HIIT, or High-Intensity Interval Training, is a workout strategy alternating between short, intense bursts of exercise and brief recovery periods. Its popularity in fitness programs stems from its time efficiency, allowing individuals to achieve considerable fitness gains in a shorter time frame compared to traditional exercise. HIIT boosts metabolism and can enhance both aerobic and anaerobic fitness. Additionally, it is versatile, accommodating various fitness levels and preferences. The afterburn effect, known as excess post-exercise oxygen consumption (EPOC), allows for continued calorie burning post-workout, making HIIT appealing for those seeking weight loss or improved cardiovascular health.
