Amazfit Helio Strap Pro Solves Fitness Tracker Issue With Second Wearable

The Two-Sensor Setup

Forget the wrist. The Helio Strap Pro system splits tracking across an upper-arm unit — the Core Motion HR — and a waist-worn motion sensor. Amazfit calls it a "multi-position movement system," marketing-speak for something straightforward: one sensor owns the trunk, the other captures limb movement. Together, the system separates general body movement from extremity movement instead of smearing both into one wrist signal.

The real application is Hyrox. Amazfit partnered with the competition in 2024, and the system is built to disambiguate the event's mixed disciplines — SkiErg, rowing, sled push, and others — so you can see how you performed across each in the Zepp app after a tracked session.

Over 60 tracking modes ship with it, including running and HIIT. The catch: you'll likely need to start sessions manually in the Zepp app so auto-recognition doesn't guess the workout type wrong.

What this isn't: a trail runner's dream. Forbes notes the system isn't optimized for pace-and-distance athletes. But if your week blends trail miles with sled pushes, loaded carries, and functional circuits, the separation of effort from movement could surface patterns a wrist-only tracker buries.

The Practical Math

Here's where it gets interesting for anyone sick of subscription creep. The full kit runs $199.99 — both sensors, both bands, no monthly fee. Compare that to Whoop at $25 a month and the math flips fast for anyone training on a budget.

Battery life holds. The arm unit runs up to 11 days; the waist sensor stretches to 40 days. Both carry 5ATM water resistance, so sweat and rain aren't a problem.

Read the fine print, though. At launch, you need an Amazfit Balance 3 or Balance Ultra smartwatch to unlock the full Hyrox Race and Simulation modes. Amazfit says that requirement won't be permanent, but right now it's the cost of entry for the complete system.

What It Means For Your Training

If your week looks like trail runs punctuated by grind sessions — sled work, loaded carries, mixed-modal intervals — the Helio Strap Pro addresses a real gap. Wrist trackers smear everything into steps and heart rate. Splitting the signal across two positions means you can finally see whether your legs are loaded during upper-body efforts, or whether your "intense" circuit is just your arms going through the motions while your core coasts.

Scott Shepley, Amazfit's head of marketing, frames it as "a more complete understanding of how effort, movement and performance change across a demanding workout." Translation: more data points to manage training load instead of guessing at intensity.

For pure trail runners, this isn't your tool yet. For hybrid athletes building strength-endurance alongside their miles, it's the first screen-free system designed to keep up with what you're actually doing.
