It's important to understand that while some diets, trainers, and exercises may promise to take fat off of just one area: they're lying or very confused.

Exercising as a way of getting around is another good way to fit exercise into your day. You can bike to work or school, walk to the grocery store, or walk or jog to work, if you've got space to get cleaned up afterwards. If you've got a lot of distance to cover, try taking a bus part of the way and then biking or jogging the rest. A lot of people lose steam on exercise because they do things like sit ups, which are difficult to do and don't work very...
