Yes, indeed.

Martial Arts postulates that dedicated archers can take the Stronbow perk, which adds up to +2 ST for the sole purposes of drawing a bow and additionally three levels of Special Exercises (Arm ST), which allows up to +3 more.

This allows people who might not be freakishly big or otherwise strong, but who can draw a very heavy bow. Such as the people now practising with yew warbows.
