BLANK BALE

Shooting at a blank bale (surface with no target), will greatly enhance your shooting form and mechanics of your shot. I mean like at least 50 arrows a day for a month or so. Do it a lot. As far as equipment, string loops help, a well-tuned arrow rest (drop away or not), good arrows (straight, same weight) and a smooth release whatever that takes (back tension, etc.). A good attitude and the ability to forget the shot you just executed. Each shot is independent of the previous. There's a lot of little things that can help, but those are the main ones I can think of right now.
