Ectomorphy is a term which refers to a specific body type that is characterized by a lean, tall and narrow boned frame with a low fat percentage. The term is often used in the context of the somatotype classification system, which categorizes people into one of three types - ectomorphs, mesomorphs, or endomorphs. Synonyms for the word "ectomorphy" could include "slender built", "lean frame", "thin-boned", "skeletal build", or "skinny physique". Alternatively, "ectomorphic body shape", "lanky figure", "narrow body type" or "long and lean" could be used to describe a person with ectomorphic characteristics. Whatever term is used, it is clear that the ectomorph's body shape is unique and can have a significant impact on their health and fitness level.
