Both were equally strenuous. I might feel a little sillier swinging the sword, but it's just as hard as boxing. The difference is when you make a mistake in the boxing you just get tapped a little and you shake it off. But with the swords they use real steel. Every actor had cuts on his hands and people get hit on the arms, so it's a little harder.
