>>76394903315 does not take 3 years of training, it's elite-level that only competing powerlifters, strongmen or 100+ bw male weightlifters can achieve (almost always with PEDs).
I don't think even Clarence hit 315, he only maxed 310 paused. Toshiki has only achieved 321 and he's an (ex-) olympic weightlifter.
315 is just not in-reach for the average gym-goer.
