| Having come off major back and arthritis issues several years ago, I say it's a combination of things: weight of the bow, size of the bass (especially shoulder bouts), whether you play sitting or standing, height of stool etc;
I found that (among other things) working with a lighter bow (I have three between 126 & 134 gr), low tension strings (such as Corellis), smaller basses, seated playing (and occasional use of a bent endpin) I can enjoy playing for several hours at a time.
Is it as loud and vigorous as I would like? Not always - and sometimes, with the German bow, I let the wrist and fingers carry the load (see Streicher method).
Not ideal and it won't win me any big time auditions (not that I was planning any) but does allow me to keep playing and having fun
