An all-in-one platform for personal trainers and online coaches. Manage your clients, build workouts from a library of 800+ illustrated exercises, assign programs, schedule sessions, and track payments — all in one place. Built with Preact + Tailwind CSS + Hono + D1. Deploys to Cloudflare Workers via Clawnify.
Think of it as an open-source, self-hostable alternative to Trainerize, TrueCoach, or My PT Hub — the coaching admin stack you actually own and can customize.
- Clients — a lightweight CRM for trainees: goal, status, contact, session history, and outstanding balance at a glance.
- Exercise library — 800+ exercises seeded in, each with a demonstration image, searchable and filterable by body part, target muscle, and equipment, plus step-by-step instructions.
- Workout builder — assemble reusable workouts from the library with per-exercise sets, reps (
8-12,AMRAP,30s…), rest, and notes. Reorder freely. - Share with clients — generate a public, mobile-friendly link for any workout (no login) that your client opens on their phone with images and instructions, or saves as a PDF. Revoke it any time.
- Schedule — one calendar for in-person 1-on-1s, remotely-assigned programs, consultations, and assessments. Mark completed / no-show / cancelled.
- Payments — a simple ledger for session packs and monthly coaching, with collected vs. outstanding totals.
- Dashboard — today's schedule plus at-a-glance client, workout, revenue, and outstanding stats.
Every screen is also a clean JSON API, so the Clawnify agent can run the admin for you — "build a push day and assign it to Casey for Monday", "who owes me money?" See agent.md.
The library is seeded at build time from the free-exercise-db dataset — public domain (Unlicense), 873 exercises, each with a demonstration image and step-by-step instructions. Data ships in the D1 seed (src/server/schema.sql); images are served from jsDelivr, pinned to an immutable commit SHA (src/client/lib/exercise-image.ts), so nothing to host and no third-party API to depend on.
git clone https://github.com/clawnify/OpenPersonalTraining.git
cd open-personal-training
pnpm install
pnpm devOpen http://localhost:5173. The D1 schema — tables plus the full exercise library and example clients/workouts — is applied automatically on startup.
