Greetings! I just pick up traditional archery as a hobbie and have enjoyed every minute of it! I recently purchased an used Browning Nomad I 46# 54" and have been struggling with it. I can barely hold the bow steady at full draw for more than couple sec. The gentleman who sold me the bow says that I should keep practicing with the bow and build up the strengh. Is this a sound advice? Would I develop poor form if I keep practicing on this bow? I see myself doing mostly target shooting vs hunting. I am about 5'7", 155lb, what size and pound bow would fit me the best? Any advice would be appreciated!
