High-intensity interval training is the term given to intense, short bouts of intensive exercise followed by a brief rest period. It’s fast enough to allow the heart rate to diminish but not enough to offer complete relief from the intensive bout. There is a reason for this, which we will go into.
Keeping it sustainable allows your body to accelerate its caloric burn for as much as a day or two after the workout. This is why HIIT is only taken on for short periods (about 20–25 minutes) and is best kept separate from any other activity within that day (unless you are training twice a day).
It’s so much more effective and time-efficient than jogging for hours, which would usually require quite a lot of time and effort. With HIIT, you can get in the gym or perhaps outdoors and do your thing.
You are not only subject to hill sprints or sprinting on your bike; you can use weights as a means of creating a perfect environment for HIIT. Not only will you get the benefits of burning those stubborn fat stores, but you will also reshape and strengthen your body in the process. This is very similar to circuit training. The difference is you do pay a large amount of attention to form, mind & muscle connection and the regular speed of the repetitions. This may sound like a mouthful, but think of it as your normal weight…
