Track every second. Recover every day. No subscription required.

Movement matters. Understand how your body performs, moves, and adapts through a complete Hybrid Training System built for serious athletes.

The Helio Strap Pro builds on the foundation of Helio Strap, adding advanced movement tracking through a multi-sensor system designed to capture more than effort alone. By combining heart rate, movement quality, and stability, it helps reveal how your body responds to stress, fatigue, and training demands. The result is a more complete understanding of cardio exertion, muscle exertion, and overall training load, helping athletes train with greater precision and control over time.

As part of the Hybrid Training System, the device captures performance and movement data throughout training, while the Zepp App brings those insights together afterward to connecting preparation, performance, and progression through one structured experience.

One System. A Complete View Of Performance.

Helio Strap Pro expands the Hybrid Training System through a multi-sensor setup across the watch, arm, and waist, creating a more complete view of how the body performs during training. Through Hybrid Training Dynamics, the system combines movement quality, muscle load, and cardio effort to show how strength, endurance, and recovery work together throughout each session.

For hybrid athletes, especially in demanding environments like HYROX, fatigue builds across disciplines before it becomes obvious. By understanding how movement influences efficiency and performance over time, the system helps bring greater precision and consistency to every workout.

Heart Rate Tells You Effort. Movement Tells You Execution.

Train every station with greater structure and precision. When paired with Balance 3 or Balance Ultra and activated within official HYROX Race or Simulation Modes, Helio Strap Pro helps athletes understand how movement, muscle load, and cardio effort evolve throughout training. As fatigue compounds across disciplines, the system helps reveal how the body responds over time, supporting more consistent execution and greater control.

Built Around Official HYROX Training.

Train every station with greater structure and precision. When paired with Balance 3 or Balance Ultra and activated within official HYROX Race or Simulation Modes, Helio Strap Pro helps athletes understand how movement, muscle load, and cardio effort evolve throughout training. As fatigue compounds across disciplines, the system helps reveal how the body responds over time, supporting more consistent execution and greater control.

One System. Three Roles.

Training
Strength training, HYROX Modes, & structured performance insights.
Movement
Movement quality, stability, and muscle load analysis.
Recovery
Sleep, HRV, recovery signals, and readiness insights.

See More Than Heart Rate

Movement and muscle load reveal the work behind the effort. Traditional heart rate data measures how the body responds to training stress. Helio Strap Pro extends that understanding by combining cardio load, movement quality, and muscle load to create a deeper view of performance throughout training.

Two athletes can complete the same workout while experiencing very different physical impact. Understanding how movement changes throughout a session provides a more accurate view of training stress, fatigue, and recovery needs.

The Intelligence Behind Your Progress

The Zepp App brings structure to training by connecting workouts, recovery, daily habits, nutrition, and performance trends into one continuous view of progress. As the intelligence layer of the Hybrid Training System, it transforms movement data into actionable insight, helping athletes train with greater balance, precision, and consistency over time, with no subscription required.

The Tracker You Can Wear When Your Watch Comes Off

Helio Strap Pro extends the Amazfit Hybrid Training System beyond the watch, allowing tracking to continue when your smartwatch is charging, resting, or simply not being worn. Wrist for daily wear. Arm for training. Your watch does not have to do everything. Your data just needs to stay connected.

Designed for training, recovery, and sleep, the compact form factor fits naturally into your routine, whether paired with an Amazfit smartwatch or worn alongside a traditional timepiece. By reducing data gaps and extending tracking beyond the wrist, Helio Strap Pro helps maintain a continuous view of heart rate, movement, recovery, and training readiness.

Your Workouts, Your Way

Support every part of your training through 50+ sports modes available within the Zepp App. Designed for strength, endurance, conditioning, and recovery, each mode helps capture the data needed to support every phase of training.

Charge Less. Train More.

Up to 11 days of battery life supports demanding schedules, travel, recovery tracking, and structured training without interruption.

Seamless Integration with Third-Party Platforms

Sync training data from the Zepp App to leading platforms like Strava, TrainingPeaks, Stryd, and more to keep workouts, recovery, and performance connected across the tools you already use.

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.
