2. Another thing is that some people are used to walking inside the eight characters, and the same is true when running. Running or walking in a figure of eight for a long time is easy to make the legs form an X-shaped leg shape, resulting in calf obesity.
3. In order to run lighter and faster, some people will touch the ground with their toes when running. This is also wrong, which will cause their legs to deform and their calves to thicken.
4. Don't lean forward and lean back too much during running, which will lead to diseases and deformation of the back and some diseases of the spine.
5. Choose comfortable, light and elastic sports shoes when running, and don't run too fast. It is best to jog and do stretching before running.
