Welcome to AltitudeO2
AltitudeO2 uses the hypoxic component of adaptive contrast to simulate altitude training conditions, producing real VO2 max and endurance gains without leaving sea level.

What LiveO2 Does for Athletic Performance
AltitudeO2 is a LiveO2 protocol designed for endurance athletes and altitude competitors who want the physiological adaptations of high-altitude training without the logistics of actually living at elevation. By using the hypoxic component of adaptive contrast, the protocol simulates altitude conditions during exercise — triggering the same biological responses.
Those responses include increased red blood cell production, improved oxygen efficiency, and meaningful gains in VO2 max. Athletes gain altitude-level conditioning on their own schedule, without relocating or compromising their existing training environment.
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
- Simulates altitude training stimulus using controlled hypoxia during exercise
- Triggers increased red blood cell production and improved oxygen efficiency
- VO2 max improvements comparable to actual altitude exposure
- Accessible from any training environment — no altitude required
“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.
