I got the Inzer Leviathan over the holidays and I can now see how some people are squatting 1201 these days. I used it on my max effort day, and I couldn't sit with 475 on my back, which is usually my second triple. I usually work up to 550 triples and go upto 660 on singles. I statred out heavier than usual, anticipating some added squatting difficulty. I ended up being able to sit at about and go parallel with 600 or so! My last single was at 875, but only out of fatigue did I stop there. I could be looking at a 1000 pound competition squat considering I have a crazy quarter squat. What feds permit the Leviathan? I recommend it to everyone!
