What is the primary focus of interval training?

The primary focus of interval training is to switch between high and low intensity for specific intervals. This training method is designed to improve both aerobic and anaerobic fitness. By incorporating periods of intense activity followed by rest or low-intensity recovery, interval training allows individuals to push their limits during the high-intensity segments while also allowing for recovery, which can enhance overall cardiovascular health and increase calorie burn. This approach can lead to greater fitness gains in a shorter amount of time compared to steady-state exercise.

In contrast to continuous low-intensity efforts, which are beneficial for endurance, interval training emphasizes varied intensity, making it effective for increasing speed and power as well. While endurance can be a focus in other training styles, interval training specifically targets improvements through bursts of effort. Additionally, maximizing strength typically involves exercises that engage muscles through resistance more than varying intensities, which is not the central premise of interval training.
