Amazfit Helio Strap owners who found the workout list too narrow are getting a sizable fix: firmware 3.22.0.1 adds 51 new workout modes and is now rolling out worldwide in phases.
The update, about 3.7 MB, was detailed in release notes shared by a Reddit user and reported by Notebookcheck. It also includes a VO2 Max algorithm update, unspecified bug fixes, and system stability improvements for the fitness tracking wearable released in 2025.
Amazfit Helio Strap firmware 3.22.0.1 rolls out worldwide with a bigger workout menu
The headline change is simple: 51 additional workout modes. Amazfit has not published the full list in the available release notes, but the company says the new options include indoor workouts, dance-related exercises, and ball sports.
That matters because users previously had fewer activity labels to choose from. With more sport profiles, a training session is less likely to end up filed under a generic category that tells the app little about what actually happened.
The rollout is global, but not instant. Firmware 3.22.0.1 is being distributed in phases, so Helio Strap users may see the update appear at different times depending on region and app availability.
Users can download the firmware through the Zepp smartphone app once it appears for their device. The practical install checklist is straightforward:
- Check: Open the Zepp app and look for the Helio Strap firmware update.
- Charge: Keep the strap sufficiently powered before starting.
- Connect: Maintain a stable Bluetooth connection during installation.
- Confirm: After installation, verify that the device shows firmware 3.22.0.1.
Amazfit has not said whether the rollout schedule differs by country or account type. For now, “rolling out in phases” is the only confirmed timing detail.
New Helio Strap sports profiles make messy training logs less messy
The most visible upgrade is not a new sensor or a new device. It is classification.
More workout modes let users describe sessions with greater precision. That can make the workout history cleaner, especially for activities that previously had to be squeezed into broad labels.
| Firmware detail | Confirmed in this release |
|---|---|
| Device | Amazfit Helio Strap |
| Version | 3.22.0.1 |
| Update size | Around 3.7 MB |
| New workout modes | 51 |
| Examples of categories | Indoor workouts, dance-related exercises, ball sports |
| Delivery | Zepp smartphone app |
| Rollout | Phased worldwide release |
Analysis: The upgrade is most useful if users train across varied activities. A runner who only logs one sport may not notice much beyond the expanded menu. Someone switching between gym work, indoor training, dance classes, and ball sports gets a better-organized record.
That is the safe read. The release notes support better activity selection. They do not confirm better sensor accuracy for those activities.
Amazfit’s previous Helio Strap update gives useful context. In a December 2025 software note, Amazfit said firmware 3.7.0.1 added 29 new workout modes, favorite workout shortcuts, improved activity recognition, and better Balance 2 connectivity, according to Amazfit. The new 51-mode update suggests Amazfit is still expanding the strap’s software coverage after launch.
MLXIO has been tracking that wider push around Amazfit wearables, including ECG Patent Turns Amazfit Helio Ring Into Health Bet and 3 Amazfit Smartwatches Turn iPhone Alerts Into Action. The Helio Strap update fits the same broad pattern: more capability arriving through software rather than a new product announcement.
VO2 Max tweak could change fitness readings, but Amazfit has not shown the math
Firmware 3.22.0.1 also updates the VO2 Max algorithm. That is potentially more consequential than the workout menu, but Amazfit has not explained what changed.
VO2 Max estimates how efficiently the body uses oxygen during hard exercise. Wearables use it as a proxy for cardiovascular fitness and endurance progress. Changes to the algorithm can affect how users interpret training trends.
The problem: the release notes do not say whether the update improves accuracy, changes weighting, adjusts supported workouts, or smooths noisy readings. So this should be treated as a metric improvement, not a confirmed overhaul.
Users should watch their own data after updating. If historical readings stay fixed but new workouts generate different estimates, the change may only affect future calculations. If the app recalculates prior data, trend lines could shift.
Amazfit has not said either way.
Analysis: For athletes who use VO2 Max as a planning signal, the best response is patience. Track several sessions after installing 3.22.0.1 before assuming a higher or lower number reflects a real fitness change.
Helio Strap users should verify the update before trusting new trends
The first thing to watch is availability. Since the rollout is phased, some users will not see firmware 3.22.0.1 immediately in the Zepp app.
After installation, users should review the expanded workout list and confirm which of the 51 new modes actually appear on their device. The source material does not include the complete list, so early user reports may fill that gap before Amazfit publishes more detail.
The main post-update checks are practical:
- Battery behavior: Look for any unusual drain after installation.
- Syncing: Confirm workouts still transfer cleanly through Zepp.
- Workout list: Check whether relevant indoor, dance, or ball sport modes are now available.
- VO2 Max trends: Compare new readings against recent sessions, but avoid overreacting to one workout.
- Stability: Watch for the unspecified bug fixes and system improvements to show up in daily use.
No successor has been confirmed in the available source material, so this firmware release keeps the current Helio Strap moving for now. The next useful signal will be either a fuller Amazfit changelog or enough user feedback to identify the new workout modes and the real effect of the VO2 Max adjustment.
Key Takeaways
- Helio Strap users get 51 new workout modes, making activity tracking more specific.
- The update also improves the VO2 Max algorithm, bug fixes, and system stability.
- The global phased rollout means availability may vary by region and device timing.
