The method
What is IHHT?
Intermittent hypoxia–hyperoxia training (IHHT) is controlled oxygen training that simulates an altitude stimulus – virtually without climbing a mountain.
Via a breathing mask, users alternate between oxygen-reduced and oxygen-enriched air. This stimulus supports the body’s adaptability and modern recovery and prevention concepts.

FAQ
Frequently asked questions about IHHT.
Answers to the most important questions on intermittent hypoxia–hyperoxia training and cellgym systems.
Intermittent hypoxia–hyperoxia training (IHHT) is a form of simulated altitude training where barometric pressure stays constant while the oxygen content of the breathing gas changes. Participants alternate between oxygen-reduced and oxygen-enriched air—similar to ascending and descending a mountain—and train the body to use oxygen efficiently, comparable to altitude training. IHHT uses dedicated hypoxia devices and masks such as cellgym®. For a safe, effective programme we recommend support from a qualified professional.
