In a world where step counts and heart rate zones have become the default fitness language, one company is taking a bold step forward by measuring what truly matters. NNOXX, a human performance technology company, is turning the industry on its head by introducing a new biological standard: real-time muscle oxygenation and nitric oxide. Their breakthrough wearable fitness device doesn’t simply track movement; it reveals what’s happening inside your body as you train.
The Measurement Blind Spot
Despite the explosion of fitness trackers and wearables, most still fall short in one critical area: they don’t directly measure how exercise affects the body. Metrics like VO2 max estimates and heart rate rely on broad population algorithms, often missing the mark on individual performance. This gap frustrates athletes, coaches, clinicians, and fitness enthusiasts alike.
NNOXX addresses this blind spot with a proprietary muscle oxygen sensor and the first nitric oxide wearable of its kind. These tools provide an unfiltered look at what is happening in real time inside the muscle tissue where performance and recovery take shape.
A New Kind of Data, A New Kind of Impact
At the core of NNOXX’s system is a novel, patent-pending optical model. Unlike traditional photoplethysmography, this next-generation fitness wearable dives deeper, measuring desaturation of hemoglobin and the body’s nitric oxide-driven vasodilation process. These are key physiological markers of oxygen delivery, vascular response, and cellular adaptation.
By capturing this information, NNOXX delivers personalized insights through its Performance Readiness Score, a metric that reveals how well the body responds to training or recovering between sessions. Integrated with platforms like Strava, Garmin, and Peloton, this fitness performance technology becomes part of an ecosystem that translates raw biological data into real-world performance gains.
The Team Behind the Tech
The company’s leadership reflects its blend of scientific rigor and business acumen. Justin Saul, CEO and Co-Founder, brings a background in software engineering and a strong track record in tech entrepreneurship. His vision bridges complex innovation with market strategy, positioning NNOXX as a standout in the performance monitoring space.
Evan Peikon, Chief Physiologist and Co-Founder, is a leading bioscientist and data expert. With roots in elite athletics and military performance, Evan leads the development of NNOXX’s bio-algorithms.
Supporting them are David Thompson, VP of Sales and Marketing, and Jennifer Corso, VP of Clinical and Regulatory Affairs, key figures in driving adoption across elite sport, clinical rehab, and emerging consumer segments.
Why It Matters Now
The global health and fitness tech market has surpassed $100 billion, yet most wearables still rely on surface-level metrics. NNOXX is creating a new approach where real-time SmO₂ monitoring and nitric oxide data are not science fiction but actionable insights. From Olympic athletes and the Fount Cycling Guild to biohackers and physical therapists, users can finally access highly individualized, biologically grounded feedback.
Whether looking for the best wearable for athletes or tools to improve training efficiency, NNOXX offers a new standard in human performance monitoring. This is not simply another fitness tracker; it is a smarter way to understand the effects of exercise.
