Welcome! You picked a heck of a bow to start with. Dwyers are one of my bucket list bows. Wise choice on the poundage also. I've been at this for over 40 yrs, trust me, shooting a stickbow takes a specific set of muscles. I can't stress enough the importance of going at this like any other sport - excercise and build the strength needed to perform without injury. This and other forums are full of threads about shoulder injuries, joint problems, and other shooting related injuries. This doesn't need to happen. Shooting a bow is a physical activity. You can't expect to do it well without strength and conditioning. I am 52, use free-weights, push-ups, pull-ups, and can comfortably shoot more draw weight now than I could in my 20's. Take it slow, be smart, and work into it and you will enjoy shooting for many years to come.
