I was wondering what sort of training people do for archery. I am trying to improve my strength so I can be able to hold my bow at full draw for longer periods of time I.e. 30 seconds. I’m 64 years of age and want to be able to hold my bow at full draw to prevent arm fatigue, shakiness, and wobble. I pull 60 lbs and bow is set at lowest poundage. Not interested in a new bow. Thanks.
