RE: A serious question... I promise
What I do is I use a timer and set it for about 50 seconds so by the time I pull back the timer is at arounr 45 seconds and then I hold it until the time is up and shoot the arrow. Do it about 10-15 times before I, personally start hurting. For you I would probably do it for less time to start off, if you even want to try this. Not sure if this will work or not, it seems to work for me.
