My fiancee has a bad case of kyphosis and when she performs a deadlift, she said she has terrible pain in the middle of her back, just where the curve starts (right about the bra line). I emulated her posture and felt the same pain in my mid back (not a bra line).
I have done some reading on this site, specifically the Neanderthal No More articles, and know some of what I can have her do to help fix her back. It seems to be bad enough that she may require more than just improved length/tension ratios.
In the mean time, what posterior chain exercises can I prescribe in place of deadlift that will have the greatest weight loss effect? All I have available at home are free weights and a bench press.
