Whatever kind of bow you have, a pretty good place to grip it is to place the handle of the bow between your lifeline and the base of your thumb. Grip the bow as high as you can on the handle without interfering with the arrow. That should give you a consistent grip. Avoid torquing by keeping a loose grip on the handle with your thumb and fingers, so that all the force of the bow is straight back against the pad directly below your thumb. Avoid the high-low misses, and the left-right misses by using a consistent anchor and learning to come to full draw and release with back tension such that you’re either pushing directly towards or pulling directly away from the target when you release the arrow without any sideways tweeks. That’s about all there is to it, really.
