A release with no trigger creep will improve your shooting form. Simply curl your finger around the trigger, apply a small amount of pre-shot tension on it, then bring all your attention to where you want to hit until the shot breaks. You won’t detect any trigger movement, and the arrow will fire cleanly and crisp-like.
However, to do all this, you must get the release adjusted correctly and follow a few crucial steps.
Trigger position: If your finger barely reaches the trigger at full-draw, then the release strap or rod is too long. Shorten it until the trigger rests below the first crease of your finger while at full-draw. This will decrease the sensitivity of feeling the trigger and create more of a hook-like pattern, so you can tug on the trigger to fire the shot by pulling with your arm and back muscles altogether.
How to shoot: Back tension is the key to shooting a release properly. Yes, squeezing the trigger slowly with your finger’s pressure alone will do the trick nicely. But, eventually, this single finger will want to punch, rather than squeeze, and that’s when trouble and anticipating the shot occurs.
Overall, it’s better to rely on a stronger, more reliable source to do the firing for you—this happens to be the muscles in your back. To use them, simply rotate the right shoulder blade (for a right-handed shooter) in toward the other, and you’ll feel the pressure begin to tighten along your spine. Simply squeeze together here, or move your entire arm-unit rearward if that seems easier for you, while you aim, and the shot will break cleanly.
At first this procedure will seem awkward, but keep practicing the motion on a close-range bale until you form muscle memory and sense the power and control behind this method. In time, your shots will take you by surprise, rather than timing them like you might’ve been doing before.
When using back tension, it’s important to get a good hook on the trigger with your finger, but then to let everything else in your hand/arm unit (and body for that matter) to remain relaxed, until the back tension does its thing and sends the arrow out of the bow.
Keep practicing the technique and adjusting the weight/strength of the trigger until the shot breaks in 4-5 seconds. Everyone’s pulling strength varies, so you’ll have to play with the trigger tension adjustment. This will create a nice delayed execution, which will keep your mind focused on the shot and not anticipating when the arrow will go. Overall, this is the best way to shoot.
