When running, if the forefoot touches the ground first or the whole foot touches the ground at the same time, it will cause damage to the tibia and knee joint in front of the calf, which will strongly stimulate the calf muscles and thicken the calf; If the running posture is that the heel touches the ground as much as possible, then roll from the heel to the sole of the foot. Running in this way can reduce the pressure on the ankle and avoid injury. When the foot touches the ground, the knee joint remains slightly curved, rather than straight, which has a buffering effect on the knee joint and can stretch the calf, but it does not stimulate the calf muscles strongly. This kind of running won't thicken the calf. When running, we need to use all our leg muscles to jump. Among them, the anterior thigh muscles are mainly used, but the calf muscles are inevitably used. In order to avoid radish legs, you can do some stretching exercises after running to relax tight muscles.

In addition to the correct running posture, the slimming method to avoid calf thickening should also take jogging under low-intensity, rhythmic and long-lasting aerobic exercise to consume sugar and fat in the body. Jog for at least 30 minutes and up to 1 ~ 2 hours. But the speed should not be too fast, the heart rate should be controlled within the heart rate range of aerobic exercise, and it should not be too slow, otherwise it will not play the role of exercise. Jogging for more than 20 minutes can not only exhaust glycogen in the body, but also utilize fat in the body. Because jogging is not very intense, it will not make the body too anoxic, so it will help the consumption of fat, thus achieving the purpose of losing weight.
