Unless Fujino has opted to deviate from the SAO canon in this regard, Inoda has too much stacked up against him, even if he does get into good shape. Kirito comes from a family of martial artists and trained with them for a good while, up until he abandoned kendo in favor of video games. Even then, the reason he could dual wield in the Death Game was because he had the best reflexes of everyone in the game, and a lot of what made him effective in the game was that he could apply his real-world knowledge of martial arts there. While he's let the IRL practice falter, he's still constantly utilizing his martial arts in the game, while also keeping himself decently fit. Inoda's combat experience, both in the game and out, is largely limited to getting the crap kicked out of him.
I also doubt Inoda's going to get particularly physically-fit, because that would require abandoning the Fat Ugly Bastard trope. Also it's going to be hard to suddenly go from "Pillsbury Dough Boy" to "teak-hard abs," and I don't think Fujino will want to make models for each of the transition stages.
), Kirito can canonically fight off IRL a dude using a super-magical-techno-suit that lets him break the bones of several fully grown adults with one arm and move so fast he can ricochet off walls faster than the eye can see, after just like 2 days of training-by-Suguha-through-a-tablet XD
