Q: Is it okay to be a weekend warrior— someone who exercises, works out or plays a sport only on weekends?
A: It’s better than not exercising, but more frequent workouts are preferable. Some of the physiological benefits of exercise—on blood pressure, for instance—are relatively short-lasting.
Moreover, the risk of injury is greater with occasional workouts, especially if you are cramming in strenuous activities. Your muscles may not have time to adapt to the stress of exercise.
The best plan is to make time for some exercise most days—even 10 minutes now and then. If you have to limit your vigorous workouts to the weekends, try not to push too hard.
