The discomfort is...discomforting.
I guess it is one of familiarity, at least I hope so.
I expect to move less weight for sure, mainly due to it being a new motion, lack of hamstrings, and a longer ROM. I hope I don't take too big of a hit. But if Glenn's post is any indication, I hope the improvements will then transfer over to heavier LBBS numbers.
I also have clients that have shoulder trouble and the LBBS kills them (and they aren't big powerlifters, just regular people), yet I want them to squat. Besides the front squat, having the HBBS would be nice. But I have to learn it first.
Looking forward to more advice/experience on this conversion.
