About Buff Book
Buff Book is a repository for a hypertrophy wiki and custom training plan platform. The wiki covers the biology of muscle growth, exercise selection, periodization, and nutrition. Users can submit requests for personalized training plans through an application flow, and an admin dashboard is used to manage requests and upload completed plans to cloud storage.
The site is built on Cloudflare services, including the D1 database and R2 object storage, with Better Auth handling user accounts. The admin dashboard is designed to sit behind Cloudflare Access in production. Running the project locally requires Node.js v18 or later, npm, and the Wrangler CLI. The README describes the project as open source and licensed under CC BY-NC-SA 4.0, which limits use to noncommercial purposes.
