Turning my results into a certain niche

I want to attract more women like me wanting to lose their muffin top for good…who are in-tuned to their body and want to heal inflammation, sluggishness, feeling blah with nourishment and exercise. Read personal development to work on personal insecurities and learn to be a leader…who want to help other women do the same and earn a living.
I want to know how I can speak to ONE niche. I know Brooke says just pick ONE but I want to know how to give VALUE to the ONE after I pick one.
