What does HIIT stand for?

The term HIIT stands for High-Intensity Interval Training. This method of exercise involves alternating short bursts of vigorous activity with periods of lower-intensity recovery or rest. The high-intensity segments push the body to exert maximal effort, which can lead to increased cardiovascular fitness, improved metabolic rate, and enhanced calorie burning in a shorter amount of time compared to traditional steady-state workouts. The structured intervals allow for effective training within a limited timespan, making it an appealing option for those with busy schedules.

Understanding this training modality is essential for fitness professionals as it is widely used in various workout programs and has been shown to yield significant health benefits. The other options are variations that do not accurately describe this widely recognized training approach, which focuses on the specific technique and science behind the workout design.
