The Perfect 20-Minute 3 Interval HIIT Workout You Can Squeeze in Anywhere For Maximum Gains

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 maximise caloric output during a shorter workout. It improves heart health, increases VO2 max and creates more of a post-exercise oxygen consumption or after burn 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. Depending on an individual’s fitness level these workouts have all shown to build strength, increase muscle mass and burn fat, too.
