What characterizes High-Intensity Interval Training (HIIT)?

High-Intensity Interval Training (HIIT) is characterized by short bursts of intense exercise followed by recovery periods. This form of training effectively combines high-intensity work with rest, allowing for improved cardiovascular fitness, increased metabolic rate, and better calorie burn in a shorter amount of time compared to traditional steady-state exercise. The intense intervals push the body to perform at near maximal effort, while the recovery periods enable partial recovery, which allows individuals to maintain high intensity during subsequent efforts.

This method of exercise is not based on consistency at low intensities or steady efforts, nor does it involve long, uninterrupted sessions like traditional long-distance running. Instead, the alternating periods of high intensity and recovery make HIIT a unique and efficient way to build both aerobic and anaerobic fitness.
