It hasn't caused any pain when that shoulder collapses in. Though I can tell it would do some damage if I kept pulling through the collapse. Truthfully I have no big reason for wanting to shoot the heavy stuff, I jusst find them interesting and want to learn the techniques needed to use them properly. For hunting purposes I'm more than happy to stay in the 60-70# realm. I've had a couple instances of shoulder and humurus hits that didn't penetrate enough to be lethal. I feel like if o can handle a heavier bow that flings a 700+gr arrow with good speed, then it might be able to help bust through when my aim is a little off.
I've been hitting the gym quite a bit again, with a more structured routine that focuses on shoulder and back strength. Pull up/chin ups, overhead press, Kroc and pendley rows, the three variations of bench press, and deadlift. Those are my main shoulder and back excercises each week with other stuff around that for legs and core. A few days ago I joined a jiu jitsu class, that is a lot of fun, but made me realize just how low of stamina I've got. Between those two thing, if I don't tear myself down somehow, I should be able to build the strength to get where I want to be. Then it's just practice to make my body know how to use the strength properly. I've got some of the heavy weight bow trainer bandsaws don't have any trouble with those as heavy as they are supposed to go.
Anything else that I can add in to do is appreciated. I think I've built up a fascination with the heavy bows from reading old books and too many stories of dangerouse game hunting where the heavy gear is needed.
