BobCo19-65,

Good point! If doing this drill hurts your shoulder, something is not right. Either technique or, more likely, too high DW.

If you feel any discomfort in your shoulder, this drill should be practiced with the bow's DW turned down so that it doesn't hurt.

Like the old joke: Patient - "DOCTOR, DOCTOR It hurts when I do this!!!". Doctor -"Well quit doing that!"[&:]

Seriously though, any time archery hurts, something is wrong and it should be corrected before you continue shooting. I've been through an injury that didn't let me shoot for a long time and it's no fun.

Thanks,
Allen
