before fiddling with settings on your own,
take it to a range/shop and check what the poundage is set at,
and what draw length the bow is , and what you should be pulling
and see about having it adjusted to min setting on the bow.
then can work on form for drawing.
aside from poundage, if the draw length is too long, will have a hard time drawing it back, as your arm/shoulder has no leverage where you need it.
when drawing, its not just a straight pull,
but also pulling with your shoulders by twisting your shoulder back,
much more strength in shoulder than forearms,
if you still find yourself reaching for the sky when drawing, poundage is still too much,
there is a use for higher poundage bows,
but not for everyone,
and can get better accuracy and longer hold times with lower poundage bows.
my bow is a 60-70# bow set at 62,
next bow i get will probably be a 50-60# bow
