Come to think of it, Praline's current focus on physical training gave Mousse a bit of a headache. The most convenient way to increase the intensity was weighted training, but Praline was simply too strong. She needed at least thirty kilograms of extra weight for it to have a decent effect.
But she was not even seven yet, nor did she have the towering build of Katakuri's Triplet Brothers or even Cracker and his siblings. Even if they used lead blocks, that much weight would be rather cumbersome.
And Praline's strength was growing far faster than her body size. What would they do in another two years?
This also gave Mousse a vague idea of why races and individuals with extraordinarily high starting points shrank as they grew up, even losing the innate advantages of their physiques.
If their training intensity remained too low for too long, the results naturally would not be very good. And the upper limit of physical training effects in the world of One Piece was terrifyingly high—Mousse's strength alone had nearly doubled last year, when his efficiency had been worse than it was now. Over time, others would naturally catch up.
"Gold has a higher density. If I use it to fill training equipment, it should last another year. The problem is, borrowing that many gold bricks from the family won't be easy. After that, I'll probably have to simulate a high-altitude environment and build a low-pressure training room. Didn't Luffy and the others improve greatly on Sky Island? But artificially created low pressure, including low-oxygen environments, has its limitations. It's inconvenient and accidents can happen easily."
Mousse came up with a few ideas, but they could only serve as short-term measures. They were nowhere near enough to keep Praline training until she was fifteen
