Strength training
Training that keeps up with what your body actually did.
Most training apps hand you the same session whether you slept nine hours or four. STRAXE reads the recovery signals already sitting in Apple Health and sizes the day's work to match — then logs every set against a 500-exercise library.
Why it exists
A programme that ignores your recovery is a spreadsheet with opinions.
Progressive overload works, and every serious lifting programme is built on it. What almost none of them account for is the week you slept badly, travelled, or came back from being ill. The load keeps climbing on schedule, and you either grind through it or fall off the plan entirely.
STRAXE keeps the structure and makes the load answer to the data your watch has already collected.
What it does
Log the work. Follow the plan. Back off when your body says so.
500 exercises, filtered down to your gym
Search the whole library by muscle, equipment or category — or switch to My Gym so you only ever see what you can actually load. Every set, rep and weight is logged against the exercise, which is what makes the trends mean anything six months later.
- Filter by muscle group, equipment or category
- Eight built-in programmes, including 5/3/1 BBB and GZCLP
- Personal records tracked per exercise
Recovery Readiness, from data you already have
If you wear an Apple Watch, your heart-rate variability, resting heart rate and sleep are already being recorded. STRAXE reads those, compares them against your own baseline, and adjusts the day's prescribed load — rather than asking you how you feel and taking your word for it.
The screen above is that working: HRV came in at 16 ms against a 39 ms average, so the session was marked moderate effort and the header changed from Ready to train to Train controlled. Nothing was cancelled — the load was just sized to the day.
This is a rules engine, not a language model. The thresholds come from published strength and load-management research, the whole thing runs on your phone with no network call, and it reads from Apple Health only after you grant permission. The underlying figures stay in Health.
A streak that survives one bad week
Sessions earn XP and levels, and consecutive weeks build a streak. Miss one and a streak shield spends itself to keep the run alive — you can hold up to three. It's a small mechanic, but it's the difference between one missed week and quitting in February.
- XP and levels for completed sessions
- Up to three streak shields, earned at seven-day milestones
- An optional community of crews, challenges and leaderboards
You're 69% of the way there. Finish this week's sessions and you'll earn your first streak shield.
How strong is that, actually?
A number on a bar means very little on its own. STRAXE estimates your one-rep max from the sets you've logged and places it on a tier — Bronze through Elite — adjusted for your bodyweight, so you can see where a lift sits and exactly how much more it needs to reach the next one.
- Estimated 1RM per exercise, from your own logged sets
- A tier and percentile for each lift, scaled to your bodyweight
- How many pounds away the next tier is
- Thirty-day movement on every lift
The tiers come from published bodyweight-ratio benchmarks — ExRx and Symmetric Strength style tables built into the app — not from comparing you against other STRAXE users. There is no live database of other people's lifts behind this, and it isn't a competitive or clinical assessment. It's there for perspective.
STRAXE Pro
Free to train. Pro for the analysis.
Everything you need to actually run a programme — the library, the routines, the logging — is free and stays free. Pro is a subscription, because the recovery engine and the long-range trend analysis are the parts that keep working in the background and keep getting better the longer they run.
Free
- The full 500-exercise library
- Routines and built-in programmes
- Set logging and personal records
- 30 days of chart history
- Body weight and body-fat tracking
Pro $5.99/mo · $39.99/yr
- Recovery Readiness from Apple Health
- Per-muscle volume trends
- Fatigue and adaptation trends
- Full chart history, not just 30 days
- Body measurements and progress photos
- CSV export of everything you've logged
Pro is a subscription rather than a one-time purchase — it's the one app in the catalogue where that's true, and it's because the recovery engine earns its keep every week rather than once. If a free trial is running, its length is shown on the purchase screen in the app.
Built into the phone
On your wrist, on the Lock Screen, and out of your way mid-set.
Start a session and STRAXE puts a Live Activity on your Lock Screen and in the Dynamic Island — the current exercise and the rest timer, tappable without unlocking. Nobody wants to fight a phone between sets.
The Apple Watch app logs sets from your wrist and carries a complication, so the next session is on your watch face. Your workouts, routines, records and body metrics sync through your own iCloud and follow you to a new phone without an account.
Recovery Readiness reads heart-rate variability, resting heart rate and sleep from Apple Health, and only after you grant permission — you can revoke it in Health at any time. STRAXE is a training log, not medical or coaching advice; talk to a professional before starting a new programme. The privacy policy covers the optional Community in full.
