Stop auto workout segments

Hello Dragonflyhasquestions,

Welcome to Apple Support Communities. 

Please use the steps as listed here to customize your workout: Customize workouts on Apple Watch - Apple Support

Add warmup, work, recovery, and cooldown intervals

You can tailor your workouts to include a warmup period, repeating work and recovery intervals, and a time to cool down.

1. Open the Workout app  on your Apple Watch.
2. Turn the Digital Crown to the workout you want to do.
3. Tap , scroll to the bottom, then tap Create Workout.
4. Tap Custom, where you can do the following:

• Add a warmup period: Tap Warmup, then tap Time, Distance, or Open. You can also add a heart rate alert to the warmup period.
• Add work and recovery intervals: Tap Add, tap Work or Recovery, then choose Time, Distance, or Open.
  • You can add multiple work and recovery intervals.
  • Add a cooldown period: Tap Cooldown, then tap Time, Distance, or Open. When you choose Open, you can also add a heart rate alert.
  • Name the workout: Tap Untitled below Custom Title, then enter a name.

Note: If you’re doing a stationary workout—Elliptical or Pilates, for example—Distance isn’t an option.

• Tap Create Workout.
• The Create Workout button is active only if you’ve added a work or recovery interval.

If this isn’t what you were wanting to do, we recommend leaving feedback for Apple here: Feedback - Watch - Apple

Let us know if you have further questions.

Take care.
