Frequently Asked Questions


How do I capture Hybrid Training Dynamics during HYROX training?

Hybrid Training Dynamics is designed to help athletes better understand how movement, muscle load, cardio effort, and performance evolve throughout HYROX training.To capture Hybrid Training Dynamics, athletes pair:

  • A Balance 3 or Balance Ultra on the wrist to track heart rate, overall performance, and movement throughout training.
  • A Helio Core Motion HR in the armband on the opposite arm to provide continuous heart-rate tracking during demanding exercises where wrist movement may impact accuracy.
  • A Helio Core Motion waist sensor using the waist clip to measure posture, stability, and full-body movement efficiency.

Once the system is set up, athletes select HYROX Race or HYROX Simulation Mode and begin training.During the workout, the Hybrid Training System works together to capture how the body responds throughout each stage of training:

  • Balance devices and the armband track heart rate and cardio effort
  • The arm sensor captures arm drive, movement patterns, and upper-body load
  • The waist sensor measures posture, stability, and overall movement efficiency as fatigue builds across disciplines

After training, data is brought together inside the Zepp App, where athletes can review Hybrid Training Dynamics insights including:

  • How muscle load changed across each station
  • How movement quality shifted under fatigue
  • Where efficiency improved or declined throughout training

By understanding how movement changes over time, athletes can refine technique, manage training load, and build greater consistency across strength, endurance, and recovery.

Does Helio Strap Pro require a subscription?

No. Helio Strap Pro works with the Zepp App and provides access to Hybrid Training Dynamics, training, recovery, health, and performance insights without a required monthly subscription.

Can Helio Strap Pro broadcast real-time heart rate?

Yes. Helio Strap Pro can broadcast real-time heart rate to compatible Amazfit smartwatches, cycling computers, fitness equipment, and supported training apps.

Can I wear Helio Strap Pro on my upper arm?

Yes. Helio Strap Pro is designed to be worn on the upper arm for training and can also be worn on the wrist for everyday health and recovery monitoring. As part of its multi-position system, it can also be integrated into supported waist-mounted configurations during select training experiences.

How is Helio Strap Pro different from a smartwatch or screen-free band?

Helio Strap Pro is designed specifically for Hybrid Training. In addition to continuous heart rate tracking, it captures movement quality, muscle load, and cardio effort to provide deeper insight into how the body performs throughout training. Unlike a smartwatch, it focuses entirely on data collection and performance analysis rather than notifications, apps, or on-device interaction. It complements a smartwatch by extending tracking when a watch is charging, not being worn, or impractical during certain activities.

Is Helio Strap Pro suitable for workout heart-rate tracking?

Yes. Helio Strap Pro is designed for workout heart-rate tracking across activities such as running, cycling, strength training, conditioning, and HYROX training. Its arm-worn position helps reduce movement interference during exercise while supporting more advanced performance analysis through the Hybrid Training System.

Is Helio Strap Pro a replacement for a chest strap?

For most athletes, yes. Helio Strap Pro provides continuous optical heart-rate tracking from the upper arm while also capturing movement and performance data that extend beyond heart rate alone. For many training activities, it offers a more comfortable alternative to a chest strap.

Does it work with iPhone and Android?

Yes. Helio Strap Pro works with both iPhone and Android devices through the Zepp App.

Which apps can it sync with?

Helio Strap Pro data can be synchronized through the Zepp ecosystem and shared with supported fitness platforms, including Strava, TrainingPeaks, adidas Running, Runna, komoot, Relive, Apple Health, and more. Additional integrations may vary by region and platform availability.

How long does the battery last?

Helio Strap Pro provides up to 11 days of battery life under typical usage conditions.

NOTES

1. The battery life may vary according to the settings, operation conditions and other factors. So the actual result may differ from the laboratory data. Helio Core Motion HR: With all-day heart rate monitoring and automatic all-day blood oxygen monitoring enabled, measured once per second; assisted sleep monitoring and stress monitoring enabled; sleep breathing monitoring enabled for 8 hours per day; training 3 times per week, 1 hour each time; Bluetooth connection and data sync once after each training session, with each sync lasting 1 minute.Helio Core Motion Waist: In daily use, the system remains in sleep standby mode and Bluetooth is disconnected; training 3 times per week, 1 hour each time; after each training session, Bluetooth is connected and data is synced once, with each sync lasting 1 minute.

2. According to the ISO 22810:2010 standard, the Amazfit Helio Strap Pro achieves a rating of 5 ATM, for a water-resistance of up to 50 meters, and is therefore suitable for splashes, snow, showering, swimming. It has passed third-party testing conducted by SGS, and the report number is SHES260400691471. Remove the strap when taking a hot shower or trip to the sauna, since too much steam can affect the seal and make it less water-resistant in future. For more information, please visit the support page at: support.amazfit.com

3. The material used for the packaging box is 100% recyclable, with naturally degradable materials including mineral-free inks and anodized aluminum used in the bronzing process.

4. Smart recognition of strength training exercises can only be engaged within the Strength Training sports mode. 25 exercises are able to be recognized at time of product release, including: Bodyweight squats, Bodyweight straight arm front squats, Barbell squats, Tricep pushdowns, Bent over rows, Barbell bench press, Sit-up holds, Knee-touch sit-ups, Dumbbell flys, Burpees, Burpee jumps, Overhead tricep extensions, Lying tricep extensions, Lateral raises, Jumping jacks, Lat pulldowns, Deadlift, Push-up, Shoulder press, Pull up, Bicep curls, Seated cable rows, Dumbbell drag curls, Straight-arm pulldowns, Russian twists. If an exercise is not auto-recognized by watch, the Zepp App can provide a list of muscle groups or exercise names to choose from. Training templates and interval training templates are compatible with: Strength training, Outdoor running, Treadmill, Outdoor cycling, Indoor cycling, Rope skipping, Rowing machine, Indoor fitness, Core training, and Stair climbing.

5. Connection to peripheral Bluetooth devices only supports devices with BLE connection.

6. Fitness app availability may vary depending on your country or region.

7. This product and the Zepp App are not medical devices and cannot be used for medical purposes, or as basis for diagnosis of any medical condition. Detection results are provided for reference only. Please consult professional medical institutions if you feel unwell. 24-hour monitoring of heart rate and blood-oxygen saturation (SpO₂) need to be enabled in the Zepp App. Abnormal heart rate alerts and the preset value need to be set in the Zepp App. To measure blood-oxygen saturation (SpO₂), please wear the device tightly at one finger-width from the wrist, and keep your arm still for best results. SpO₂alerts are sent if the detected rate is too low compared to the preset value, which needs to be set in the Zepp App, at a minimum of 80%. Movement, and environmental and physical characteristics can affect speed and accuracy of monitoring and measurement. The 24-hour stress level monitoring needs to be enabled in the Zepp App. Alerts for high stress levels are based on the preset value. Smart health alerts need to be enabled in the Zepp App. To process the one-tap measurement and other manual metric measurements, please wear the device tightly at one finger-width from the wrist, and keep your arm still for best results. Movement, and environmental and physical characteristics can affect speed and accuracy of monitoring and measurement.

8. Sleep monitoring can record night sleep and naps that last more than 20 minutes. Sleep Breathing Quality tracking needs to be enabled in the Zepp App.
