Hm. So resistant up to 10x gravity, then? Anything else?
Edit: Wait, this makes no sense, as Goku was not naturally capable of resisting 10x Gravity thanks to his heritage-Implying that it actually isn't a built in physiological capacity. (This is especially relevant, given Kid Goku was able to train in the HTC for a Month, meaning it's not just IRL decay/detoriation that we see in Zero G being applied to Goku. Also, like astronauts, who work out every day to completely mitigate this, Goku was constantly pushing himself physically, so he shouldn't have had any issues, and with the RoSaT he'd have experienced 10x Earth's Gravity, and yet still wasn't prepared for it on King Kai's planet. Though, it's probably an oversight on Toriyama's part.)
Edit 2: Also, King Kai says Saiyans are
"strong due to their environment," and that's "...Not even mentioning their inborn fighting instincts." This is then directly juxtaposed by
Goku mentioning his own Saiyan Heritage. So it seems pretty clear that Saiyans don't just naturally have 10x gravity resistance.
