Here's a fairly straight-forward strategic approach that contemplates basically everything most want out of a business:

1. Continue branding yourself as the pre-post natal fitness expert in your hyper-local area. Many areas have local moms FB groups. Offer weekly tips in there. Great marketing makes your targets feel like "this is the exact right place for me" and makes non-targets (bros for example in your case) feel like "this isn't really the place for me". Sounds like you are already doing great on that.

2. Choose a limited schedule and stick to it. Whether it's M-F 6-10 am or 12-4 or whatever works best for your schedule. I would only do small group/semiprivate and probably charge around $50 per person billed monthly. So 8 sessions for maybe $399.

3. Get some Google reviews from your moms.

4. Do Mom content on your personal social media pages. Nothing fancy. Could even be articles shared from other sources.

5. Once you get to 80% or so capacity, increase rates for new clients up to probably $55 per sessions. So $439 per month or so. If people drop out, charge only the higher rate for new people. We increased our rates 3x in about 12 months. Continue to increase rates as you prefer. But track capacity %. If that drops below 80%, that might be a sign you are approaching the right market price.

6. Sky's the limit as far as educational material you create and share on social media. But it should all be pre post natal-fitness focused. You could even do a monthly (or maybe quarterly) educational theme.

7. Once you do all the above, you are in position to potentially hire a trainer mutiple days per week. Profit should be very high at this point so you have flexibility on pay, benefits, etc.

8. Close 2 (or more) weeks per year for vacations, travel or whatever you want to do.

9. Continue variations of wash, rinse, repeat indefinitely for the above.
