@Jasonsith: That's not all that trumps pushing those boulders. (Although, my timeframe & sizes are based on estimates, so it's possible it's different. For all I know, there could be calculations of it that already exists.)
"Machop's muscles are special—they never get sore no matter how much they are used in exercise. This Pokémon has sufficient power to hurl a hundred adult humans."
"With its superhuman strength, it's able to throw a hundred people all at the same time. Its strength comes from lifting Graveler every day."
Unless those two entries are somehow talking about two different feats where the second refers to throwing one hundred people who are all children or teenagers rather than adults, it's all but stated outright that Machop can throw 100 adult humans, ALL AT ONCE.
We don't know how far, nor high it can throw them, but it does say it "hurls" them, which means with force, or as a noun meaning a throw, it is especially a violent throw! This is no small feat.
https://en.wikipedia.org/wiki/Human_body_weight#Average_weight_around_the_world
Even if you use the very lowest average, Bangladesh's 49.591 kg, Machop can still throw several hundred kg of humans (AT LEAST) more than those boulders may weigh!
>Machop has a better LS feat than Ride Pokemon Machamp moving that boulder.
Machop is also noted as being able to throw a number of Geodude at once, & easily hefts Graveler; It uses Graveler like barbells.
....But Geodude weighs only 20 kg, about the same as a 6 year old human girl.
Also, an armless, sphere of granite (Or other stone, as many have density near 2700 kg.) 0.4 meters (Geodude's listed height.) in diameter would likely weigh over 91.8 kg. (Because of the mass of the uncalculated arms.)
Graveler only weighs 105 kg. (& Golem, while not mentioned in Machop's line's entries, weighs 300 kg.)
& Machoke gets involved, too! Not just because one of Machoke's feats is made a joke by its pre-evolution throwing 5000+ kg:
"MACHOKE's thoroughly toned muscles possess the hardness of steel. This POKéMON has so much strength, it can easily hold aloft a sumo wrestler on just one finger." (Both this & Machop's first "throw 100 human entries" are from Ruby, too!)
For comparison, the heaviest real world sumo ever is a pitiful 265 kg.
Maybe it's the sumo being held on the area of one finger that makes it impressive?
Thankfully, Machoke has the excuse of wearing a power limiter belt & having a better feat:
"It can lift a dump truck with one hand. Using that power, it helps people with heavy jobs."
"It happily carries heavy cargo to toughen up. It willingly does hard work for people."
Those, among other entries tell us Machoke is very much able & willing to lift heavy things, & the heavier the better. So how heavy is a dump truck, loaded, & unloaded?
It varies, as vehicles do, but results include:
"Light weight (without any material in it): Approximate 28,000 lbs." &
"EMPTY WEIGHT 24,200 pounds. 27,000 pounds is about normal on a Mack with a steel bed."
1 lb = 0.45359237 kilograms, so 24,200 lbs = 10,976.9354 kilograms. Already more than double what Machop is throwing, & one-handedly!
"Typically, a "dump" truck will weigh (when loaded) between 12,000 to 74,000 pounds."
"Federal law controls maximum gross vehicle weights and axle loads on the Interstate System. Federal limits are 80,000 pounds gross vehicle weight, 20,000 pounds on a single axle, and 34,000 pounds on a tandem axle group."
12,000 lbs = 5443.10844 kg, 74,000 lbs = 33,565.8354 kg, & 80,000 lbs = 36,287.3896 kilograms.
So Machoke definitely earns its Class 50 rating.
TL;DR - BOTH of Machamp's pre-evolutions have better lifting feats than Ride Pokemon Machamp pushing boulders. (& both also have seemingly laughable feats like "throwing a number of Geodude" (Each Geodude is about the weight of a 6 y/o girl.) or hefting a sumo on one finger when no real sumo has weighed over 265 kg.)
