Lately, the fitness buzz has been all about high-intensity interval training, or HIIT. Many people find it more fun than steady-state cardio, and research shows that it’s more effective at torching calories and burning fat. This means that HIIT is a better and more effective way to get a toned physique than spending hours on a treadmill.

So what exactly is HIIT? HIIT is a training style where you work out at a high-intensity for a set amount of time, then take a short rest period before repeating the process. Usually, you’ll repeat one move as many times as you can for a 20-30 second period. Take a short break to catch your breath and do it again.
