HIIT interval training, its core meaning is: high difficulty and short rest. It is a kind of training that combines aerobic and anaerobic exercise by crossing low-intensity exercise with high-intensity aerobic exercise, or taking a proper rest, but you can burn fat quickly without any instruments and tools, so as to achieve the purpose of reducing fat and weight.
However, obese people with a large weight base are not recommended, and fitness whites also need to be cautious, because the body may not be able to adapt to such intensive training, and the sequelae may be physical pain, joint injury or training failure.
Extended data:
This technology can increase the heart rate and burn more calories in a short time. "High-intensity exercise increases the body's demand for oxygen and produces hypoxia, which causes the body to need more oxygen during recovery."
This kind of exercise leads to excessive oxygen consumption after exercise. This is why high-intensity exercise helps to burn more fat and calories than ordinary aerobic training and steady-state exercise.
HIIT's short-term high-intensity training can better stimulate fat burning and consume a lot of calories for people who are used to ordinary exercise intensity. It consumes a lot of calories, but it has certain requirements for the foundation of exercise and fitness.
