What works today

• This app tracks your exercises, sets, reps and weights.
• Whoop tracks the cardio strain of the session via the band.
• Whoop's API is read-only for workouts — there's no way to push sets/reps into it. So the two live side by side rather than merging.

Your routine at the gym

1. Open the Whoop app → + → Start activity → Weightlifting (or Strength Trainer).
2. Do your workout here in Lift Coach.
3. End the Whoop activity when you finish. Done — strain recorded.

Phase 2 (optional, later)

We can add a tiny Cloudflare Worker so this app reads back each session's strain & heart-rate from Whoop and stamps it onto your log. Needs you to create a Whoop developer app (client ID/secret). Say the word and I'll build it.

Worker endpoint (leave blank for now):

Full-Body Calisthenics

Tap start and follow along. Each move opens with a 15-second setup and explanation. The warm-up and cooldown walk you through every step on their own timers; timed holds count down and beep; for everything else you get a big set-and-rep target and count your own sets. Tap Next when you're done with a move. Your screen stays awake the whole time.

⌚ Track the strain (optional)

Before you tap start, open Whoop → start a Functional / Bodyweight activity so it logs the cardio strain. End it when you finish.
