I've been a boom operator for only a couple of years, and I aim to continue doing this for some time. However, I am concerned about potential future back problems. I obviously stretch before shoots, excercise proper posture (no leaning) and have an extensive collection of muscle-soothing ointments. I was wondering if anyone could suggest techniques and equipment for taking the strain of operating off your mucles, as well as any excercises that may help to improve your necessary "booming" muscles.
Cheers.
