Don't care too much. For fitness white, it is best to run with small steps and high frequency to prevent yourself from running off course. Speed and time. We know that the human body has slow muscles and fast muscles. Slow muscle is slender, slow in contraction and weak in strength, but it has good endurance and strong oxygen transport ability, and can also transport waste more effectively. When we do endurance sports, such as jogging, the main function is to slow down the muscles and not make the calves fat.
Muscle fat is fast, contraction is fast and strength is great, but endurance is poor and aerobic capacity is weak. Suitable for explosive sports, for example, when we do 100 meter sprint, it is mainly the operation of fast muscles. By comparing the figure of sprinters, we can find that sprinters are strong, with strong thighs and corners. Long-distance runners are generally thin and have slender legs. Therefore, if you want to slim your legs, you can't sprint at extreme speed, but jog at a more relaxed speed for a long time.
Stretch. When running, our muscles are contracting. If we don't stretch often, our muscles may become thicker and shorter. Over time, our legs will become thicker and sharper. Here are a few stretching exercises to pull the calf out of the leg: running rubs the leg and hurts the knee is the biggest problem, but it is not caused by running itself. We should study more and learn to run correctly instead of running blindly. Running seems simple, but you still need to know a lot to run well.
