"Relax the bow arm a bit and get that elbow back and locked in. Maintain the draw and then a SLIGHT push to the target and release. If you can't collapse the bow arm and push it out several times with out the anchor moving it is not fully drawn back and locked into anchor."
Thanks Wapiti. I think your little comment there probably helped me more than anything I've heard or tried in the last year or so. I know your advice was aimed at getting the string arm back and locked, which isn't my problem, but it is also great advice for the bow arm. I never considered moving my bow arm in and out while holding at full draw. It doesn't take much of a movement to really give you the feeling for what it means to "push" with the bow arm. When I was at a clinic with Fred Asbell, he commented that I don't really seem to be pushing with my bow arm, but am just sort of holding it out there. Now, I can finally feel the difference between pushing with the bow arm and just holding it out there. It had an immediate positive effect on my accuracy.
