you can practice your form with a light bow,,
some shoot without hitting an anchor,,
especially on a short draw bow,,
it you want to hit anchor and pause and then pull through the shot,,
then you have to practice like that,,
if you want to shoot with no anchor,, then practice like that,,
its up to you,,
if you are hitting what you shoot at,, that is what is important,,
there are lots of ways to shoot a bow,, and many opinions on how to do it,, but bottom line is hitting where you aim,,
you pull the string back and let it go, simple, ,but also complicated,,,
at one time when making sinew bows,, I shot heavy short draw bows,, I never hit anchor,,and it suited me for deer hunting,, now I am elk hunting with a longer draw bow, I do hit anchor and pull through the shot,, but that is how I practice,,
if you want to do that,, stand close in front of the target,, close your eyes and pull to anchor, open your eyes and shoot,,, so you get the feel of it,,
then practice hitting anchor and shooting like that only ,, till you get used to it,,
