openGym

A self-hosted gym and body-weight tracker you actually own.

Plan your week, run guided workouts, log every set and your body weight, on your phone, synced across your devices, behind your own passkey login.

Features:

Planning

• A routine per weekday over a library of 1,324 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.
• 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.
• 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.

Progress

• Progression rules per routine or per exercise: linear, Greyskull LP, double progression through a visible rep range, or adding time. Each target explains why it is that number; missed reps never add load, stalls trigger a deload.
• Estimated 1RM per exercise with its own curve, Structural Balance ratios (Poliquin, Thibaudeau, ATG), a year-long activity heatmap.
• A muscle map in three modes: where your volume went, what is still recovering, and what has gone untrained.
• Body-weight chart against a goal line, and progress photos on a timeline with a before/after slider.
• Edit any saved workout after the fact, log one you did on paper, or move it to the right date. Records are re-read from the corrected history.
