I'm sure many have tried doing it. But many of them don't do deads and back squats. Like the Diaz brothers, I don't know if they deadlift and back squat. Probably not much if they did. Nick had a belt, and didn't strike me as the type to do it. There are many beltholders that you just don't see them doing these things.
Plenty of people got pissed in this thread when I said that many people in this forum have better deadlift squat numbers than the mma beltholders.
I think pretty much all top fighters are very strong. There is a difference between strength at deadlift and back squat and strength in the cage. Prime Anderson Silva would do what he wants if you get in his clench. You would say he's incredibly strong in the cage. But with deadlift and back squat, he would be unimpressive.
Holy shit. As others have already proven, most of them do squats and deadlifts. You keep saying this stupid shit that many don't, when it's not true. Just get over this stubborn desire you have to be right and learn something for once. Nearly every pro fighter has years of strength training under their belt, and almost all real S&C coaches will have you doing squat and deadlifts, or variations of because they recruit the most muscles and have simple progression schemes. Nobody is saying that you shouldn't train technique. Nobody is saying that you shouldn't do plyos and other things also. You don't see them doing those things because you don't watch them train 24/7. It's not exciting to watch so they don't put it on Youtube. You don't see 99% of their training, but this is the one thing you make that giant assumption for.
Who is mad that you said there are powerlifters on this forum with higher numbers than MMA pros? Nobody. They are mad that you're creating this illusion that they've never picked up a barbell in their life and couldn't squat their bodyweight or pick up a barbell with 45s on each side. It's blatantly false.
There is no difference in strength in a barbell movement and strength in a cage. Your body doesn't give a single fuck why it has to apply force, it just does it. Whether you are driving your back into a barbell in the bottom of a squat, or doing some other movement, it doesn't matter. You're mistaking technique for strength. Proper technique in the cage can give the illusion of strength, but it's not strength, it's proper leverage.Nobody is saying MMA fighters should have a 4x bodyweight deadlift or a 2.5x bodyweight squat. They are saying that a fighter who does deadlifts in his strength block will have a stronger posterior chain, which will allow him to produce more power than a fighter who doesn't deadlift.
And again, literally every other sport in the world that requires power uses fundamental sports science to better their athletes. They are all doing squats, deadlifts, and presses because they work. NFL players squat and deadlift. Hockey players squat and deadlift. Track and field athletes squat and deadlift. Baseball players squat and deadlift.
Literally all of them are doing these things because they work. If you want to increase power you need to increase speed and limit strength. The best way to increase limit strength is to pick up heavy things. The best way to keep track of how heavy the things you pick up are to standardize them in some sort of way, like a plate. The best way to load plates is with a barbell. Your body doesn't give a fuck how you add resistance, only that you give it resistance. The best way to load resistance for limit strength is with barbells.
And any athlete who is successful without using that training method is succeeding despite their training.
EDIT: Rico Verhoeven is the heavyweight champion of Glory kickboxing. Here he is doing barbell squats. He CLEARLY does them fairly often. I can continue to search the internet if you really need me to.
Jason Wilnis is the middleweight champion of Glory kickboxing. Here is a diary where he talks about a 480lb squat and a goal of 500lbs.
