Hiit is an aerobic training, and the training time is usually 4-30 minutes. Its core idea is the alternation of high-intensity training and low-intensity training in sports.
Hiit's fat-reducing principle is different from aerobic exercise. Low-intensity aerobic exercise consumes fat directly, while in Hiit training, fat is not burned, but burned.
Hiit in the whole exercise process, the main energy supply is not fat The significance lies in improving the static metabolic rate 24-72 hours after the end of exercise, which leads to fat decomposition due to accelerated metabolism, thus achieving the purpose of reducing fat.
The advantage of Hiit is obvious, that is, high efficiency, and the fat-reducing effect brought by general intensity Hiit for half an hour will be very considerable. Compared with aerobic exercise, it often takes an hour to face it, which greatly saves time. The side effect of Hiit is that it also breaks down muscles.
Hiit is suitable for non-bodybuilding, because its high metabolism can be maintained for a long time after strength training, and it is not necessary to use Hiit to improve metabolism. Moreover, in order not to lose muscles after strength training, it is more suitable to use oxygen with low heart rate, while Hiit is not feasible to achieve high heart rate by consuming muscles to improve heart rate.
Hiit is a problem for people who lose weight only by non-strength training. On the one hand, its training intensity needs people with a certain foundation to complete. On the other hand, people who don't train often have a heavy heart load and can't stand it. Non-professional athletes often make their hearts reach a high heart rate. If the heart is not very good, people are prone to myocardial strain and inflammation, so jogging is safe and effective.
