Get Started with Apple Health on Movement Rebels

Your iPhone and your Apple Watch are already collecting a pile of training data. Most of it sits there doing nothing. Movement Rebels reads that store and writes your next session out of what it finds. This guide covers connecting Apple Health, what data we can see, and how the coach uses it.

What Apple Health is and why it matters

Apple Health is the store every health and fitness app on your iPhone and Apple Watch writes into. Workouts, heart rate samples, step counts: it all lands in one encrypted database instead of sitting locked inside whichever app happened to record it. Movement Rebels reads from that database. Only with your permission, and only the parts you tick.

Control is the point. You pick which apps see which data types, you can pull that access back whenever you want, and the store itself stays encrypted on the device and end-to-end in iCloud.

Setting up Apple Health permission for Movement Rebels

Open the app on your iPhone, where the prompt to connect Apple Health shows up on first launch and then lives in Settings for as long as you need it. Tap it.

The next screen asks to read workouts, heart rate, steps, distance, and heart rate variability (HRV), and you can approve the lot or pick out the ones you are comfortable handing over. Every type you leave off is a signal the coach has to guess at instead of read, so the more you allow, the sharper the plan gets.

Changed your mind later? iPhone Settings, then Health, then Data Access & Devices, then Movement Rebels, and toggle any data type on or off. Takes effect immediately. No reinstall.

What data Movement Rebels reads from Apple Health

Once connected, Movement Rebels can read:

• Workouts. Anything you log in the native Fitness app, plus anything from an app that writes workouts into Apple Health. Strava and many running apps do. Garmin syncs steps and heart rate but not full workout sessions by default. What lands on our side: workout type, duration, calories burned, heart rate through the session, and the GPS route when there is one.
• Heart rate. Continuous through a workout, plus the background samples the watch takes across the rest of the day without being asked, and the coach reads both intensity and recovery off those numbers.
• Steps and distance. Daily totals and per-minute samples. This is how the coach sees the load you carry outside of structured training, the walking and the standing that never gets logged as a workout.
• Heart rate variability (HRV). The variation between heartbeats. Older Apple Watch software captured it only during Breathe and Mindfulness exercises, while watchOS 9 and later also records HRV samples while you sleep, and either way the number ends up in Apple Health where the coach can read it. Higher HRV often correlates with readiness. One signal among many when the coach picks between a push day and a recovery day.
• Resting heart rate. A daily estimate built from overnight readings, and when it climbs you are either tired or getting sick, which is why the coach watches the trend instead of reacting to one bad morning.

One direction only. We read from Apple Health and never overwrite what is in there, though workouts you finish in Movement Rebels can be logged back to Health if you want them in both places.

How the coach uses this data

The coach reads every type you granted, and any one of them can move tomorrow's session.

Your Garmin or your Apple Watch shows a spike in resting heart rate, HRV drops overnight, the coach stops pretending you are recovered, and the hard interval session gets swapped for something shorter and easier instead of holding to the plan. Same after a soccer match or a pick-up basketball game logged in another app: that fatigue is real, it goes into the week's total, and the intensity comes down to match.

Step count sets your baseline. Ten thousand steps a day from a desk job is a different load from ten thousand out of a trade or service work, and the coach calibrates to which one you are.

The inputs are the workouts sitting in your history and the heart rate and HRV your watch recorded. No self-reported guesswork.

Syncing: automatic and reliable

After the permission prompt there is nothing to press. The app checks Apple Health in the background, new workouts show up within minutes, and heart rate and HRV samples arrive on their own while you get on with your day.

iCloud keeps it consistent across your devices, so a workout you log on the iPhone shows up on the iPad right away, assuming both sit on the same iCloud account.

All of it moves encrypted, at rest and in transit, and your health data never leaves the device in readable form, iCloud copies included. Apple handles that layer.

What data is not available from Apple Health

Apple Health only holds what other apps put into it, and wearables like Oura Ring and Whoop push some of their metrics across while holding the rest back inside their own apps. Oura does not currently write heart rate variability (HRV) data directly to Apple Health, and HRV is a core Oura metric. Same story on the other side: Whoop data does not include HRV syncing to Apple Health.

Apple's own HRV is a different animal. HealthKit captures different stress-recovery signals than Whoop's or Oura's sleep-based HRV, and older watchOS versions recorded it only during Breathe and Mindfulness exercises, though watchOS 9 and later samples during sleep too and closes part of that gap.

So read the documentation for whatever non-Apple wearable you run, because a metric that is missing from its sync list is a metric Movement Rebels will never see either. Check before you count on it.

Battery and performance

Does the syncing eat your battery? No, as long as your Health data is clean. Background refresh on Apple Health costs close to nothing on a healthy phone, and most people will never spot it in their battery breakdown.

The exception is a Health database that has gone corrupt or bloated. That one does drain. A factory reset and an iCloud restore clears it, and it stays rare enough that you should rule out other suspects before you go anywhere near a reset.

Sharing your Health data beyond Movement Rebels

Apple Health is a hub, so nothing you send it stays locked to one app. Strava activities land there. So does anything else with HealthKit support, all of it feeding the same store at the same time, which is why moving between apps never costs you your history. Garmin is the exception to watch. Steps and heart rate cross over, full workout sessions do not, at least not by default.

Privacy and who sees your data

Your passcode, Touch ID, or Face ID is what encrypts Health data on the device, which also means anyone holding your unlocked iPhone can read it. Medical ID sits outside that lock on purpose. Turn on two-factor authentication and the iCloud copy gets end-to-end encryption too.

We see the types you ticked. Nothing else. Delete something from Apple Health and it disappears from every synced device, with backups the only way back.

How Movement Rebels fits

Most athletes already know what a good week looks like on paper. The week you had is the problem. You ran hard yesterday, so today should be easy. You slept badly, so the plan moves. You put 25,000 steps in from work on top of a 15 km run, and the fatigue is real even if you feel fine.

Movement Rebels reads that load out of Apple Health and builds the week around it, so the heavy lifts land on days you have capacity for them and the easy days stay easy. Garmin data feeds the same picture if you run one, and a workout logged in any app on your phone reaches the coach the same way.

Connect Apple Health. Workouts and heart rate at minimum. Everything you share on top of that is one more thing the coach does not have to guess.
