The Fastest I've Ever Been — Dr. Drew Denson
Dr. Drew Denson reports his fastest athletic performance after using LiveO2, demonstrating that even well-trained athletes have oxygen delivery bottlenecks that adaptive contrast can remove.

What LiveO2 Does for Athletic Performance
Dr. Drew Denson describes experiencing his fastest athletic performance after beginning LiveO2 use — a result that reflects what happens when an already well-trained body receives the oxygen delivery optimization that adaptive contrast provides. The gains aren’t about fitness in the traditional sense; they’re about removing the oxygen delivery bottleneck that limits performance even in conditioned athletes.
For physicians and health professionals who are also athletes, LiveO2 offers the additional value of direct personal experience with the mechanism they recommend to patients.
Performance is an oxygen delivery problem. The same training produces more output, faster recovery, and less fatigue when oxygen is optimized before, during, and after exercise.
Key Takeaways
“What we do is we change what you breathe while you exercise so that you get more of the respiratory effect — in less time, with less fatigue.”
— Mark Squibb, CEO & Inventor of LiveO2Common Questions
LiveO2 is an oxygen training system that changes what you breathe while you exercise. It uses Adaptive Contrast — switching between oxygen-rich and oxygen-reduced air — to dramatically increase oxygen delivery to your cells in about 15 minutes.
About 15 minutes. You exercise on a bike or treadmill while the system manages the oxygen and altitude contrast automatically. Most people feel the effects within their first session.
Adaptive Contrast is LiveO2’s core technology. It switches between high-oxygen and low-oxygen air during exercise. The low-oxygen phase opens your blood vessels. The high-oxygen phase floods them with saturated plasma. The result is dramatically more oxygen reaching your tissues. Full explanation here.
LiveO2 uses the same oxygen you breathe every day — just in higher concentrations, combined with controlled exercise. It is a non-invasive training system. Consult your healthcare provider if you have specific medical concerns.
Athletes, practitioners, biohackers, and everyday people. LiveO2 systems are used in clinics, gyms, training facilities, and homes across the country. See how one doctor discovered it.
