If you did not attend a workout yourself, you probably heard at least intensive interval training (HIIT). And there's a reason why HIIT workouts are so popular - science proves they work.
High Intensity Interval Training (HIIT) is rapidly becoming one of the most popular forms of cardiovascular exercise. As the name implies, these are intervals or short periods of intense training, followed by short rest periods in a cycle or cycle.
HIIT stands for high intensity interval training. In essence, you alternate short periods of very intense exercise with periods of recovery. The recovery can be a full break or, for many workouts like this one, an active recovery that still keeps you moving, but at a much simpler pace.
HIIT is an abbreviation for "High-Intensity Interval Training", which refers to a training technique that combines hard efforts with short rest periods. The term "HIIT training" is a colloquial term for HIIT training sessions. However, pronouncing all the words in the acronym would result in cumbersome redundancy ("high intensity interval training").
