[Isn't her daughter just adorable? It really warms her inside to see how much Bulla loves Vegeta, and she must do so because even without having raised her she already knows the child isn't the "train all day" type. The way Bulla is does nothing but hammer more and more the fact that the Vegeta she knows will eventually change, just a bit and for the better. It works even better than just being with him here, at least Bulma finds it easier to deal with.]

I can't help with making you better at fighting.

But I'm sure I can help you with improving your stamina and endurance. I know you already have lots of that, but I doubt you're on a level capable to train with your father the whole day without ending exhausted and bedridden for days due muscle ache.
