 Why openGym

Most workout apps keep your data on their servers, push you towards a subscription, or vanish
when the company does. openGym runs on your own box, keeps your data in a folder you control, and
is yours to fork. It still behaves like a modern app: installable on the home screen, passkey
sign-in, works offline, syncs between your phone and your laptop.

No account on someone else's server, no subscription, no ads, no telemetry. One
docker compose up and it's running.

The in-browser demo is the real app with example data,
if you want to try it before installing anything.

 Features

Planning

- A routine per weekday over a library of over 5,600 exercises with animated demos, searchable and
  browsable by muscle on a body map. Filter by the equipment you own.
- Four starter plans (Push/Pull/Legs, Upper/Lower, Full Body, 5×5) that load as ordinary,
  editable routines.
- Every session on the Plan page and today's on Home carries a tiny body map with the muscles it
  works lit up, so you know Leg Day is legs before you open it.
- Move a session to another day without touching the weekly plan. The week starts on Monday or
  Sunday, your choice.
- Or skip the weekdays altogether: a rotation (A, B, C, A, ...) where the next session is
  simply the next one you haven't done, however the week went.
- Supersets, warm-up sets, drop sets and rest-pause, timed exercises (planks, hangs, carries),
  cardio by time and speed, rest time per exercise, planned deloads.
- Your own exercises, with your own photo, GIF or short video. Location data is stripped on the
  device before upload.

Training

- Guided sessions: today's workout starts itself, weights are pre-filled from last time, a rest
  timer runs between sets, PRs are detected as you go. On a rest day it tells you when the next
  session is.
- A quiet workout screen: one menu per exercise, the set number as the set's own menu, card or
  list view. Switches in Settings bring the old button rows back if you liked them.
- Optional effort column as RIR or RPE, colour-coded, with a plain-language line per level.
- Plate math for barbell, EZ bar, trap bar and Smith machine, worked out from the plates you own.
  Train in more than one place? Each gym keeps its own plates, dumbbells, bars and machine stacks,
  and the phone can switch to the gym you just walked into.
- Bodyweight exercises know they carry no load: log reps, add a dip belt if you use one.
- Per-side reps for lunges and single-arm work, the screen stays awake while you train, and a
  rest-timer alert can flash the screen for loud gyms.
- Swipe a set left to delete it (with Undo) or right to copy it. Pyramid sets with their own reps
  and rest per set, and a scroll wheel for any rest time up to 15 minutes, or no timer at all.
- Machine taken? A planned backup exercise swaps in with one tap and keeps the slot's sets and reps.
  Machines can carry their real weight stack, odd steps included, an
