Question

why do we tired on quick exercise

Answer 1

During exercise your muscles work hard to lift a load. Whether it be resistance training or aerobic exercise, your muscles are under siege. Your body’s neural response to this load is to recruit muscle fibers to complete the task, but muscle fibers become tired rather quickly. This is due to muscle tissue’s main source of energy, called adenosine triphosphate, or ATP. As your muscles use up this energy source, they become tired and fatigued.
