[DC Comics] How strong is Superman when deprived of his powers?

Say, in Red sunlight. He's still got all that muscle mass. If in a place with the same gravity as the Earth's, would he be fairly strong for a human his size? Is he piss weak despite being built like a brick shithouse?

So, it's slightly complicated. On paper, as you say, he's built like a brick shit house, and all his training and experience as a life long superhero doesn't go away. He'll be far from a pushover. The issue is the change itself.

Like, imagine how you'd react if suddenly everything in the world became a thousand times heavier. This would pretty seriously hamper you- even with things you could still lift, you're not used to having to exert yourself this much, or moving in this situation. You'd be pretty useless for quite a while.

Same here. When superman has an opportunity to get used to losing his powers, yes, he is very physically impressive as humans go and has done legitimate heroism. But when it's a brief or sudden change, he usually collapses. Not so much because he's suddenly weaker, but because he's suddenly so much weaker then he was used to.
