That doesn't have anything to do with Aura tho. It hasn't been properly established that your Aura's size is what defines how many hits you can endure or how much your physical abilites are enchanted. It could all depend on how much you've trained your Aura instead like how Ren can't endure much damage but his defenses and abilities are super strong. His Aura is smaller but far stronger so Jaune having a large aura isn't necessarily what makes him  physically fit. It could all just be a product of training. Jaune has always been very strong even before being properly trained.
