I have to say, when I first saw this I thought, "how can starting your draw with anything less than perfect straight alignment make sense?"
Wow, do I ever feel stupid for questioning this! It is truly amazing how that draw works into back tension AND good alignment. Thank you so much.
I'm a rookie and I was having a hard time "feeling" my back tension but not with this technique- you can feel the tension in your shoulder blades continuing through the draw. And the whole string rotate into you has helped with my grip and less bow torque on the shot.
