Amazfit Helio Strap Pro Solves Fitness Tracker Issue With Second Wearable

For Hyrox athletes, wrist-based heart rate monitors often fail during heavy lifts or rowing. Amazfit's new Helio Strap Pro tackles this with a radical fix: a second wearable sensor.

Amazfit, the wearable brand owned by Zepp Health, has launched the Helio Strap Pro — a screen-less fitness tracking system designed specifically for Hyrox fans and hybrid athletes. Announced in July 2026, the device consists of two separate sensor housings that can be worn on different parts of the body, allowing users to capture more accurate biometric data during high-intensity interval workouts, heavy weightlifting, and rowing — exercises where traditional wrist-based trackers often struggle.

Hyrox, the fitness competition that combines a 1km run with functional workout stations such as sled pushes, burpees, and kettlebell swings, has surged in popularity worldwide. But participants quickly discovered that standard fitness watches lose accuracy during dynamic movements or when the wrist flexes. The Amazfit Helio Strap Pro directly addresses this pain point by decoupling the sensor from the wrist — users can place one sensor on the bicep or chest and the other elsewhere, such as on the forearm or ankle, to pick up motion and heart rate data from multiple angles.

The system is entirely screen-less, relying on a companion app and pairing with existing Amazfit smartwatches or third-party devices. Each sensor housing is lightweight, waterproof to 5 ATM, and contains an optical heart rate sensor, accelerometer, gyroscope, and temperature sensor. Battery life is rated at 10 days per housing, and the dual-sensor arrays sync in real-time to compute metrics like heart rate variability (HRV), cadence, power output, and recovery time. Pricing is set at $199 for the starter kit, with availability beginning in August.

Industry analysts see this as a smart play for a niche but rapidly growing market. "Hyrox athletes are a demanding bunch — they can't afford inaccurate data during a race," said James Park, analyst at Wearable Research. "A second sensor isn't just a gimmick; it's a practical solution that could trickle down to general fitness trackers if it proves successful." The move also highlights a broader trend: wearable companies are moving away from the all-in-one smartwatch form factor toward modular systems that prioritize accuracy and comfort.

What's next? Amazfit has not announced plans for a consumer version, but early reviews from Hyrox influencers are expected in the coming weeks. If the Helio Strap Pro gains traction, other brands like Garmin or Whoop may explore similar multi-sensor designs. For now, the device offers a clear answer to one of fitness tracking's oldest headaches — and it comes in a box of two.
