Which training method focuses on alternating high-intensity work with recovery?

High-Intensity Interval Training (HIIT) is recognized for its unique approach of combining short bursts of intense exercise with periods of rest or lower-intensity activity. This method is highly effective for improving cardiovascular fitness and burning calories in a shorter amount of time compared to traditional steady-state training. HIIT typically involves performing an exercise at maximum effort for a specific duration, followed by a recovery phase where the intensity is reduced, allowing the body to partially recover before the next high-intensity segment begins.

This type of training is beneficial for athletes and recreational fitness enthusiasts alike, as it can enhance endurance, build speed, and promote better fat loss. The alternating pattern of exertion and recovery not only keeps workouts engaging but also maximizes the efficiency of workouts by pushing the body's limits and promoting adaptations that enhance overall performance.

Other options, like fat burning training and continuous training, do not involve the same level of intensity alternation found in HIIT, while strength training primarily focuses on building muscle strength rather than alternating high and low intensities for improving cardiovascular health.
