Choose the right sports shoes. Shoes should be soft, with good support, wrapping and comfort to reduce the impact on the knee joint.

2. Control the amount of exercise. If you walk for a long time, whether on the flat ground or on the rugged mountain road, the knee joint is prone to wear. Therefore, in the process of walking, it is necessary to step by step, give muscles and knees a buffer time, stop for 3 minutes every 20 minutes, and take 6,000 ~ 7,000 steps every day to avoid problems such as muscle strain and joint injury caused by walking too much.

3. Keep the correct posture. Hold your head high, your chin slightly convex, your back straight and relaxed, and your shoulders naturally pull back; The knees are straight, the upper body leans forward slightly, the hind legs push to the ground, and the thighs drive the calves; Don't lift your feet too high. The center of gravity gradually reaches the toes from the heel through the sole of the foot. Try to walk straight, with your toes pointing straight ahead, and don't have splayed feet. At the same time, swing your arms naturally and keep a proper walking rhythm.
