The Amazfit Helio Strap Pro is a revolutionary screen-free fitness tracker designed specifically for hybrid athletes and HYROX competitors, launching globally on June 25, 2026. Its defining feature is a dual-sensor system comprising a wrist/arm heart rate module and a unique 9-axis waist pod, which together provide unmatched accuracy for functional movements like sled pushes and wall balls. Priced at $199.99 with no monthly subscription, it offers up to 44 days of battery life on the waist module and integrates deeply with the Zepp app for recovery and sleep tracking. While currently limited to HYROX-specific modes for the waist sensor and requiring a compatible Amazfit watch for full features, it represents a significant leap in movement intelligence for serious trainers.
What Is the Amazfit Helio Strap Pro?
The Amazfit Helio Strap Pro is a specialized, screen-free fitness tracker built to understand how your body moves during intense training. Unlike standard smartwatches that rely solely on wrist data, this device uses a dual-sensor system to capture a complete picture of your physical exertion.
Most trackers fail to accurately measure effort during functional fitness because your wrist often stays still while your body works hard. The Amazfit Helio Strap Pro solves this by combining the Helio Core Motion HR module worn on the wrist or upper arm with the Helio Core Motion Waist module clipped to your waist. This setup allows it to track your heart rate and your center of mass simultaneously.
This system was engineered with HYROX in mind, a global fitness racing series. It supports eight specific HYROX events right out of the box, including the SkiErg, Sled Push, and Wall Balls. At launch, the advanced waist sensor is optimized specifically for “HYROX Race” and “HYROX Simulation” modes, providing data that matches actual competition conditions.
Design and Comfort: Built for Movement
The Amazfit Helio Strap Pro is designed to be unobtrusive, lightweight, and durable enough for the toughest workouts. Its compact form factor ensures it stays out of your way while you train.
- Compact Dimensions: Both the HR and waist modules measure approximately 34mm x 24mm, making them small enough to forget you are wearing them.
- Versatile Wear Options: The package includes an olive gray and orange nylon wristband and a charcoal black nylon armband, allowing you to wear the HR sensor on your wrist or upper arm for better accuracy.
- Customizable Bands: It features a standard 22mm band size, meaning you can easily swap in your own favorite watch straps.
- Water Resistance: With a 5 ATM rating, the device is safe for swimming, showering, and heavy sweating.
Since there are no buttons or screens, interaction is handled via the companion app or automatic detection. The device supports open Bluetooth connectivity, letting you pair it with third-party bike computers or gym equipment to start workouts seamlessly.
The HYROX Advantage: Why Two Sensors Matter
The primary reason to choose the Amazfit Helio Strap Pro is its ability to accurately track complex hybrid movements that confuse traditional watches. By adding a waist sensor, it captures data from your body’s center of mass.
How the Dual-Sensor System Works
Traditional wrist trackers often misinterpret exercises like farmer’s carries or sled pushes as rest because your arm isn’t swinging. The Helio Core Motion Waist module fixes this by using a 9-axis IMU (Inertial Measurement Unit) to track your core movement.
- Center of Mass Tracking: The waist clip monitors the movement of your hips and torso, which remains consistent across all types of exercise.
- Improved Rep Counting: For movements like wall balls, the system detects squat depth and standing motion more precisely than a wrist sensor alone.
- Venue Geometry: The system utilizes venue geometry data to understand track layouts, though full data availability is still being refined at launch.
Current Limitations and Future Updates
At launch, the powerful waist sensor is active only during HYROX Race and HYROX Simulation modes.
- Calibration Required: Users must calibrate the waist sensor before every session to ensure accurate movement analysis.
- Future Modes: Amazfit has confirmed that broader support for other workout types is coming, but no specific timeline has been provided yet.
- Compatibility: To access these advanced HYROX features, the strap must be paired with an Amazfit Balance 3 or Balance Ultra watch.
Battery Life: Power That Lasts
One of the most impressive aspects of the Amazfit Helio Strap Pro is its exceptional battery life, enabled by the lack of a power-hungry display. The two modules have different battery capacities optimized for their specific roles.
| Module | Battery Life | Usage Context |
|---|---|---|
| Helio Core Motion HR | Up to 11 days | Continuous heart rate and activity tracking |
| Helio Core Motion Waist | Up to 44 days | Intermittent use during HYROX modes |
Real-world testing suggests the HR module typically lasts 8 to 10 days with mixed usage, which is still far superior to most smartwatches. The waist module lasts over a month because it primarily activates during specific tracking sessions. Charging is simple with the included magnetic charging head, which snaps easily onto the back of either module.
Health and Recovery: More Than Just Workouts
Beyond tracking workouts, the Amazfit Helio Strap Pro serves as a comprehensive health monitor through the Zepp app. It provides deep insights into your recovery status, sleep quality, and overall readiness.
Sleep Tracking
The device offers detailed sleep stage analysis, including deep sleep, light sleep, and REM sleep.
- Accuracy: Early data indicates a 60-70% agreement with medical-grade polysomnography tests.
- Health Insights: It includes a sleep apnea risk assessment to help identify potential breathing issues during rest.
- Awake Detection: The tracker can detect periods of wakefulness during the night, helping you understand sleep fragmentation.
BioCharge Recovery
To guide your training intensity, the system uses the BioCharge algorithm to generate a daily recovery score from 0 to 100.
- Score Interpretation: A high score indicates your body is recharged and ready for hard effort, while a low score suggests a need for rest.
- Data Sources: The score is calculated using Heart Rate Variability (HRV), sleep quality, and recent exertion levels.
Food Tracking and Heart Rate
Nutrition and heart rate accuracy are also key components of the health suite.
- Photo Food Logging: The Zepp app allows you to take photos of your meals for automatic calorie and food identification.
- BioTracker 6.0: The HR module uses a new sensor with 5 photodiodes and 2 LEDs, offering accuracy comparable to the Whoop 4.0.
- Upper Arm Option: Wearing the sensor on the upper arm (using the included band) can further improve accuracy during high-intensity lifting.
App Experience and Connectivity
The Amazfit Helio Strap Pro relies on the Zepp app (available on iOS 17+ and Android 8+) to visualize data and manage settings. While the hardware is robust, the software experience has both strengths and areas for growth.
