Why Mark Squibb Started LiveO2
Mark Squibb founded LiveO2 after a personal health crisis led him to discover that combining controlled hypoxia with high-oxygen exercise produced results in a completely different category from anything else he'd tried.

Real People. Real Results.
LiveO2 founder Mark Squibb didn’t start from a business idea — he started from a personal health crisis that conventional medicine couldn’t resolve. His own investigation into oxygen delivery led him to discover that combining high-oxygen breathing with exercise was dramatically effective, and that adding the hypoxic component elevated outcomes into an entirely different category.
That discovery became the foundation of LiveO2’s Adaptive Contrast System — and after years of development and tens of thousands of users worldwide, the results continue to be the motivating force behind the company.
15 minutes. Real results. Adaptive contrast delivers more oxygen to more tissue in a single session than passive oxygen therapy can in an hour. That’s physics, not marketing.
Key Takeaways
- LiveO2 began as a personal solution to a health problem medicine couldn’t fix
- The hypoxic component was the discovery that changed everything
- The system is built around existing biological mechanisms — not new ones
- Tens of thousands of users worldwide have validated the approach
“LiveO2 changes what you breathe while you exercise. That one change produces outsized results in a fraction of the time.”
— 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.
