If you think you’re too busy to exercise, try this experiment: For one day, schedule a time to work out, and then stick to it—even if you can exercise for only 10 minutes. “At the end of that day, ask yourself if you were any less productive than usual,” The answer will probably be no—and your favorite excuse will be gone.
