All the pulleys do on a modern compound bow is make it so that you don't have to start training at the age of 12 to build up the strength to pull a decent weight. Welsh longbowmen used to train from being practically a child through adulthood to be able to pull their 180lb longbows and retain accuracy at 300+ metres. Nowadays a man doesn't have to train nearly half as much to draw a 180lb bow because the pulleys and strings help draw the weight for him.
