Stretching exercise is a fitness method, which can make the coordination between ligament muscles and joints softer and reduce the possibility of injury. Including active stretching and passive stretching.
The so-called active stretching refers to keeping the movement in a specific position mainly by the strength of muscle contraction, rather than other external forces. The advantage is that it can increase the flexibility of action and the strength of muscle contraction.
The so-called passive stretching refers to using one's own weight or equipment to keep the limbs in a certain stretching posture. This is a slow and relaxing stretching, which can also be expected to reduce the excitability of nerves and muscles. This is a good way to relax after exercise.

Methods to prevent calf thickening after running
1, heel landing is the key. It is not correct to land on the forefoot first when running. Although it is easier and easier to start running in this way, it will cause thick legs. So remember to land on your heels when running, and then jog with your forefoot on the ground.
2. Warm-up exercise is very important. Since primary school, when I was in physical education class, my teacher taught us to do warm-up exercises before exercise to prevent muscle strain. Therefore, before running to lose weight, we must first stretch the leg muscles so that the calf can meet the following movements in the best state.
3. Jogging is the most effective way to lose weight. Running belongs to aerobic exercise, which consumes excess fat in the body through exercise to achieve the purpose of losing weight. So this kind of exercise needs to be carried out in an aerobic state, and jogging is in line with this state. The real burning time of fat is after 30 minutes of continuous exercise, so jogging for more than half an hour is the most effective way to lose weight.
4. Stretching after running is essential. Many people are in a hurry to buy something to drink as soon as they finish running, often ignoring the stretching link after running. Stretching after running can not only relieve and avoid muscle tension after running, but also effectively keep the leg shape perfect. Therefore, stretching after running is essential.
