I Forgot to Start My Workout on My Watch
Finished a session but forgot to hit start on your wearable? Here's what your options are.
I Forgot to Start My Workout on My Watch
It happens. Here’s what you can do depending on your device.
Option 1 — Check if Your Wearable Auto-Detected It
Some wearables automatically detect and log workouts even without a manual start. Check your wearable app before assuming the session is lost.
| Device | Auto-detection |
|---|---|
| Apple Watch | Yes — checks for 10+ minutes of elevated activity and prompts you retroactively |
| Garmin | Yes — many models auto-detect common activities (running, cycling) |
| Fitbit | Yes — auto-detects 10+ minutes of continuous activity |
| WHOOP | WHOOP tracks continuously — check the Strain tab for the session |
| Oura | Oura detects activity automatically — check the Activity tab |
| Samsung | Auto-detect on Galaxy Watch models |
| Amazfit / Xiaomi | Auto-detect on supported models — check Zepp app |
If the workout appears in your wearable app (even as auto-detected), it will sync to NestEgg normally. Wait a few minutes and pull to refresh.
Option 2 — Use Photo-Upload
If no workout was recorded by your wearable, photo-upload is the alternative. You’ll need approximate data for the session:
- Workout type — what you did
- Date and start time — as accurate as you can recall
- Duration — total session length in minutes
- Average Heart Rate — this is the tricky one
Finding approximate Avg HR without a recorded workout:
- Fitness tracker with continuous monitoring: Some devices track HR continuously even outside workouts. Check your wearable app for HR data during the time window of your session.
- Smartwatch health data: Apple Health, Samsung Health, and Garmin Connect store continuous HR readings. Look for the period during your session.
- Educated estimate: If you genuinely have no HR data, you can estimate based on how hard you were working — but this is imprecise and will affect your score accuracy.
See How to Photo-Upload a Workout for the full upload flow.
Option 3 — Accept the Miss
If you can’t reconstruct accurate HR data, it may not be worth uploading with guessed values — inaccurate data produces inaccurate scores. One missed workout isn’t the end of a challenge.
The system is designed to handle imperfect weeks. Your Level Score won’t plummet from one missed session — keep your streak going from the next workout.
Prevention
For Apple Watch users: Enable Workout Reminders in the Apple Watch Workout app settings. The watch will tap you on the wrist if it detects you’ve been exercising without starting a workout.
For all devices: Make starting your workout app part of your pre-exercise routine — same as putting on your shoes.
Common Questions
Can I upload a workout from last week? Workouts must be uploaded within the current scoring period to count toward that period’s score. A workout from a closed period won’t contribute retroactively. Check with your challenge organizer if you’re unsure of the cutoff.
My wearable auto-detected the workout but shows it as a different type. That’s fine — you can edit the workout type in NestEgg after it syncs. See My Workout Type Is Wrong.
