Everyone says you can hurt your back with a heavy draw weight. I've heard of people having surgery and everything from it, even young guys. How exactly can this happen? I mean, it could be because im only 23, but im brand spankin' new to archery. Soon as I got my bow I pulled on it, it was about about 60, it was pretty tough to pull, first time i'd ever pulled a bow. But I wanted to pull 70, so I had the guy put it at 70. Well, ordered all my accessories off the internet, so I had some time to wait. For about 3 weeks every day I pulled my bow back Not because I was practicing really, but more because I was so fascinated with the bow that I always had to be touching it. Rofl, I ate dinner with this thing at my side, it stayed cuddled in my lap while I watched tv, hell I could barley leave it alone while I slept. Well i pulled it back a lot, ALWAYS promising that I would NOT dry fire thsi thing, no matter what. And there are been a couple situations where I have let it go to fast or unexpectidly and it has pulled my arm forward hard. None of this has ever hurt my back in the slightest. And now the 70lb pull is super easy for me to pull. I think I could even pull 80, although im not going to because I want to shoot to much to have to pull that much weight everytime I take a shot. So, how can you hurt your back, what part of the process hurts your back? Just repededly pulling back all this weight, or what?
