i suspect that both upper arms were roughly in line and in compression and the force on both were equal (newton's 3rd law) the spine would remain fairly normal, unless they were also engaged on other heavy tasks that bent them.

heck, richard the third had a bent spine and was a noted warrior and swordsman. as his enemies won, he's had a bad press ever since. the victors write the histories after all...
