My chiropractor said not to sew more than about a half hour then get up and do something else, then sew, etc. So I sew, then cut, then press, then whatever, then sew. It is hard to do because I was used to sewing long hours at a time. So I try and keep to what he said to do and it does help. So I keep my ironing board away from my sewing machine and keep my serger further away so I can't just sit and swing from one to the other or I would be sitting in that chair till I hurt so bad!
