[He does lift an arm to pat one bicep. It's not as big as say Katsuki's would be but it's clear that under Izuku's loose-fitting clothing is a lean and athletic body. He's not as scrawny as he might first appear for a nerdy-looking kid.]

So- maybe a wooden sword would be good to start with but I think I'd like to start with an iron one first. One that isn't sharpened?
