'abdominal' originates from Latin, specifically the word 'abdomen', where 'ab-' meant 'away' and 'domare' meant 'to tame'.

'abdomen' transformed into the English word 'abdominal', and eventually became the modern English word 'abdominals' as a plural form.

Initially, it referred to the belly or stomach area, but over time it evolved into its current meaning of 'muscles in the abdomen'.
