Apple's Workout types article lists every workout the Workout app can record, and a missing workout is usually the wrong type, a session that never started, or Wrist Detection off. Open the Workout app, choose the type that matches what you are doing, and start it: Outdoor Run, Indoor Run, Pool Swim, Open Water Swim, HIIT, Functional Strength Training, Traditional Strength Training, Skiing, Wheelchair pace and more.
If yours is not listed, choose Other, or add a workout. The Activity app credits Move and Exercise by arm motion and the accelerometer; the Workout app can also use the heart rate sensor and GPS. Apple adds that during walks you should let the watch arm swing, or use Outdoor Walk when pushing a stroller. An Exercise minute needs movement equal to a brisk walk, worked out from your fitness level, and swimming and cycling count.

Model-specific
What is true of this model and not of its siblings
- Workouts by model
- Apple's tech specs list running, cycling, swimming, HIIT, strength training and more on every current model; the Ultra 2 adds a dive computer, depth gauge and water temperature sensor, and the SE 2 lacks the ECG and blood-oxygen sensors.
- Storage by model
- Workout data is small, but the Series 9, 10 and Ultra 2 have 64GB and the older models 32GB per Apple.
- Repair cost
- Missing workouts cost nothing to fix. A watch that cannot save workouts after a restart is a hardware or software fault; Apple's out-of-warranty battery service is $99, and repair fees ran from $199 for an SE 2 to $499 for an Ultra at launch, per MacRumors.
- Other models this page answers
- These steps also fit models Apple Watch Ultra, Apple Watch Series 9, Apple Watch Series 8, Apple Watch Series 7, Apple Watch Series 6.
Stop boundary
When this stops being a self-service repair
- !If workouts never save even after a restart, book Apple service
- !If only distance is wrong, calibrate outdoors, using Apple's calibration steps
- !If a session is lost after an update, wait for it to sync to the iPhone
