There are warm-up actions such as low-intensity aerobic exercise and static stretching before fitness. Warm-up is very necessary before high-intensity sports training. You can do some low-intensity aerobic exercise or static stretching, which can help muscles slowly open blood vessels, increase blood flow, and let the body gradually adapt to the intensity, thus achieving perfect blood supply. When the body temperature rises to a certain extent, it can reach the core temperature needed for training. Static stretching can effectively prevent the target muscle group from being injured during training.

Warming up is not simply twisting your neck, pressing your waist, stretching your legs, or jumping. By warming up, you can minimize the injury of muscles and joints, especially the fragile shoulder and knee joints. The combination of jogging and dynamic stretching can raise body temperature and heart rate and send a signal to the body that it is about to enter the state, so please make a series of preparations for your muscles.

Warm-up can prepare muscles and keep the brain awake. Trainers with certain experience will relax the body ligaments and make the joints flexible through dynamic stretching and static training. Especially dynamic stretching, repeating an action in a short time, can effectively reduce muscle viscosity and improve toughness. Then, the next series of exercises will become more relaxed and comfortable.
