I've noticed looking at many shooter's forms that they often have their stomach sticking out and back arched. I don't do this, and was curious if this is a sign of proper back tension posture? Is this the way our bodies should look at full draw if we are truly utilizing our back muscles? I played around with my form today when shooting, and when I tried arching my back and sticking my stomach out, my bow arm became quite unstable, although I did feel my back muscles at work much more than my normal form. I will get a picture of where I'm at form wise and post it in a bit to see what you guys think. In the meantime, is this normal posture, or am I missing something?
Ok, here are a few pictures I just snapped of me from the back and from the side. You can tell I'm not arching my back, nor am I sticking my stomach out. Am I doing something wrong?
