Climb stairs to exercise physical science. When climbing stairs, you must lean forward slightly, including swinging your hands and striding. Only in this way can the number of lower limb muscles and ligaments be enhanced, the flexibility of foot joints be maintained, and the visceral function be enhanced. When climbing stairs, the breathing frequency and pulse rate will be accelerated, which is of great benefit to human breathing, blood system or heart.

In architecture, it is used as a component of vertical traffic between floors. Used for traffic contact between floors and when the height difference is large. Multi-storey and high-rise buildings with elevators and escalators as the main vertical means of transportation should also be equipped with stairs. Although elevators are the main vertical means of transportation in high-rise buildings, stairs should still be reserved for escape in case of fire. Stairs are composed of continuous steps (also known as ladder running), platforms (rest platforms) and enclosure components.
