Hmm, ya, I see what you mean, especially on that last video. I think the hip drive can be achieved without creating extra focal points in the spine, which was the main point I got out of the 1 Joint Rule, but then that last video you posted, ya, I dunno.
Ya, he was talking about deadlift, SLDL, then overhead squat, as opposed to the low bar squat Rip is doing. I'd be interested in seeing how he applies that rule to the low bar.
Cool, thanks! Was actually just thinking about my shoulder flexibility last night. I think i'm probably already very flexible there as well and don't need shoulder dislocations. It was just something I'd always done, and my friends who olympic lift do them as part of warm up so I just continued to. What RC exercises do you do? Cables and rowing machine?
