Aerobic exercise refers to the physical exercise carried out by the human body under the condition of adequate oxygen supply.

That is, in the process of exercise, the oxygen inhaled by the human body is equal to the demand, achieving physiological balance.

Sports, an activity involving physical strength and skills, is bound by a set of rules or habits and is usually competitive.

There has never been a cosmic movement in time and space, and the cosmic movement has given birth to everything.

There is no object that does not move, and there is no movement that can leave the object.

Movement is conservative, that is, it can neither be created nor destroyed, but its concrete forms are diverse and can be transformed into each other, and the total amount of movement remains unchanged during the transformation.

In geometry, the motion of a rigid body is described as the mapping from a plane to itself, and the distance between any two points A and B is the same as the distance between their images A' = m (a) and B' = m (b). In philosophy, the definition of motion is the linear migration of things in time and space.
