Hi all,
What is the best way to build up muscle stamina in the bow arm?

I have recently increased the poundage of my bow and it now shoots much better and I am shooting well.
Trouble is, I am finding myself tiring early in the bow arm (not the draw) and just cannot keep it steady towards the end of a shoot and arrows start dropping low and left (right handed) due to me dropping my bow arm.
My score then just plummets from nudging BM to a lowish 1st class.


I am not sure if the change in stability is related to the bow weight increase but does seem likely as I cant think of anything I have done to increase the physical mass of the bow. I know the obvious answer would be to lower the poundage of my bow again but lets assume that that isn't going to happen.

What is the best way for me to build up the long term strength needed to last a round?


Is the best method simply to shoot more and wait for my muscles to develop to be able to hold the bow steady again?
or is there some other exercise I could do? Like holding a low weight in my bow arm to build up stamina?

Anyone else had this problem?
