The potential benefits of high-intensity interval training (HIIT) include improved cardiovascular fitness, increased fat loss, and saved workout time. HIIT involves alternating between short bursts of intense exercise and rest or low-intensity periods, which can lead to greater calorie burn in a shorter period. This training style boosts metabolism even after exercising, promoting ongoing fat loss. Additionally, HIIT can enhance muscle tone and improve overall endurance, making it an efficient and effective fitness strategy for busy individuals.
