What are you talking about? Nobody said anything even remotely related to muscle memory or body conditioning.
King Leonin said he doesn't like Naruto using RS mode, and that he'd prefer if he only used it if he had no other choice. His specific words were "After Naruto used up all his Chakra".
I was just explaining that it's takes chakra to trade with the fox for it's chakra. So if Naruto doesn't have any chakra he can't use RS mode anyway. What's more, it was explained that once the fox has used up all naruto's chakra, he'll take over his body and be set free. Therefore going RS mode is not only impossible with no chakra, but even trying to do it will kill him. What's so hard to understand about that?
