I do agree with Rhyhorn scaling being wack, especially since its hurt when it crashes into a steel block.
IMHO, this isn't the best reasoning. It's a "may" feel pain.
Not to mention, I'm concerned that in this particularity, you may be misrepresenting &/or misremembering.
| Ruby | Rhyhorn runs in a straight line, smashing everything in its path. It is not bothered even if it rushes headlong into a block of steel. This Pokémon may feel some pain from the collision the next day, however. |

Rhyhorn is stated to not be bothered by rushing headlong into the block of steel, and MAY feel some pain from the collision the next day.
Low-end showings are a thing, & when considering Pokedex entries, it has many feats higher than that.
IIRC, we take things at their best. Characters like Spiderman can get bowled over by the equivalent of a rock being thrown at them when they can lift busses, Kirby being hurt by any of a myriad of environmental hazards, etc. There are lots of low feats, but the high-ends exist, too, & we shouldn't dismiss high-ends just because low-ends exist when this kind of contrast exists in basically every series. We'd need other evidence affirming the high-ends are contradictory. Not to mention, the low-ends could be called contradictory, for similar reasoning.
Even if this isn't a low-end showing, I'd dare call that Plot-Induced Stupidity.
That whole scene is from an episode where Goh trained a Magikarp to win a jumping contest, & it's where the infamous Magikarp jumping into space clip comes from.
The Machamp struggling with the weights is likely to emphasize the sheer mass of the training weights removed from Goh's Magikarp. I'd call that visual hyperbole, because although the shape would be awkward to calculate the mass of, there's a part of me that'd be confident in saying both previous members of Machamp's evolutionary line have feats that should yield higher mass than those weights.
Either way, the notion those weights have more weight than what Machamp can lift, going by its other feats, is to be ridiculous, & given their context in the episode (To shockingly reveal how intensely Goh trained the Magikarp, as was central to that episode's plot.), again, I'd call it Plot-Induced Stupidity &/or visual hyperbole.
Pardon the wordyness, please, all.
