Protecting your knees is a big deal. Why do school playgrounds use plastic runways? Plastic runways are widely used in school playgrounds and professional sports training places. The reason is that the plastic track is not only conducive to speed and technology, but also can "shock absorb" and reduce the impact of hard track on knees, even lumbar vertebrae and cervical vertebrae.
Avoid running on cement roads and asphalt roads. Running is beneficial, but it will hurt a knee. In order to protect the knee joints, waist and neck joints and prevent us from falling into various low back and leg pains when we are old, please try to avoid running on hard roads such as cement roads and asphalt roads for a long time. Does the elliptical machine really not hurt your knees? Elliptical machines can also hurt your knees. Any exercise will cause damage to joints, muscles, ligaments and other parts, and any lower limb exercise will also cause permanent damage to the knee joint and knee cartilage. The damage degree of elliptical machine to knee is lower than that of treadmill. High-quality runners can use various shock absorption methods to avoid knee joint injury. But a 10,000-yuan treadmill does more harm to the knee joint than the most common elliptical machine.
