The most I've recently pulled was 435, at 175 bodyweight. I don't use a belt, just chalk on the hands. The only deadlift training I've done is deadlifts themselves, although I think training heavy squats helps deadlift quite a bit. I never go over 3 reps on any set of deadlifting. I only deadlift once a week, and I do it after my squat workout, a la Thibs' HP mass program. However, I do less Deadlift volume than he prescribes, and I incorporate heavy doubles and singles. And I only deadlift once a week. I was maxing at about 315 on deadlift about 4 months ago, so the way I'm currently training seems to be working well.
Question for you guys, how much benefit do you think you get out of a belt? I've never used one for any lift. I know I could get a bit more weight out of my squat with one if I ever strap one on, but how about deadlift? Do you use it for safety/stability, or do you think you're actually lifting more weight because of it?
Not trying to hijack the thread, just curious.
