Thanks, that answers my question. I'm glad you brought up the diff between BB and PL training -- I'll have to do more reading on that subject and I'm sure elements of it are controversial or touchy. But what you've explained makes sense -- it just varies a LOT from what I'm used to reading about strength training. My guess is that stuff I'm used to reading is informed most by the BB approach.
BTW -- I used to do something like box squats all the time -- they were called "hover squats" though, because you hovered over the box for a few counts before standing or sitting again. MUCH lighter weight than what you're using, though!
I enjoy reading your messages. I'm sure other people here know the answers to the following questions, but I don't. Do you work outside of the home? I've seen some of your progression pics and know that you were an athlete as a teen, but how long have you been strength training?
