When it comes to fitness tech, Suunto might not be the first name you think of – brands likeGarminhave long dominated the conversation. But Suunto’s new feature, called ZoneSense, could giveGarmin watchesa run for its money. So what is ZoneSense, and why does it matter for your training? Let’s dive in.
The core of the technology lies in how it measures the stress on your heart. Unlike Garmin, which focuses on heart rate zones or power, Suunto’s ZoneSense taps into heart rate variability.
It tracks the small fluctuations between heartbeats, which are mapped against different metabolic states, meaning it can tell you when your body shifts from burning fat (aerobic) to working harder with less oxygen (anaerobic), or even when you’re pushing yourself to your absolute limits (VO2 max).
Traditionally, figuring out your aerobic and anaerobic thresholds meant stepping into a lab, wearing a mask, or even giving a blood sample to test lactate levels. With ZoneSense, Suunto has essentially miniaturised and simplified that process into a wearable feature on their latestmultisport watches. It’s as simple as pairing yourSuunto watchwith a heart rate belt and heading out for your workout.
The brand says this system works seamlessly across a range of sports, from cycling to running and even open-water swimming. Better still, ZoneSense is said to adapt to your body’s daily changes, accounting for factors like fatigue, heat, and altitude.
One thing to note is that ZoneSense requires aheart rate monitorfor accuracy, as wrist-based optical heart rate monitors can’t measure HRV accurately during exercise. While this might feel like a step back for some, especially given how convenient wrist-based monitoring has become, the belt is essential for the depth of data ZoneSense provides.

If you’re thinking this sounds a little too advanced, don’t worry – Suunto has made it user-friendly. The Suunto app displays your workout intensity with a simple color system. Green indicates aerobic effort, yellow signals you’re in the anaerobic zone, and red means you’re pushing your body to VO2 max levels. This visual feedback is immediate and easy to interpret during a session, helping you adjust your effort on the go.
ZoneSense works best during longer intervals or steady efforts, where the body has enough time to reach a consistent state. It’s perfect for longer runs, bike rides, or even Ironman training but not ideal for sports that require explosive, quick bursts of energy, like football or basketball.
Suunto’s partnership with MoniCardi, a Finnish medical tech company, is a big reason for ZoneSense’s scientific accuracy. MoniCardi developed the advanced time-series analysis behind ZoneSense, and it’s the first time this level of tech has been available in a wearable device. Suunto is positioning itself as a pioneer in this space, and this technology could give even Garmin’s top-tier features some serious competition.
Could this be the feature that makes Suunto the new go-to brand for serious fitness enthusiasts? Only time will tell. VisitSuuntoto find out more about the technology.
