find a good trad archery coach
good shooting is built from the ground up. there is an ergonomic, unique basic form that will apply to each of us. what works for me may not work for you and vice versa.
many of us have 'stumbled' upon 'good form', and that's the long, hard way. the smartest and fastest way to good form is in finding a good TRAD ARCHERY coach. check with local clubs and national orgs.
there is no substitute for learning proper fundamentals as they apply to you, not to me, and not to those other guys. trust me on this.
