The reason itself doesn't matter so much -- maybe you lost a bet to try it for a month, or you had some surprising feedback from the scale, or you're trying to quit smoking and rehab your lungs. Lemmer recommends thinking about your reason (or reasons) for running every morning when you wake up, and every night before you go to sleep, in addition to before, during, and after your runs.
"Running is a journey," Lemmer says. "There are going to be days when you question your decision to start, and when you question whether or not you can continue. But the mental and physical benefits are so, so worth every difficult step you take along the way."
