Bowling Technique

Hi everyone!

I just bought my first ball, raw hammer and I’m trying to find a good way to bowl. I’ve noticed that my release isn’t straight and kind aims toward the side rather than going forward. Additionally, I’ve been told that having your hand stay behind the ball is important but I have trouble with doing that (could be the weight but it’s 14 lbs)

Does anyone have advice on how to swing straight and not curve to the side when rolling it forward.
