My1RM

Static Cloudflare Pages MVP for a squat, bench, and deadlift one-rep max calculator.

Scope

• Estimate 1RM from working sets using an average of Epley, Brzycki, and Lombardi.
• Show squat, bench, deadlift, SBD total, and bodyweight ratios.
• Show a transparent demo percentile model by sex and age band.
• Use a Cloudflare Pages Function at /api/location for coarse country/city labels.
• Include privacy, terms, methodology, robots, sitemap, and ads.txt placeholders.

Non-goals

• No account system — ranking records are anonymous (no name, email, or user id).
• No raw IP stored — leaderboards use coarse city/country from the connection only, no street-level tracking.
• No medical, coaching, or competition judging claim.
• No build step or npm dependency in the front-end MVP (D1 runs server-side in Pages Functions).

Local verification

node --check app.js
node --check functions/api/location.js
node tests/calculator.test.js

Open index.html directly in a browser for the static UI. The location endpoint only returns Cloudflare metadata after deployment through Cloudflare Pages.
