What is interval training?

Interval training is defined as a style of exercise that alternates periods of high-intensity efforts with periods of rest or lower-intensity exercise. This training method is effective for improving cardiovascular fitness, increasing anaerobic and aerobic capacity, and burning calories in a shorter amount of time compared to steady-state exercise. The high-intensity bursts push the body to work hard, improving overall performance, while the subsequent rest or low-intensity phases allow for recovery before the next high-intensity effort. This pattern not only makes workouts more efficient but also more engaging, as it often incorporates a variety of exercises and intensities, preventing monotony.

In contrast, other training methods either focus solely on one aspect of fitness, such as flexibility or continuous moderate exercise without variation, which does not implement the strategic bursts of intensity that characterize interval training. The nature of interval training allows for a comprehensive workout that can be tailored to various fitness levels and goals.
