01
Log sessions
Fill in reps and weight as you go — fast, no fuss. Target and last result stay visible; max weight, total volume, and est. 1RM calculate themselves.
Notebook Gymbros
Your gym spreadsheet, as an app.
Log · Program · Week in one workbook — dual current/last values, Schemes A/B/C, graphs, and export when you need the file.

The problem
Spreadsheets work — until you're under the bar.
Templates scatter across Drive. Formulas break. Phone logging means squinting at rows while the rest timer runs. Notebook Gymbros keeps the workbook mental model and makes it usable in the gym.
Features
Everything your Excel training file already does — on your phone.
02
Your program, built by you
Set it up the way a coach would — sets, reps, and Schemes A/B/C for every exercise. Max, volume, and est. 1RM fill from your log.
03
Plan your week
Lay out Monday to Sunday — program, scheme, and notes for each day. Your training plan at a glance, week by week.
04
Build your exercise library
Start from our library or add your own in seconds — by muscle group, with sets, reps, and RIR per scheme, plus supersets by grouping rows.
05
See your progress
Visual view of programs and schemes A–C, auto-populated from your log — track max weight, total volume, and est. 1RM over time.
06
Your data, your control
Export CSV or XLSX, back up to the cloud, print PDF, share program templates by Template ID, and manage programs and settings securely.
Health & import
Bring your history. Keep your notebook.
Connect Apple Health or Google Health, import set-level logs from the big strength apps, sync activity from Strava and friends, and get reminded to log — without losing the spreadsheet model.
Health platforms
iOS: Apple Health. Android: Google Health Connect. Scan strength sessions, write Notebook sessions back, and keep body-mass context in the OS hub.

Export & cloud backup
CSV training log, full XLSX workbook, PDF print, and cloud backup — the sheet you started from, portable.
Hevy Pro live sync
Paste your Hevy Pro API key for live workout sync with set-level data. CSV works for everyone else.
Log reminders
Schedule on-device training reminders with the Notebook Gymbros icon. Local notifications — not cloud push.
How it works
Three steps. Same mental model as your workbook.
- 01
Build the program
Lay out blocks and Schemes A/B/C the way you already do in a sheet. Computed Max / Vol / RM stay visible.
- 02
Log the session
Enter sets under the bar with dual current/last values, RIR and RPE. Hide unused sets; the grid autofills from your block.
- 03
Watch progress
Open graphs for weight, volume, and estimated 1RM. Export CSV/XLSX, print, or share program templates when you need to.
