What is the main focus of a high-intensity interval training session?

The main focus of a high-intensity interval training (HIIT) session is the alternation of high-intensity efforts with rest or low-intensity efforts. This training method is designed to maximize calorie burn and improve cardiovascular fitness in a shorter amount of time compared to traditional steady-state exercise. HIIT leverages the body's ability to recover quickly from bursts of intense activity, allowing participants to push their limits and experience both aerobic and anaerobic benefits.

The structure of a HIIT session typically involves short bursts of intense exercise, which may last anywhere from 20 seconds to a couple of minutes, followed by periods of reduced intensity or complete rest. This not only increases the heart rate significantly during the high-intensity periods but also promotes metabolism boosts even after the workout session has ended.

Flexibility and mobility training, muscle building, and sustained endurance work represent different goals and methodologies that do not align with the primary aim of a HIIT session. While flexibility and mobility can complement overall fitness, and muscle building can be part of a comprehensive training program, they do not define the core approach and structure of high-intensity interval training. Similarly, sustained endurance work typically involves continuous activities at a steady pace rather than the alternating high-intensity and recovery phases characteristic of HI
