First of all, we need to know what high-intensity interval training is. This is an explosive training method, which can make the body exert its full strength in all kinds of rapids. It can make your body consume a lot of energy in a short time and accelerate your heart rate and blood circulation. By increasing the intensity of exercise and reducing the rest time between groups, your body can participate in exercise to the maximum extent.

Then why do we do high-intensity interval training? More and more young people work in the office from morning till night. They face a lot of work every day and have little time to exercise, but they want to stay healthy or have a good body. Therefore, this training mode which takes less time but consumes more energy is very popular. Regular training can not only burn a lot of fat, but also give our heart and lung function a good exercise.

Pull-ups, this action can make our whole upper body get a good exercise, especially the muscles of the back, chest and arms. Of course, the most important thing is to improve the metabolic rate of the whole body and let the fat burn. Then hold the horizontal bar tightly with your palm forward, and then pull your body up and naturally hang in the air. Use the strength of the back to drive the arm to continue to pull the body upward until the chin is at the same height as the horizontal bar, then slowly put it down and return to the starting position.

Sit-ups, don't underestimate that this is not a complicated push-up plus vertical jump. Compared with doing push-ups alone, you can almost reach most parts of your body and make your whole body circulate quickly, so you are more tired than many actions. The first thing is to sit down and support your body, complete standard push-ups, then take back your legs and jump up with the strength of your arms to reach the highest place. Then, repeat the previous operation.
