Hi Jon, it may not be as hard as you think, a good part of it is mental and if you have enough desire you can make it happen. Paul Brunner is almost a midget(sorry Paul) and he is shooting 85#'s everyday and he ain't a spring chicken either. I'm no spring chicken either, but like Ryan I have been shooting bows almost my entire life. 85#'s wasn't all that bad really, I could draw it the first time I picked up a bow that heavy, shooting it repeatly did take a bit more effort. The best exercise for shooting a bow, is drawing a bow or at least the same motion as Ryan mentioned with the rubber band device. I leave a bow strung in my house all the time and pull it and hold SLOWLY a few times whenever I think of it, first with one hand then the other. I only shoot right handed, but you will develop faster and with less problems if you work out both sides. Also, remember that ANY exercise benefits your entire body, even walking helps benefit the arms and back muscles, so cross training is a very good idea. Also its a benefit when buffalo hunting to be good at sprinting and climbing smooth trees with no branches, very quickly!8^) Rick
