You Can't Recall When You Last Broke a Sweat
Working out is about more than just losing weight—it has proven psychological benefits, like reducing anxiety and depression. If you haven't exercised in a few weeks, you might be in a vicious cycle: Too busy and stressed to work out, which in turn prevents you from getting the stress relief you probably need.
Try this: No matter how busy you are, it's important to work exercise into your weekly schedule. The easiest way is to start with a walk during lunchtime. If you've gotten into a rut and are too tired and busy to work out, try scheduling workouts with a buddy so that you keep each other committed. Stick with your new schedule for a few weeks—usually it takes about 21 days to get back on the habit horse.
