Yes, Dave Tate was a multi ply lifter… one of the best to come out of Westside behind maybe Chuck Vogelpohl and Matt Dimel… he hit a 700+ lbs High Box squat 7 days post Total Hip Replacement (anterior approach), the video is on YouTube. multi ply is a whole different monster. I competed single ply for a while, then switched to multi ply, I hated it so much I went back to raw… 6 hour squat sessions, and fighting 3 grizzly bears to get a fucking squat suit on was not fun… I would do single ply again, but I’m not sure my hip would like the position a squatter would put it in, plus I’m not sure I would get much carry over from a deadlifter…
I’ve met several EFS and Big Iron lifters, all disciples of Louie, it’s very humbling being in the company of people like that, they’re all on a completely different level of crazy, but they all had very good information to hand out on different training methods and how to bring up weak points in different lifts.
