Two services in my business


I am a weight coach, and I run a school for women. I have two different offers:

1. One on one helping women be free from food and weight issues.
2. A membership for women to improve their physical and emotional health.

There are two different niches, but in my Instagram, I speak about self development and weight loss, and I find it’s a little bit confusing and not very specific.

Since I learned that the more narrow the niche the better, should I create two different Instagram accounts? One just speaking about weight loss and food and the other for the school for women?
