What you can (and can’t) customize on One UI 6
On One UI 6 for Galaxy Watch, you can create workouts that match your training structure (time, distance, reps, and interval blocks), then start them from the watch with live metrics.
What changes from watch to watch is how granular the workout builder is (for example, whether you’re building a run/walk interval layout vs a more general “custom” timer-style session). The steps below cover the common Samsung Health pathways and the settings you’ll actually see.

Prerequisites before you start
Before you create or edit custom workouts, confirm these items so you don’t waste time troubleshooting permissions and sync.
- Galaxy Watch with One UI 6: Verify in Settings > About watch (or Software information). Some menu wording varies by model.
- Samsung Health installed on the watch, and updated from the Galaxy Store (on watch) and/or Play Store (on phone).
- Workout permissions enabled: Samsung Health typically needs location for certain activities and sensor access for heart-rate-based metrics.
- Internet and sync (if building on phone): keep Bluetooth between watch and phone active during setup and initial sync.
- Battery considerations: if you use Battery saver/Power saving modes, background sync and data display can be delayed.
Method 1: Create a custom workout in Samsung Health (watch-first workflow)
If you want the fastest path—build it on the watch, then start it immediately—this workflow is usually the most reliable.
Choose your workout type (and what ‘custom’ means here)
Custom workout features commonly start from a general “workout” flow and then let you configure segments/intervals. On your watch, open Samsung Health and go to the workouts area.
- Open Samsung Health on the watch.
- Tap Workouts (or Exercise, depending on your layout).
- Tap Create, +, or Add.
- Select the workout category closest to your goal (for example, Running, Walking, Cycling, Strength, or Custom/Interval).
If you only see built-in workout categories, choose the one that matches your activity type, then use the interval/segment options in the next steps. In many One UI 6 builds, that’s where “custom” becomes real.
Build the workout: intervals, reps, distance, and timers
Look for a builder that offers blocks like Warm-up, Work, Rest, and Repeat. Use time-based intervals for consistency; use distance/reps when you already pace by splits.
- In the workout builder, set your Warm-up (commonly as Time, or optionally as Distance depending on activity type).
- Add a Work segment and choose the measurement: Time, Distance, or Reps (availability varies by workout type).
- Add a Rest segment.
- Set Repeat count (for example, repeat 6 times).
- If the builder offers it, add a Cool-down block.
- Confirm units and values carefully before saving (e.g., minutes vs seconds; km vs miles; reps vs rounds).
Concrete example: A simple interval run might be Warm-up 10 minutes, Work 400 meters, Rest 200 meters, Repeat 8 times, then Cool-down 5 minutes.
Rank #2
- Larger Super AMOLED Display: Expanded screen area with slimmer bezels for improved visibility and usability.
Save and start the workout
Once the segments look right, save the workout and start it from your workout list.
- Tap Save or the checkmark icon.
- Name it (for example, 8x400m Tempo), if naming appears.
- From the workout list, tap your newly created workout.
- Tap Start.
- If prompted, choose how you want metrics displayed (heart rate, pace, distance, cadence—depends on your watch sensors and activity type).
Method 2: Build the workout in Samsung Health on your phone, then sync
If you prefer larger-screen editing, or if the watch builder is limited for your workout type, create the workout on your phone and let it sync to the Galaxy Watch with One UI 6.
Pairing and sync requirements
Phone-built workouts often fail to appear because syncing was interrupted or permissions weren’t granted. Handle that first.
- On your phone, confirm Galaxy Wearable (or Samsung’s watch companion app) is paired.
- Open Samsung Health on the phone.
- Verify Bluetooth is connected between phone and watch.
- Keep both devices awake and on Wi‑Fi/LTE long enough for the first sync after you create the workout.
Creating the custom workout on mobile
Samsung Health’s mobile UI is more likely to expose interval and segment options clearly.
- Open Samsung Health on your phone.
- Go to Workouts (or Exercise).
- Select Create, +, or Add workout.
- Choose the workout category that matches your plan (run/interval, strength/sets, etc.).
- Set warm-up, work/rest blocks, repeat count, and cool-down.
- Save the workout.
After saving, the workout should be pushed to the watch during sync. If you just saved it, give it 1–5 minutes (faster if the app is active and Bluetooth is stable).

Confirming the workout appears on the watch
- On the watch, open Samsung Health.
- Go to Workouts and scroll to your custom workout.
- If it’s not there, force a sync by reopening Samsung Health or toggling watch Bluetooth briefly (keep it safe and quick).
If you still don’t see it, use the troubleshooting steps later in this guide.
Rank #3
- Rotating Bezel Design: Classic rotating bezel enables precise control and smooth navigation.
Method 3: Use interval/segment workouts directly on the watch
Some One UI 6 layouts make it easier to build segments from an interval mode rather than a generic custom workout builder.
Configure step-by-step interval blocks
- Open Samsung Health on your watch.
- Tap Workouts.
- Select Interval, Custom intervals, or the closest labeled mode.
- Set Number of sets (how many “repeat rounds”).
- For each segment, choose the measure type (time/distance/reps) and enter values.
- Confirm the watch shows the total plan correctly (some builders show a mini timeline preview).
- Tap Save.
Handling warm-up/cool-down segments
Many interval templates assume warm-up and cool-down are optional, but you’ll get better pacing and fewer “surprise” triggers if you include them explicitly.
- Warm-up: 5–15 minutes depending on your activity and intensity.
- Cool-down: 5–10 minutes or until your heart rate drops toward a comfortable range.
- Rest accuracy: if rest is active, include it as a measured segment (not just “pause”).
Method 4: Edit, duplicate, and manage custom workouts
Custom workouts aren’t just for one-off sessions. Once you set them up, you’ll likely tweak interval values and repeats as your training changes.
Edit an existing workout
- Open Samsung Health on the watch.
- Go to Workouts and locate your custom workout.
- Tap and hold (or open the workout details screen) and choose Edit.
- Adjust segment values, repeat count, or measurement units.
- Tap Save.
Gotcha: If editing on the phone and the watch simultaneously, the last sync may overwrite changes. Stick to one editing location at a time.
Duplicate for quick reuse
When you need “the same workout, different numbers,” duplication saves time and reduces mistakes.
- Open Workouts on the watch.
- Open the workout’s details.
- Select Duplicate (or Copy).
- Rename it (for example, 8x400m 5k Pace).
- Edit only the segments you changed, then save.
Rename, remove, and troubleshoot missing workouts
If you remove a custom workout and later try to start it, it won’t be recoverable unless you recreate it (or re-sync from the phone if that copy still exists).
Rank #4
- Rotating Bezel Design: Classic rotating bezel enables precise control and smooth navigation.
- To rename: open workout details > Edit > update name > Save.
- To remove: workout details > Delete > confirm.
- If a workout disappears: check Samsung Health sync status and ensure Samsung Health isn’t restricted from background activity.
Troubleshooting when custom workouts won’t save or show up
Custom workout problems usually come down to permissions, sync state, or inconsistent units (minutes vs seconds, km vs miles).
The Tool Desk
Outbyte Driver Updater FREEScan for outdated or missing drivers - takes under a minuteDriver Scan →Outbyte PC Repair FREERepair Windows errors before they cause bigger problemsFix Now →Workout won’t start (stuck on loading, permissions, or sensors)
Try these checks in order.
- Close and reopen Samsung Health on the watch.
- Restart the watch (hold the side button, restart).
- Confirm sensor permissions for the relevant activity (heart rate, location if required).
- Test a built-in workout of the same type to confirm sensors are working.
- Update Samsung Health on the watch from Galaxy Store if an update is available.
Workout saves but doesn’t appear on the watch
- On the watch, open Samsung Health and refresh the workouts list.
- On the phone, ensure the watch companion app is connected to the watch.
- Toggle Bluetooth off and back on for both devices, then wait 1–3 minutes.
- Check if Power saving is enabled on either device.
- Confirm the same Samsung account is used for Samsung Health data syncing.
If you recently changed accounts or reset your watch, the sync can take longer. Give it a bit before recreating the workout.
Interval settings aren’t applying (wrong duration/unit)
This is common when you build on phone and edit later on watch.
- Time units: check whether your input is set to minutes or seconds.
- Distance units: verify km vs miles (some phones switch based on locale).
- Repeat meaning: some builders interpret repeat as “number of blocks” while others interpret it as “number of rounds.”
Before the first interval starts, pause and verify the displayed segment info. If it looks wrong, stop and edit before you get deep into the workout.
Battery saver and background limits
One UI 6 devices can aggressively limit background activity when Battery saver is on. If your custom workout sync is delayed, temporarily disable Battery saver on the watch.

Common mistakes that waste time (and how to avoid them)
- Using the wrong workout category: pick the type that exposes the interval/segment controls you need.
- Leaving rest undefined: if rest isn’t configured, your watch may behave like a continuous activity.
- Overcomplicating segments: for your first custom build, start with 3–4 blocks (warm-up, work, rest, cool-down).
- Forgetting repeats: verify repeat count before saving. It’s easy to save a plan with repeats set to 1.
- Not testing: run a short “dry run” session (e.g., 2 repeats) to validate the pacing prompts.
Comparison: Custom workout vs built-in workouts vs training plans
Custom workouts are best when you need a specific structure you don’t want to guess during a session. Built-in workouts are best for common goals with minimal setup. Training plans are best for progressive scheduling.

FAQs about custom workouts on Galaxy Watch with One UI 6
Do I need Samsung Health Premium to create custom workouts?
Usually, custom interval/segment workout creation is available in the standard Samsung Health experience. Some advanced training plan features may require premium services, but the core interval workout builder is commonly accessible without upgrading.
Will my custom workout track GPS/pace on One UI 6?
If your workout type uses location (for example, Running outdoors), the watch will typically use GPS and show pace/distance. If you build a time-only or indoor-focused workout, you may not need location.
Can I use my custom workout during indoor treadmill sessions?
Yes, if you select a treadmill-appropriate workout type or build the plan using time/reps rather than GPS distance. For distance-based intervals indoors, accuracy depends on treadmill calibration and your input method.
Recommended Free Tools
Why do my intervals trigger at the wrong times?
Most often this is a units mismatch (seconds vs minutes, km vs miles) or a repeat interpretation issue. Edit the workout, double-check the segment preview/timeline, and run a short test before committing to a full session.
How do I make sure the workout syncs from phone to watch?
Keep Bluetooth connected, ensure Samsung Health isn’t restricted from background activity, and avoid powering down one device immediately after saving the workout on your phone.
Bottom Line
On Galaxy Watch with One UI 6, setting a custom workout is mostly about using Samsung Health’s workout builder correctly: pick the right workout type, configure warm-up/work/rest/repeats, and save with verified units.
If your workout doesn’t appear or won’t start, focus on the basics—sync state, sensor permissions, and Battery saver limits—then rebuild with simpler blocks and test quickly.
