i do 4 differant stretches before i decide to shoot my heavy bows
1 "wake up stretch"- this is just where you stand on you toes and reach for the sky stretching your entire body
2- shoulder- i act like im going to draw a bow and i work on pulling my shoulders together and then when im at "fulldraw" i drop my elbow and squeeze together for a 5 count
3- more shoulder stretches- reach across grab elbow and pull across chest trying to touch other elbow
4 wrist/fingers- i roll my wrist and then i take my fingers and push them apart, same stretch i use for guitar warmup haha
