Circuit training workouts have the notoriety of being some of the most intense workouts ever. They often combine heavy lifting and high-intensity cardio, giving you as much bang for your back as you can manage. What’s great about the workouts is that they are short. After all, at that level of intensity, going for a long period of time is too physically demanding for most people and may do greater harm than good.

What some people might not know about the workouts, aside from their brevity, is that you don’t necessarily have to go to a gym or workout facility to experience it. In fact, you can do some of them right in your own home. Try the workout video above or these CrossFit exercises below from your living room this week.
