I am currently reading a 1643 treatise on archery, written by a Chinese expert, and it sounds quite modern (not so surprisingly as the bows will teach us what we need to know).
I am fascinated by fact that they used quite heavy bows, but of course these were a military weapons, not just a target toys. Once they developed good form they would begin exercising to build up their ability to draw heavier drawing bows. Some of their practice bows went over 200# of draw! These were bows that were designed not to be shot, just to train with, but there were occasionally bows with such draw weights that were designed to be shot. Just thinking about that causes me to ache!
So, do you know any exercises designed to be able to increase the amount of draw weight you can handle? If so, I would like to know about them.
PS I will be writing a review of this book for Archery Focus magazine as soon as I get it done. Interestingly the author was shooting off of the point 200 years before Horace Ford popularized that practice in the western tradition. I think westerners could learn a few things by looking at Asian traditions.
