What Terry said...
I am a newer trad shooter as well (a lil over 3 1/2 yrs).
But even in the training wheel realm, the basic rules of form are somewhat the same... Aim for a "T" of the torso and arms and bend at the waist as Terry said (and looking at his form videos, now he can shoot!)... Or once you shoot down from a treestand and drop that arm, you're going to shoot high everytime... even with a sight..( its a trigonometry thing, and I don't wanna go there...)
