Quads? Hamstrings? The terminology flies over Hiro's head, and he makes a mental note to look it up, or rather, find an educational anime. Why research when someone else has made a waifu out of it? He nods and does as instructed, or tries to anyway. It's a different strain than using his arms, but ultimately he doesn't struggle too much with it. It seems like running around Akihabara every week with loads of junk strapped to any available pocket and backpack space actually helps build some muscle.

"One...! Two...!"
