I have pretty good form and shoot well. Once I my draw arm is locked in I can pretty much hold an arrow at full draw with no creap as long as I want to. (a minute or close)
I notice that my bow arm seems to fatigue rather quickly and I'm thinking its a form issue.
Granted its not a fair comparison as I actually have my back locked it and not really using the muscles of my bow arm. I'm just thinking that a steady bow arm should be pretty steady as it should be held in place by alignment.
Any thoughts? I'm a terrific shooter but could always be better.
Which technique are you using for your bow arm, locked out straight, or slight natural bend? If you are locking your joint out straight, I could see there being a marked increase in fatique as this actually adds stress to the muscles and joints. Same as standing at attention with your legs locked straight vs having a slight natural bend. Same thing applies, locking out adds tension whereas slight natural flex does not.
Second would be the drawing technique. I could see where using a push/pull technique could fatigue your bow arm quicker than a different technique.
Just a couple of thoughts with the limited details you posted.

I have it slightly bent. I think your right Daddy Bear. Maybe just the push pull
I notice that if I focus on shoulder geometry and alignment (Terry's clock) it puts less muscle effort into keeping my bow arm solid. This becomes more obvious after I have shot for awhile and the muscles have tired. I don't bend my bow arm much because I have a short draw as it is.
