So if you have shoulder issues and when you shoot as you go to start your draw cycle, do you hike your shoulder up towards your ear? Stand on any public archery range shooting line and you will see people doing this! Raising your shoulder prevents your back muscles from firing and prevents having any real back tension, so instead of using a major muscle group to draw your bow, you are using a minor muscle group and putting a lot more wear and tear on your shoulder!!! If you have the coin, the Solid Archery Mechanics video course from Tom Clum might be worth your time, especially if you don't have an actual shooting coach available in your area. Think they have an installment plan to pay for it, believe is $200 total, probably pay for itself in non lost or broken arrows etc over time!
