The physiological benefits of interval training are significant. This training method alternates short bursts of high-intensity activity with periods of low-intensity recovery, leading to improved cardiovascular efficiency and increased metabolic rate. Interval training helps in burning more calories in a shorter time compared to steady-state exercise. Additionally, it promotes improved muscle strength and endurance. Regularly incorporating intervals can also enhance aerobic and anaerobic capacities, leading to better athletic performance and overall fitness levels.
