Thanks for posting this because really, I do zerchers quite often, with up to and over 200lbs on most occasions, and at first I was in your shoes thinking about the "bruising" but I just manned-the-fuck-up and started doing them. Really, they're not that bad. I typically do the "dead-stop" type where the bar starts on the floor.
Tomorrow is squat day, I'll do some, film it, and put it up on here.
Great exercise though. Totally makes you feel like a bearnocerous.
