That's the thing about DBZ, the feats really just don't make sense. There's no consistency, the fights are literally rule of cool.

One second we've got people trading blows sending shockwaves across the universe that threaten its very existence, the next, it's a mundane looking fight on a rooftop where stray attacks maybe break a few blocks apart.

Then we've got people cutting through dimensions and fusing with the multiverse, and a little bit later normal bullets are suddenly causing Goku pain.

Blasts that explode so massively that the blast radius appears to be larger than the solar system, good thing they just barely missed and flew off the planet. Next blast hits a rock and leaves a small crater.

Piccolo can blow up the moon in season 1... goku struggles with a few measly tons on his arms while he's working out. At goku's current power level, working out should be completely meaningless because he can't put enough stress on his body to actually get a work out, but he's still putting on heavy suits and walking around and whatever.
