What It Does

Two pre-built workouts for the Beastmaker 2000:

Max Hang — 6 sets of one-arm hangs on the 4-finger jug. 10s per arm, 15s switch, 3min rest.

Cooldown — 3 sets of 30s two-handed hangs on any hold. 1min rest.

Features:

• SVG hangboard diagram with active hold highlighted
• Large countdown timer readable from 5+ feet away
• Audio beeps for go, stop, countdown, and rest warnings
• Dark theme for gym visibility
• Screen stays awake during workouts (Wake Lock API)
• 5-second "get ready" countdown before first hang

Tech

Static HTML/CSS/JS. No framework, no build step, no backend. Uses Web Audio API for beeps and inline SVG for the hangboard diagram.

index.html   — structure and inline SVG
style.css    — dark theme, mobile-first layout
app.js       — timer state machine, audio, workout definitions

Run Locally

Open index.html in a browser. That's it.

Or serve it:

python3 -m http.server 8000

Modify Workouts

Workout definitions live at the top of app.js in the WORKOUTS object. Each workout has a name, target hold, number of sets, and an array of phases with labels, types, and durations in seconds.
