[Comics] can super heroes work out and increase their strength proportionately to regular humans?

I don’t know how many planets Superman would need to bench to even break a sweat, but assuming he COULD work out, could he get 3-4 times stronger than he already is, the way human weightlifters are roughly 3-4 times stronger than a slob who just sits on the couch?

Like if Peter Parker is a scrawny teen, gets bitten by a spider and can lift 12 tons, can he work out and eventually lift 48 tons? Or does his strength sort of go with his powers, and it just amplified what he had? Like if flash Thompson had been bitten he’d be 2-3 times stronger than Peter-Spiderman but that’s it?

Most of the ones who have some sort of supernatural (as in, they have some sort of powers that give them super-strength, as opposed to someone like Batman or even Captain America whose strength is defined as "peak human" despite usually being shown to be superhuman to some degree) strength don't usually get the benefits of working out to increase said strength, no. Their utilization of their maximum strength gets better through experience, not through any strength training.
