At present, with the improvement of people's fitness awareness, climbing stairs, which is both economical and convenient, has been welcomed by many citizens. Experts pointed out that climbing stairs is also exquisite and good for your health, but it is not good to go downstairs.

According to experts, going upstairs is equivalent to doing aerobic exercise, which can exercise heart and lung function and leg muscles at the same time, which can play a certain exercise effect. But when going down the stairs, the knee joint and ankle joint should bear the weight of the whole body. Repeating this action will artificially increase the mobility of these joints, the intensity of compression will increase sharply, and the possibility of joint wear will increase, which is not good for the body.
