There's also substantial evidence showing what some sort of targeted core workout (like planking and side leaning rests) can do for helo guys (both pilots and aircrew).
Completely agree. I've got quite a few years in helicopter cockpits and no back problems which I attribute to weightlifting, in particular deadlifts and squats. If you are going rotors, find an exercise program you can stick with to help prevent back pain. (Also don't forget double hearing protection.)
