Multi-functional treadmill design
Nowadays, many urbanites are busy with work, and they have less and less time for outdoor activities, which are also limited by the environment and weather. Many people use treadmills instead of outdoor exercise for the convenience of fitness. The treadmill is the fitness of choice for more and more people. Running on a treadmill is safer than running on the ground. The running machine provides good shock absorption. The knee joint experiences the greatest amount of stress on the body during running, especially on non-plastic surfaces, with more stress placed on the knee due to uneven or curved surfaces. Running on uneven ground for a long time can lead to knee and ankle injuries.
