I use the hook and pull method.

Adjust your release strap and such so that you can hook your finger deep over the trigger, between the 1st and 2nd knuckle. While aiming, push steady tension with the bow hand toward the target and pull backward, in a straight line with your release hand.

Your release hand/finger is just a solid hook. To pull backward, point your elbow backward and use your back and shoulder blade muscles to cause the pull.

This is very hard to explain, but you must keep your push and pull in the same plane. Try it while standing real close to a blank bale until the shot goes off and surprises the daylights out of you......... that's what you want.

Get a routine......... place your feet...... nock an arrow............ get your grip......... point your bow at the target and draw smoothly back and anchor. Then you hook your finger..........start aiming and pulling simultaneously. The shot should go off unexpectedly while aiming within 4 - 7 seconds. If it does not, let down and start over. Try pulling a little stronger and/or hook your finger deeper. You'll have to experiment.

The whole idea is to be totally just aiming and have the shot go off. It prevents anticipation and punching the trigger.
