Dominant lead arm

I was just watching the “Hogan Grip” video and (I think) I heard you say that you’re left handed but swing right. I have something like that, I’m right handed but I swing left. That leaves me with a weaker trail arm. Since the best power comes from the trail arm, is there anything you had to do or something you recommend to compensate for this? I think it may be a source of at least a few of my swing issues.
