The focus is on high intensity and starting the next set of exercises before the physical strength is fully restored.
Simply put, it is a high-intensity exercise that stops to rest.
In fact, jogging and swimming on the treadmill are not suitable for HIIT because the intensity is not strong enough.
The principle of HIIT is to improve the utilization rate of oxygen, thus increasing your resting metabolic rate. In fact, in aerobic exercise lasting more than 30 minutes, oxygen only increases in the first few minutes, and the metabolism of the body is maintained in a stable state, and HIIT will make your oxygen absorption at a higher level in these ten minutes. Thereby improving your resting metabolism level.
There is also the fact that fast muscle fibers (explosive power and strength) use less heat than slow muscle fibers (endurance), so when you do the same action, fast bursts will consume more heat than slow bursts. So sprinting 100 meters will consume more calories than walking 100 meters and jogging 100 meters.
So to some extent, anaerobic exercise is better than aerobic exercise in reducing fat. Because of high efficiency.
But aerobic exercise can last longer than anaerobic exercise.
If you really want to run in the HIIT way, it's an interval sprint. You can refer to Tolek's training method. Personally, I don't think treadmills are suitable for HIIT. Or run on the runway.
In fact, HIIT is very simple. A video and an open space are enough. No equipment is needed at all.
In fact, the classic fitness plan can also be changed to HIIT, that is, to start practicing the next set of movements before the physical strength is fully restored. Then change the exercise plan of practicing only one muscle at a time to practice all the muscles of the whole body. Because the more muscles involved, the more glycogen and fat you need to use, and the more calories you consume.
The key to this change is that after you practice one set of musical instruments, you will immediately practice another set of musical instruments, and you are not allowed to stay in the middle. These few seconds of walking are your rest time.
For example, after doing a set of bench presses, you go to the chest pliers machine to do a set of chest pliers, then go to the squat rack to do a set of squats, then do a set of pull-ups, and then go to the rowing machine to do a set of rowing. ...
In this way, the muscles of the whole body will be retrained.
