If you have trouble staying motivated to exercise, you might achieve greater success if you make exercise part of your routine -- something as ingrained as brushing your teeth, getting showered or driving to work. The more "automatic" exercise becomes, the less you'll have to grapple with how to fit it into your busy schedule.

How do you do that? Keep in mind that your health is not a temporary change to be made; you're making this choice for a lifetime. Your teeth need to be brushed regularly in order to keep them healthy, right? Same goes for your body. Get into a routine you like and stick to it!
