What is the main objective of interval training?

The main objective of interval training is to alternate periods of high intensity with rest or low intensity. This training method is designed to enhance cardiovascular fitness, improve endurance, and boost overall performance by varying the intensity of exercise. The inclusion of high-intensity bursts followed by recovery phases allows the body to adapt to different levels of exertion, leading to improved metabolic efficiency and increased calorie burn during and after the workout.

By incorporating intervals, participants experience periods of exertion that push their limits, which can lead to greater improvements in fitness levels compared to steady-state exercise. This variability not only keeps the workouts engaging but also helps prevent plateaus in physical performance. When considering the other options, they focus on single aspects of fitness or maintain a constant level of exertion, which does not capture the dynamic nature and primary goal of interval training.
