The primary logistical barrier to exercise is time. Lack of time is the most commonly cited excuse for not exercising. But surveys suggest that those who exercise regularly are just as busy with their jobs, families, and other responsibilities as those who don't work out. So the time excuse is just that: an excuse. We're all pressed for time, yet we all have time for our highest priorities. If exercise is important to you, you will find the time to do it.
