of fat gone. Add more steps to your day while making sure not to eat more calories than you use, and your body can't help but trim down.

Walking also strengthens muscles, which tones and shapes your body. The increased muscle mass boosts your metabolism. This means you burn calories long after you stop moving. And you don't have to get all of your walking in at once. If you don't have time for long walks, find pockets of time throughout your day for short jaunts.
