Running on the treadmill is safer than running on the ground. Running opportunities provide a good shock absorption function. When running, the knee joint bears the greatest pressure on the human body, especially when running on the non-plastic ground. Because the ground is uneven or curved, the pressure on the knee is even greater. Running on uneven ground for a long time will hurt your knees and ankles.
