High-intensity interval training (HIIT) offers numerous advantages, including increased cardiovascular fitness, efficient fat burning, and improved metabolic rate. HIIT workouts alternate short bursts of intense effort with periods of rest or low-intensity exercise, making them time-efficient and effective for fat loss. Additionally, studies indicate that HIIT can enhance muscle endurance and strength gains. The varying intensities also keep workouts engaging, making it easier for individuals to maintain regular exercise routines and achieve their fitness goals.
