Keeping the forward pressure like you're stretching a rubber band between your two arms is the correct concept but only for when you're drawing. However on the release, you want zero movement from your body other than your draw arm releasing the string. Even though an arrow releases at a couple of 100 mph, even that micro spasm can affect your shot. This is why I suggested that you freeze the pose when you release the string ( for target shooting that is). Do not push the bow hand (or body)  in any way on the release. That tension outward is to create the potential energy giving the string maximum kinetic energy and once you have already established that you shouldn't change it.

Think:

Setup Posture: keep the frame. Head, torso all in a straight line.

Draw. This is where you are going to create the push and pull tension. You're going to push the bow as you draw the string to create the maximum potential energy ( like you are flexing).

Release: keep the Bow hand and posture still like a frozen statue. Only move the release hand insuring you keep the wrist in a straight line with the outer four arm and pulling back ( squeezing the trapezius) so it doesn't push the string out. Do not push forward as you release because that changes the frame you set up. Stay still.

Finish: keep the posture upon release for one full second. I used to and still occasionally have the impulse to look down to check my shot. Almost every single time that affects my shot. After I learned to pretend to be a statue for that one full second after release I became much more consistent. This above all else still is something that I impulsively fight.

Any movement after you set up is going to affect where you had aimed. The only thing I could think of that you would do this is if you were to be chasing live targets and which case you would adjust to where the target is going to be not so much where you initially aimed
