Wouldn't the combat schools, let alone Beacon, require physicals? I'm not saying you're wrong, it's possible. But I feel it's unlikely. More likely he simply doesn't have a lot of stamina, much in the same way that Weiss doesn't. If he's a bookworm then while he might have a lot of skill, he just doesn't use it enough in sustained time periods to build up that stamina. He would have practiced to gain and maintain skill but not for the sheer enjoyment of it like Ruby or Yang would. I feel Weiss is the same way. Combat is a means to an end for her, not something to be enjoyed for it's own sake, like how I think Ruby, Yang, Nora and maybe Pyrrha do. Weiss has a bit more stamina then Ren does I think simply because she's a perfectionist. She would have practiced a lot more before she decided her skill was at the level she wanted.

To the other thing, Ren joining to keep Nora out of trouble, that makes a lot of sense. It might not be quite that one sided, but it's certainly possible, maybe even likely to a lesser or greater degree.
