I had to ask this. I was working a yew limb it was 1 3/4 at one end 1 1/4 at the other about 5' 6" only pulling 30# 28. I usually try to exercise / draw a bow after strung and before I shoot it. Last night I strung this bow, knocked and arrow and drew it back. It sounded like a rifle going off, the bottom limb blew in two places. My question is, is not exercising the bow out at least one of my causes of this explosion? Thanks in advance. Ed.
