In my long slow quest for back health, I've found squatting, deadlifting, goodmornings, and lots n lots of O-lifting to be good for me. In general, though, twisting gives me lots of issues (either russian twists, which I no longer do, or a batting cage, golfing or sledge hammer strike type movements). I have 2 questions:
1) what, other than throwing, would be a natural twisting movement?
2) what kind of progressions/ assistance work would you recommend for improving the quality of this movement in a person (Turkish Get Ups?, KB Windmills? anything else?)
