Muscle training:
Muscle fibers control every movement, from blinking to smiling. Thousands of tiny fibers are assembled into muscle bundles, thus forming a complete muscle system. Take rock climbers as an example. Every step of climbing requires the elastic expansion and contraction of muscles. Muscles can only be pulled, not pushed, and most of them belong to skeletal muscles. They are connected by tendons and bones, and the closely combined tendon fibers have the function of rubber bands.
Muscles can affect the eyes, so that we can see things clearly, blink and blink; The muscles of the hands and fingertips enable us to hold very small objects. Take rock climbers as an example, they need to hold something to fix themselves, and continuous muscle contraction can keep them climbing.
