Spinning bike mainly sits in the whole process, and the seat bears the main weight. Compared with treadmills, elliptical machines, treadmills and skipping ropes, the damage to the knee joint is very small. It should be noted that the proper position should be adjusted so that the knee joint does not exceed the vertical line of the toe during the whole movement to reduce the injury.

Action essentials and related precautions:

After getting on the bus, the center of gravity should be backward, and the center of gravity should be between the hips and shoulders as much as possible. The trampling action should be even and arc-shaped, and it is forbidden to trample hard. In addition, the soles of your feet should always be level, and don't press your toes down. The front foot is stressed. Note that your knees should be bent during falling, not straight, but there is a buffer for falling.

Don't ride a bike too much a week, just 40 minutes each time, four times, and other aerobic exercises can be interspersed in the middle.
