I checked their profiles, they do squat a lot, but it's mostly high volume with moderate weights, like 80kg/176lbs and typically in smith machines. But they also do all kinds of shit like leg presses, hack squats, lunges (also in smith), etc. Basically anything that can grow their legs, especially quads.
Personally, I can't do leg presses in most machines because I have big glutes and pushing the platform flattens my lower back really uncomfortably. I actually hurt my back that way in the past, fortunately, it resolved its own after a couple of day, but that's hell while it lasted, sneezing, walking, even farting would result in a sharp pain, lmao. That's why I prefer hack squats and high bar squats, don't use belts tho because belts teach you to push against them which is no bueno, imho.
