I' m 5' 7" with regular arm length. With my old bow, I drew 30" . With my new bow I' m now drawing 29" ....alot of people say I should be drawing 28"
You must have long arms if the above is correct I am 5' 8" and my draw lenght is 28" .
I would suggest you go to a good Pro Shop and get measured for correct draw lenght.
99 % of the time this is caused by having a bow with too long a draw length.
david is 100% correct
