When physical strength hits it's limits?

[GSM123]

There’s a limit to physical strength, no matter how much you toughen it up, and the only way to overcome that it is with “ki”.

So, according to Toriyama, there's a point your physical strength hits a wall. But when did that happen? By the begining of the Boo Arc, Goku is still doing weighted training, and later on Gohan even surpassed his father by doing muscular training (Swinging the Z Sword around).

I don't know if anything contradicts it, but I always thought stuff like the weight training and the Z Sword training was still Ki training since the Z Fighters use their Ki to amplify their physical strength.

I'd think the weighted training from Goku is like a warming up to keep his muscles in shape, but Gohan getting stronger by swinging the Z Sword around is definitely something weird. It's probably something related to muscular memory, though if Gohan only recovered his CG power with the Z Sword he'd still be weaker than Goku, what's not implied.

Not only GT, but everything from :toei
