Marketing Lessons Fitness Pros Actually Need.
Practical Education in Marketing, Strategy, and AI for the Fitness Industry
DuoCore courses are designed for coaches, trainers, studio owners, and wellness brands that want clearer strategy, better execution, and education they can apply immediately. No generic theory. No recycled business advice. Just practical systems built for this industry.
Your Fitness
Marketing System
The Claude AI Course Built Specifically for Gym Owners and Personal Trainers.
Your Fitness Marketing System is DuoCore’s flagship course led by Marc Coronel, IDEA Personal Trainer of the Year 2024. It is built for gym owners, personal trainers, and fitness business owners who are tired of inconsistent marketing and ready to build a system that actually runs.
This is not a collection of AI prompts. Over 4 hours of video training, Marc walks you through building a complete Fitness Marketing Brain inside Claude — a system that knows your gym, your members, your voice, and your market. Once it’s built, every piece of content, every campaign, every email starts from a foundation that knows your business cold.

13 Skills. Four Systems.
One Complete Marketing Engine.
Every skill in this course produces something you keep and use. Not notes. Not theory. An actual working system built around your gym, your members, and your market. Here is exactly what you walk away with.
Your Fitness Marketing Brain
The foundation everything else runs on. In one session, you build five context files inside Claude that capture your business, your members, your brand voice, your offers, and your competitive market. Every skill in this course uses these files automatically. Build it once. It runs forever.
Without It, Claude Is Generic
A prompt run in a blank chat could belong to any gym in any city. The Brain changes that. Once it exists, Claude knows your specific business cold — and every session you run from that point forward produces output that sounds like you, not like a template.
Content Multiplier
One source — a member story, a seasonal moment, a new offer — turned into a full week of platform-specific posts. All calibrated to your brand voice and the 40/30/20/10 content formula. A week of content in one session.
Challenge & Campaign Brief Generator
A complete marketing brief for any promo — a 6-week challenge, a New Year campaign, a membership drive. Messaging hierarchy, asset list, channel plan, timeline, and ROI math. The document a marketing agency would charge thousands to produce.
Referral System Builder
A structured word-of-mouth program built around your specific members, your offer, and your gym culture. Not a generic “refer a friend” discount — a referral system your members actually want to participate in.
Local SEO Content Engine
Google Business posts, review response templates, and local landing page copy — all optimized for the searches happening in your area right now. Built to help your gym show up when someone nearby is looking for exactly what you offer.
Campaign Calendar Builder
A full promotional calendar built around your specific offer rhythm, seasonal moments, and member lifecycle. Stop improvising month to month. Run a calendar that plans itself.
Lifecycle Email Optimizer
Welcome sequences, trial nurture, and retention campaigns written in your brand voice. Emails that build trust, move prospects to action, and keep current members engaged — without writing from scratch every time.
Retention Campaign Builder
Targeted campaigns for the members most at risk of leaving. Re-engagement sequences, milestone moments, and loyalty messaging — built around the specific language your members use and the moments that actually move them.
Fitness Ad Creative Lab
Score your existing ads before spending another dollar. Analyze what your competitors are running and why. Generate five new campaign concepts built around your specific customer’s language and motivations — not guesses.
Landing Page Builder
Full landing page copy for any offer or campaign, built around your real customer language and your actual transformation promise. Connects directly to the Campaign Brief so the message stays consistent from ad to page to conversion.
Fitness Copy Auditor
Score any piece of marketing copy across four dimensions. Know what to fix before it goes out. Run it quarterly to keep your messaging sharp and current as your business evolves.
Marketing Report Builder
A structured marketing performance report you can run monthly. Tracks what’s working, what isn’t, and where to focus next. Turns your results into a clear picture instead of a spreadsheet you never open.
Local Intel Gym Scanner
Competitive intelligence on your local market. What your competitors are doing, where they’re leaving gaps, and how to position your gym to win the customers they’re not reaching.
