HIIT workouts are still some of the most popular for one simple reason: they work! By performing quick bursts of high-intensity movements with all-out effort, followed by short periods of rest, you can torch calories and sculpt lean muscles in a relatively short amount of time.

"One of the big benefits of HIIT is the ability to maximize caloric output during a shorter workout," says Noam Tamir, CSCS, owner of TS Fitness in New York City. "It improves heart health, increases VO2 max and creates more of a post-exercise oxygen consumption or afterburn effect, helping to burn more calories than moderate intensity exercise."

And they're just as effective as longer workouts or steady-state cardio. "A 20-minute HIIT workout can be as beneficial as a 40-minute moderate intensity workout," Tamir says. "Depending on an individual's fitness level these workouts have all shown to build strength, increase muscle mass and burn fat, too."

Want to give it a go? Try this 20-minute HIIT workout from Tamir for a whole series of benefits and a serious calorie burn. It doesn't require any equipment, so it can be done anywhere, by pretty much anyone!

20-Minute HIIT Workout You Can Do Anywhere

Just a few things to keep in mind before you get going on this workout. "Make sure to warm up and cool down," Tamir says. "During your rest period, focus on breathing and shaking out your body to release the tension you build up during the exercise part." And lastly, make sure you're well hydrated, and don't eat too close to training time, he says.
