Garmin has acquired Moxy Monitor, a company known for producing wearable sensors that track muscle oxygen saturation during exercise. The move suggests the company may integrate this physiological data into future consumer wearable products.
Why it matters
This acquisition signals a potential shift in how fitness trackers monitor exercise intensity and recovery by incorporating direct measurements of muscle tissue health. It expands the metrics available to athletes aiming to optimize their training regimens through objective data.
Garmin confirmed the acquisition of Moxy Monitor on September 29, 2026, following the company's prior trademark application for a feature called Muscle Battery. The transaction details were not publicly disclosed as the deal fell below SEC reporting thresholds.
The players
Garmin
A manufacturer of GPS-enabled navigation and wearable fitness tracking technology for athletes and outdoor enthusiasts.
Moxy Monitor
A developer of wearable near-infrared spectroscopy sensors designed to measure real-time muscle oxygen saturation.
The details
The Moxy Monitor device utilizes near-infrared spectroscopy to measure levels of oxygenated hemoglobin and myoglobin directly within active muscle tissue. By tracking these oxygen levels, the technology provides a real-time window into how muscles respond to physical exertion. Once paired with sports computers or training platforms, this data allows users to identify specific fatigue thresholds during high-intensity activity.
Timeline
Garmin filed a trademark application for Muscle Battery in 2026.
Garmin confirmed the acquisition of Moxy Monitor on 2026-09-29.
Health Landscape
This move reflects the ongoing trend of moving clinical-grade physiological metrics, such as near-infrared muscle oxygen tracking, into the consumer wearable market. It follows the industry-wide push to transition from simple activity logging toward comprehensive, biomarker-based performance monitoring.
Athletes who monitor their training loads should keep an eye on future Garmin updates regarding the Muscle Battery algorithm, as these tools may provide new ways to track recovery. If you currently use wearable tech to manage exercise intensity, discuss with your doctor how muscle-fatigue metrics can best support your specific fitness goals.
The takeaway
The acquisition of Moxy Monitor technology positions Garmin to bring advanced muscle-oxygen data to broader consumer audiences. Readers should monitor future device updates for features that quantify muscle fatigue through oxygen saturation levels rather than heart rate alone.
