Short for latissimus dorsi, the large, flat muscle of the back that extends from the spine to the upper arm bone. Often referenced in fitness and bodybuilding contexts.
Abbreviated from Latin 'latissimus dorsi' meaning 'broadest of the back.' The full anatomical term was coined in medical Latin, with 'latissimus' being the superlative of 'latus' (wide) and 'dorsi' being the genitive of 'dorsum' (back).
The lats are among the most visually impressive muscles when developed, creating the coveted V-shaped torso in bodybuilding. These muscles are evolutionary remnants from our tree-climbing ancestors, explaining why pull-up movements feel so natural despite modern sedentary lifestyles.
