The Best IHHT System: Intermittent Hypoxic Hyperoxic Training
The only altitude training system with hypoxic + hyperoxic switching during exercise. Patented. Coached. Proven.
The Missing Piece: Oxygen Recovery
Most hypoxic systems only take oxygen away. They never give it back. LiveO2 adds an oxygen recovery phase — concentrated oxygen at peak exercise. That’s what drives deep tissue healing that passive IHHT devices can’t match.
EWOT, IHT, IHHT, Adaptive Contrast
What’s the Difference?
Even experts mix these up. Here’s the simple version — and why it matters.
Why buy three things that each do part of the job? LiveO2 Adaptive Contrast is IHT + IHHT + EWOT — combined into one system. Done during your workout. In 15 minutes.
Ready for Your Unfair Advantage?
You don’t need fixing. You want the edge. Here’s what LiveO2 delivers.
Higher VO2 max
The #1 predictor of how long you’ll live.
More EPO
More red blood cells. More oxygen to every muscle.
Faster Recovery
Bounce back from hard sessions in hours, not days.
Sharper Focus
Flood your brain with oxygen at peak exertion.
Results in 15 Minutes
Not 8 hours in an altitude tent.
One System Replaces Three
A clinic, a tent, and a hypoxic generator — in one.
Why 15 Minutes on LiveO2
Beats 8 Hours in a Tent — or 40 Minutes Sitting Still
Active IHHT vs Stationary IHHT
Skip the Altitude Tent
Sleep is your #1 recovery tool. Sleeping at altitude is harder. Sleep quality drops.
You’re wrecking your best recovery window to get a stimulus you could get in 15 minutes. That’s backwards.
No other system combines all three: altitude simulation + exercise + oxygen recovery. Standalone generators give you altitude only. Tents give you altitude while you sleep. Stationary IHHT does both phases — but you’re just sitting there. LiveO2 gives you everything — during your workout. And a real human coach who’s invested in your results.

“This is legal blood doping.”
How Adaptive Contrast® Works
Traditional IHHT makes you sit still. LiveO2 does it while you exercise — so oxygen reaches deeper than any passive device.
Oxygen Recovery Flood
Concentrated oxygen floods starving tissue. This is the recovery phase most systems skip.
Oxygen at Peak Exercise
At peak exertion, flip back to concentrated oxygen. It floods through wide-open vessels with 3× pulse pressure. [5]
Altitude Switch
Switch to reduced oxygen. Simulates altitude up to 22,000 ft. Your body triggers survival adaptations.
Vessels Open Wide
Blood vessels dilate maximally. EPO surges. Your body prepares for the oxygen flood.

FAQ
IHHT stands for intermittent hypoxic hyperoxic training. It switches between low-oxygen and high-oxygen air. Regular IHHT machines do this while you sit still. LiveO2 does it while you exercise — so oxygen reaches deeper and works faster.
You breathe low-oxygen air for a few minutes. Your blood vessels open wide and EPO production jumps. Then you switch to concentrated oxygen during exercise. It floods through those wide-open vessels into deep tissue.
An altitude tent makes you sleep in a hot, sealed bag for 8+ hours. You get altitude — but no oxygen recovery and no exercise. LiveO2 gives you the same altitude stimulus plus oxygen recovery in 15 minutes. Then you sleep in your real bed.
Yes. LiveO2 was built for home use — IHHT at home on your own schedule. Connect it to any bike, treadmill, or rower. Setup takes 30 minutes. No clinic visits, no appointments, no per-session fees.
15 minutes. That’s the whole session — not a warm-up. Exercise makes the altitude-to-oxygen contrast so strong that 15 minutes beats 40 minutes on a passive IHHT device or 8 hours in a tent.
Hypoxico, CellGym, and MITOVIT are passive devices. You sit or lie down. LiveO2 does IHHT during exercise — the oxygen reaches deeper because your heart rate and blood flow are elevated. And LiveO2 includes 1-on-1 expert coaching. They ship you a box.
Most people feel the difference after their first session — more energy, sharper focus. Over weeks, expect better endurance and faster recovery. Research shows ~20% VO2 max improvement and 49% more EPO production. Call for a free consult to discuss your goals.
LiveO2 Adaptive Contrast. It’s a complete altitude generator and training system — altitude simulation, oxygen recovery, AND exercise all in one. The Extreme model goes up to 22,000 ft with guided protocols and expert coaching. Clinical-grade home IHHT since 2011.
