A workout that features high-intensity efforts followed by short rest periods is known as what type of exercise?

High-Intensity Interval Training (HIIT) is characterized by alternating periods of intense exercise and short recovery intervals. This format effectively boosts cardiovascular fitness, enhances metabolic function, and improves overall performance in a time-efficient manner. The intensity of the efforts activates both aerobic and anaerobic energy systems, allowing for maximal calorie burn and improved conditioning within a shorter duration compared to traditional training methods.

HIIT workouts can include a variety of exercises, such as sprinting, cycling, or bodyweight movements, performed at near maximum capacity. The short rest periods further push the body's limits, promoting adaptations that lead to better stamina, increased strength, and fat loss. This unique structure distinguishes HIIT from other exercise types, making it an effective and popular training choice in fitness programs.
