If you’ve ever had only 30, 20, or even 10 minutes to break a sweat and wondered if it’s worth it—it is. There’s a common misconception that hitting the gym for hours on end is the only effective way to exercise. Not only is that completely unrealistic, but it makes working out seem like such a chore.

Whether you’re trying to squeeze in a quick sweat before work or just can’t stand the thought of spending an hour on the elliptical (again), here’s how to optimize your workout routine when you’re pressed for time.
