My hunting partner employs bow shoulder scapula expansion.
Once he determines that he is winning the battle, he releases.
I have in no way been able to master it. When I am able to employ it effectively, the results are most excellent. My own discipline, to relax, is lacking and Arnie's method is much more personally conducive to faciltate a consistent relaxed shot execution.
He teaches this method in his archery school once certain controls of the shot execution are mastered.
Not all methods are best for every one. Apparently, his is a personal best fit with capturing 5 Traditional World Titles and 16 National titles, all within the last three years.
Trad Gang is most fortunate to have Arnie and McDave as shooting advisors...Thank you both!
