This is what I do for a job:

I don't do a lot of shoulder shooting at the moment, but I will do in the future, and I'm wondering what I can do to build up strength and stability before I have to do it "for real".
A typical TV camera weighs between 8 and 12kg. Right now it takes a good while before my shoulder and back start to burn. However it is exaggerated when I have to get in a position less comfortable than standing up straight (crouching, half crouching, leaning forward/back, shooting at high/low angles etc). I already do a lot of core work outs but I'm hoping someone can suggest specific back/core exercises that will help out with endurance and stability. I'm new to strength training and only do basic stuff now, and I don't know anatomy well enough to identify exactly which muscles are being used.
Thanks in advance for any help you can offer
