Uneven abs/stronger side

Hello! I need a little help...

I've been working out every day for some months and I've noticed that my lower abs in my right side (dominant side) are getting stronger and bigger than my lower abs in my left side, basically is my stronger side taking over.

So I need abdominal exercises that focus my lower abs and I can make my left side work harder than my right side, to even things out.

I tried reverse crunches focusing on my left side, but I ended up having stronger obliques in my left side without fixing the problem lol. That's why I need someone who knows what he's doing!

Thank you and God bless you!
