Apparently, humans are about the only species that need to train to grow muscle, most grow muscle endogenously. Barnacle geese, for example, laze around all day eating, then when it's time to migrate 2700 miles they spontaneously grow muscle when hormones are triggered by the change in daylight hours. Similarly, silverback gorillas grow their muscle when hormones are triggered by becoming the dominant male.
