The fact that Brady Ellison is the only US archers during his career that he couldn't beat kinda say so much about both him with his technique and Brady with his overall skill
I walk dogs for a living (it's awesome) but I think because I've been doing it for many years and only shooting for 1 I have a bit of a death grip on the string and find it hard to relax my fingers because in my job I can't relax the dog leads or they pull and I could drop them etc. Sometimes I feel concentrating on where the arrow flies helps me not think about the release so it's cleaner not forced but still trying to get there! 😂
Then just don't think. A simple exercise is to fill a bag with some weight and let it hang from your side from your fingers in the same position as the string would be in at full draw then close your eyes relax and practice just letting the bag drop without thinking about activating it.
