Question 1

What is the price of the Amazfit Helio Strap Pro?

Accepted Answer

$199.99 in the US. The original Helio Strap was $99.99 and is currently out of stock.

Question 2

Does the Helio Strap Pro require a subscription?

Accepted Answer

No subscription is required for any feature, including HybridCharge, LifeLoad, HYROX modes, and all health tracking.

Question 3

Which watches are compatible with the Helio Strap Pro?

Accepted Answer

Balance 3 and Balance Ultra at launch. The full three-device system, watch plus arm sensor plus waist sensor, requires one of these two watches. Support for additional Amazfit watches has been confirmed, with no timeline given.

Question 4

Does the waist sensor work for general gym training?

Accepted Answer

Not at launch. The Helio Core Motion waist sensor is currently limited to HYROX Race and HYROX Simulation modes. Outside those modes, it is completely inactive. Broader workout support is confirmed to be coming, with no timeline.

Question 5

What is the battery life of the Helio Strap Pro?

Accepted Answer

The Helio Core Motion HR arm sensor lasts up to 11 days on a single charge. The Helio Core Motion waist sensor lasts up to 44 days, which reflects its limited active use outside HYROX sessions.

Question 6

Is the Helio Strap Pro worth upgrading to from the original Helio Strap?

Accepted Answer

For HYROX athletes, yes. The waist module delivers per-station muscular load analysis that justifies the price difference. For general gym and hybrid athletes, the case is weak until Amazfit extends support for waist sensors to broader workout modes.

Question 7

What sensors does the Helio Strap Pro add over the original?

Accepted Answer

The wrist module gains a geomagnetic sensor, making it a 9-axis IMU compared to the 6-axis IMU in Gen 1, and a skin temperature sensor. LifeLoad is also new. The Helio Core Motion waist sensor is entirely new to the Pro system.

Question 8

Can the Helio Strap Pro broadcast heart rate to other devices?

Accepted Answer

Yes. It broadcasts real-time heart rate via Bluetooth to compatible Amazfit watches, cycling computers, fitness equipment, and supported training apps, including treadmills.

Question 9

What third-party apps does the Helio Strap Pro sync with?

Accepted Answer

Strava, TrainingPeaks, Runna, adidas Running, komoot, Relive, Apple Health, and Google Fit.

Question 10

Does the Helio Strap Pro work without an Amazfit watch?

Accepted Answer

The Helio Core Motion HR arm sensor works independently to track health, sleep, and HybridCharge, and supports 50+ workout modes without a watch. The waist sensor requires a Balance 3 or Balance Ultra to function at all.

Question 11

What is the difference between Helio Core Motion HR and Helio Core Motion?

Accepted Answer

The Helio Core Motion HR is an arm- or wrist-worn sensor with optical heart rate monitoring, a 9-axis IMU, skin temperature, and 50+ workout modes. The Helio Core Motion is the waist-worn module with a 9-axis IMU only, active exclusively in HYROX Race and HYROX Simulation modes, with a 44-day battery life.

Question 12

Does the Helio Strap Pro waist sensor have a heart rate sensor?

Accepted Answer

The waist module contains BioTracker 6.0 PPG hardware, but it is not used for health tracking or active outside HYROX modes at launch.
