What does "HIIT" stand for?

The term "HIIT" stands for High-Intensity Interval Training. This training protocol is characterized by short bursts of intense exercise followed by rest or low-intensity periods. The primary focus of HIIT is to maximize effort during the work intervals, allowing for improved cardiovascular fitness, increased metabolism, and enhanced calorie burning both during and after the workout.

HIIT has become popular due to its efficiency, often requiring less time than traditional workouts while still delivering significant fitness benefits. The correct terminology emphasizes the high intensity of the intervals and their structured nature, which is a crucial aspect of this training method. Understanding this definition is important for anyone studying fitness and exercise programming, as it encapsulates a widely used technique that can be adapted for various goals, whether it's weight loss, endurance training, or performance improvement.
