How many calories do you burn with HIIT?

Answer 1

The amount of calories you burn with ANY activity (HIIT included) depends on how intense the activity is, your current weight, as well as the duration of said activity.

HIIT is an exercise protocol, not an activity in itself. You could do HIIT sprinting, swimming, or even going up the stairs. Each of these activities will have a different caloric burn - which will differ for each person, depending on their own, individual stats - broadly, your weight, but again, it is not as simple as that. Moreover, the third factor, duration, is equally important.

Generally, since HIIT is really intense, your body burns extra calories even after you have long finished your workout - this is called EPOC, or "afterburn effect". So, there is that as well to track.

Thus without further information, I can only give you estimates. In general, HIIT is going to burn more calories per minute than less intense activities like brisk walking and jogging. However, maintaining that level of intensity for long is extremely hard for untrained people or novice trainees.

At the end of the day, caloric manipulation is much more easily achieved through diet, whether your purpose is gaining or losing weight. HIIT should be used sparingly, and for reasons other than its caloric burn. Namely:

• Conditioning, where it excels.
• Hormone optimization, which it promotes.
