Training usually meant that one needed to do it in order to surpass the limit. But That is not the only thing a training can do. Or in this case, it's sparring.
Instead of fighting until one find their own limit then surpass it, what if there's another meaning of training? For example looking for something that they can do, but they don't know yet if they can do it? Learning another strategy? Finding the opponent's weakness?
For some, it might not be considered as getting stronger. But what's the goal of getting stronger? Isn't it so that one can overpower their opponent?
Whether it's to kill someone, to protect someone, because they enjoyed it, or many other reasons, the purpose of getting stronger is always the same. To overpower one's opponent.
