Thank you for adding something new to the conversation, i was getting tired of refutting Rea, i felt like i was dealing with the one drawing and was about to quit since the last thing i have to check to back me up was the novels and for me that's too much effort to win an internet argument.
uh, so at least in the anime she officially had to have physical training to increase her chakra enough after starting making the seal not to fall uncounscious in minutes.
I followed the story through the manga, so I would not have known.
I usually favor the manga for info like this, but as we hopefully will get some hot anime filler girls here...
Tsunade and Sakura's strength is actually an odd thing. as far as the mechanics of the series go. Technically, they're not actually supposed to be particularly strong per se, and their ability to punch people through (multiple) buildings is supposed to be a result of extremely well-applied use of chakra. I could go into the mechanics behind it, but the short answer is that it's like the fuckup tree walking attempts from the Wave arc, only much more concentrated and done intentionally (and requiring much, much, much more control). But that only explains their ability to ONE-PUUUNCH! things, and we repeatedly see the both of them doing things that aren't explained by impact physics and the above technique.
So either A: they have some sort of unmentioned technique that allows them to somehow lift objects that are much heavier than their muscles would be able (very possible, actually, and I even have an idea of how such a thing would work based on the rules of the series)
B: they use something like the first of the Eight Gates constantly and just have an automatic medical jutsu running to instantly heal all the micro-scale damage that using 100% of your body's strength would cause (also quite likely, possibly even more so than option A)
or C: they really are physically strong enough to lift things that heavy, and the punch thing is just an extra bit they add on top of it (the least likely option, being that it would make the punch much less impressive, and also take up so much more time to maintain, the exact opposite of the above technique).
Or D: Kishimoto forgot the explanation he gave for Tsunade being able to punch through walls despite being a retired 50+-year-old woman, and accidentally gave her unexplained super-strength.
Actually I think she had retarded super-strength before the explanation was given. wasn't it given to explain Sakura's superpunches while on her first battle Tsunade could lift Gamabunta's giant sword?
Some years ago on a fanfiction forum it was said that showed Tsunade had natural super-strength, while Sakura neededthat trick.
But thinking about it, I think it is B together with C - less impressive C may be, but adding more power to a super punch is still an even stronger super punch.
B would explain Tsunade's youth power, and how she ages so much more than she should when it goes of: it is a gate-like medical flow through her body, both strengthening and healing her to keep her young. But that means when it stops she is not just on 0, but is on deficit, and whatever was damaged right before then stays damaged - thus seems older.
Kishimoto can sometimes skip the details, OG Naruto had Rock Lee, a taijutsu-only user that looked petty scawny, doing things that pale in comparasion to what the rest of the cast have done before, then he takes his weights off and his speed and strenght increases a lot, even before opening the first gate, while still looking like a teen that can't lift even a ton, let alone wear ridiculous weights that are so heavy, you might as well think that someone blew two bombs or dropped two boulders high enough to reach terminal velocity.
It's rumored that Tsunade is so ludicrously strong because Senju bloodline
By the way the healing jutsu's forcefully regenerate the body of the patient, potentially saving their lives in exchange for decreasing the life-spawn in a nutshell, at least the regenerative ones.
From what i can get from the wiki the rest of the medical skills are infusing chakra into others to protect them, to force the heart to keep beating and to use her hands as every medical tool.
The chakra control training that i saw was storing most of her chakra
by meditating, learn to produce more chakra
by training, using her hands as knives, low-key fibrilators, etc.
post training/Shippuden.
The medical training that i saw was basically reading books, a lot of medical books.
It would also make sense that Tsunade trained Sakura in raw strenght considering that Taijutsu doesn't require chakra
Unless Tsunade injected Sakura with Hashirama cells
The nanomachines of the Naruto universe and that means...
On another note, while attempting to find evidence of Sakura being trained to increase her physical strenght i found a video which either explains or states that Sakura is as strong as non-six path Naruto and i find that as quite the outlandish leap, considering that Naruto harbors Kurama who can go toe to toe with KillerB despite only being the Yang/Half-Kurama, then he can go Kurama/Nine-Tails Chakra Mode and stack it with Sage mode, so, making Sakura so inherently strong would not only shit on Naruto, Sasuke and the tailed beasts but also on Mighty Guy, the strongest Taijutsu user alive
Madara's words.
