First, look at the tips of your running shoes. Are they badly worn out on the outside or on the inside? According to the wear and tear, the second is to correct the running posture. Running on the treadmill for a long time and keeping the heel on the ground is good. You go to the marathon. That's what all those people do. (As a result, your legs get thinner.) When you run, you have to feel like a ball with your feet touching the bottom of your heel, then stick to the ground and roll to your toes. Fine experience, the damage to your feet is the smallest last, step problem. Running makes you feel your calves are stretched, and that's the right pace. Remember, after running, you must stretch the leg muscles. The result of stretching relaxes your muscles. The next day, the muscle fibers are stretched and the legs become thin and slender. Without stretching, the next day may be painful, and the thicker the legs are, the more I experience. I spent several years in the gym. The coach said that it's good to master the basic methods, which are suitable for me. I hope you can stick to it.
