Final answer:
The length of the rest period in a HIIT session can vary, typically ranging from 10 seconds to 2 minutes. The rest periods allow for recovery and help maintain the intensity of the workout.
Step-by-step explanation:
The length of the typical rest period between each round of a HIIT (High-Intensity Interval Training) session can vary, as it depends on several factors such as the individual's fitness level, the intensity of the exercise, and the specific HIIT program being followed. In general, rest periods can range from 10 seconds to 2 minutes.
For example, a common HIIT protocol is the Tabata method, which involves 20 seconds of intense exercise followed by 10 seconds of rest, repeated for 8 rounds. This results in a total of 4 minutes of exercise with 2 minutes of rest.
It's important to note that the purpose of the intermittent rest periods in HIIT is to allow for recovery and help maintain the intensity of the exercise. The length of the rest period can impact the overall intensity and effectiveness of the workout.
