Apple Watch keeps pausing during workouts

Hi

Check that Wrist Detection is turned on:

- On your iPhone, in the Watch app, go to: My Watch (tab) > General > Wrist Detection.

If Passcode is enabled, check also that you are unlocking your watch after placing it on your wrist.

Tracking can be affected if your watch loses contact with your skin, causing it to believe that it has been removed from your wrist. This would cause the Workout app to pause automatically.

A loose fitting band can trigger this by allowing your watch to lift from your wrist and/or by allowing clothing (for example, the end of a sleeve) to slip beneath the back of the watch. Sensor performance can also be affected by temporary or permanent changes to your skin, such as some wrist tattoos.

During exercise, Apple Watch should be worn snugly on the top of your wrist. Apple suggests that you consider tightening your band before workouts and loosening it again afterwards. Better contact with your wrist may also improve heart rate sensor performance during your workout.
