Definitely understand the technique aspect of it, I don't mean to undermine it. I suppose I'm just thinking that a bodyweight squat isn't "too" challenging to hit for 5, while a 2/3 press would be "fairly" demanding.
5 rep body weight squat would require like a 1.2-1.3 bodyweight 1RM, while a 5 rep 2/3 MP probably needs a .9 1RM. I would hazard a guess there are a lot more 1.3 BW squatters than .9 MP's out there. It would actually be interesting to hear more people's thoughts on this part than my initial question.
I love the OH press too, though admittedly do much more with 1 arm than 2. I can 1/3 BW press with each arm with the KB, so I would think I can hit the 2/3 BW with both arms, with the caveat of course of improving my BB OH press technique.
