brawny

This term emphasizes physical bulk and raw power, often evoking the image of a heavy-set, muscular frame. It carries a connotation of ruggedness and strength that is more about size and mass than lean, athletic definition.

While similar to words like muscular, it specifically suggests a certain thickness or heaviness of build. It is typically used in a positive or neutral sense to describe physical capability, though it can occasionally imply a lack of refinement or grace.
