Claude Cowork Plugin
🏋️Personal Trainer
Build workout programs, draft general nutrition guidance, and generate client reports
The Personal Trainer plugin helps you with workout programming, nutrition guidance, client reporting, and fitness marketing. Every command works standalone — describe your client and get professional output ready for delivery.
Use /workout-program to generate periodized training programs with exercise selection, sets/reps, rest periods, progressions, and modifications tailored to each client. Use /nutrition-plan to draft general, non-prescriptive nutrition guidance tied to a client's training goal, with a registered-dietitian referral note when a client needs specific targets, has a medical condition, or asks about supplements. Use /progress-report to draft client progress summaries with metrics, trend analysis, and program adjustments. Use /fitness-content to generate social media posts, email newsletters, and educational content for your fitness brand.
The plugin's skills activate automatically when relevant: exercise science expertise for programming, biomechanics, and injury prevention, plus fitness business skills for client retention and marketing.
Save hours every week with the Personal Trainer AI Operating System
A command center plus five connected jobs for programs, client check-ins, intake, and progress reports — drafted into your Gmail, Calendar, and Drive for your approval, with living trackers. Ambient scope-of-practice + client-privacy guards on every draft. Every prompt included — 75 skills in all.
Installs as a Claude Cowork plugin — and every prompt is included as an HTML page you can use in ChatGPT, Gemini, or any AI. How to install → Prices are in USD; Gumroad applies fair local pricing at checkout in eligible countries.
What the full Operating System adds
The free plugin builds the program. The Operating System runs your client business around it.
- Friday check-ins for your whole roster in one pass. It drafts messages only for the clients who need one and flags anyone at risk of dropping off.
- New client onboarding starts with a review of their health screen, then the welcome packet, first program block and first-session plan, in one sitting.
- Inquiries into booked consults with a consult plan, an honest offer email and a no-pressure follow-up for people who went quiet.
- Renewal talks, win-backs and price increases written in your voice, ready for you to review.
- HSA/FSA paperwork on your side: an itemized receipt and a letter-of-medical-necessity request your client takes to their doctor. It never promises a claim will be approved.
It remembers your prices, policies and voice. Drafts land in your Gmail, Calendar and Drive, and nothing sends without your click. It screens and refers, and never diagnoses, treats or prescribes.
