The type of training that involves short bursts of intense exercise followed by rest is known as High-Intensity Interval Training (HIIT). HIIT alternates periods of maximum effort with active recovery or rest, maximizing the efficiency of workouts in a shortened duration. This approach improves cardiovascular fitness, burns fat, and boosts metabolism. HIIT is also time-efficient, making it suitable for individuals with busy schedules. Furthermore, it can increase muscle strength and promote mental toughness, contributing to overall fitness and well-being.
