This is a problem that needs attention, not how much you walk, but the way you walk! When walking and running, you should first move your hips and thighs to drive your calves and feet. You can't move your feet and calves first, which will really make your calves thicker and uglier. In addition, the walking posture of moving the thigh first is also beautiful, showing high center of gravity, elegance and strength. If you kick the calf first, it means that the heel hits the ground first, the center of gravity is behind, the stomach is in front, and the posture is ugly. You see, many rural old ladies are like that. They look heavy, stupid and not smart. When you are tired from walking and running, the first thing that hurts is definitely your hips and thighs. If the calf hurts first (the so-called hamstring twitch), it is wrong, and it is really counterproductive.
