Hey y'all,
As mentioned in my one previous thread, I'm a fairly new shooter and a brand new forum member, and as such am the least qualified person here to be giving advice. BUT... as a result of reading through some of the threads here in the FORM forum about back tension, I've gotta share my experience because it might help other new shooters like myself. I apologize for the length.
My son and I recently bought identical Bear Grizzly 50# recurves (probably too much, I now know) and took up shooting, and have quite frankly been tickled at how quickly we became tolerably good, regularly hitting a 20 oz. soft drink bottle suspended in front of our backstop at a measured 27 yards. The only problem with me is that (1) my draw length is 29.5" by any measure, which means I have to overdraw my 28" draw bow slightly and it stacks, and (2) I'm 58, and usually after a long shooting session my shoulder feels like I have a knife wedged down between it for a few days afterward.
But after reading here on the subject of back tension I started examining my form in a mirror and I realized that I had developed what I believe to be a bad habit of, as I sort of rocked back and forth before drawing, my rear (string) shoulder was in a forward position and therefore when I drew it was all being done with my upper arm and shoulder. That was a pretty big strain on my muscles, made it difficult to fully reach my anchor point, and my elbow stuck out like a chicken wing. But then, as I started trying to implement some of what I had read, I realized that by keeping my rear shoulder back and not letting it slump forward before drawing, all the strain was off my arm and shoulder, and not only could I draw without pain (my shoulder was already hurting and I had planned about a week layoff to let it heal) but that I could hold it at full anchor as long as I felt I needed to. I then took my bow outside to put it to the test, and the results were astounding! No pain, could hold at full anchor with no difficulty, and hit where I wanted to. Man, I wish I had read some of this stuff earlier.
So my point is, for me, being able to use the back tensioning method effectively was as simple as starting my draw with my rear shoulder well back instead of slumped forward. I don't know that it would be that simple for everyone but it was for me. Thanks!
