Higher Inspired Oxygen
Breathing oxygen-enriched air raises inspired oxygen partial pressure. The effect on blood and tissue oxygen availability depends on concentration, workload and individual physiology.

PerformMore oxygen. While you work.
EWOT combines oxygen-enriched breathing with guided exercise to support a higher-quality conditioning session.
The oxygen may change what you can accomplish during the session. The exercise provides the training stimulus. We measure, program and retest rather than promise an outcome in advance.

What It Is
Exercise with oxygen-enriched air.
During EWOT, you wear a mask connected to an oxygen supply while exercising on a bike or another compatible platform. The oxygen concentration and workload are controlled, and the effort is scaled to your current capacity.
Room air contains approximately 21% oxygen. EWOT increases the inspired oxygen fraction during exertion. This is different from simply using a nasal cannula at rest—and fundamentally different from hyperbaric oxygen, which combines oxygen with increased atmospheric pressure.
EWOT is an exercise modality, not prescribed home oxygen therapy. It does not replace pulmonary, cardiac or medical evaluation when those are indicated.
How It Works
Change the environment. Preserve the work.
02
Active Exercise
You still pedal, produce force and elevate cardiovascular demand. Oxygen does not replace the work; it changes the conditions under which that work is performed.
03
Individualized Workload
Intensity is selected from your baseline, exercise history and goals. Progress comes from adjusting the training dose—not simply increasing oxygen.
The practical distinction: acute hyperoxia may allow more work or less breathlessness at a given workload, but that does not guarantee superior long-term adaptation.
Why It Belongs in Perform
Use oxygen to support the session—not define the outcome.
Perform is where we build aerobic capacity, work tolerance and repeatable output. EWOT belongs here because oxygen is paired with active training and the dose can be integrated into a larger conditioning plan.
Aerobic conditioning
Exercise-tolerance support
Higher-quality interval work
Reduced breathlessness for some users
Measured progression
Strategic conditioning within a Circuit
What the Evidence SaysBetter Established Still Uncertain
Acute performance and training adaptation are different questions.
During the Session
Controlled studies and reviews report that normobaric hyperoxia can improve acute exercise performance in some settings. Depending on the protocol and population, people may sustain more work, reach a higher output or experience less breathlessness.
After Weeks of Training
It remains unclear whether repeated training with supplemental oxygen consistently produces greater long-term improvement than equivalent training in room air. Evidence for a superior VO₂ max response is not settled.
Our position: EWOT may help create a productive training session. We do not promise a specific percentage improvement, a guaranteed VO₂ max increase or outcomes drawn from a different oxygen concentration or patient population.

What to expect.
Screen + Establish the Goal
We review relevant health considerations, exercise history and baseline capacity before choosing the training format and starting workload.
Breathe + Work
You exercise while breathing oxygen-enriched air through a mask. Workload and symptoms are monitored, and the session is adjusted when needed.
Recover + Progress
We assess your response and use it to guide future duration, intensity, frequency and placement within your Performance Circuit.
How It FitsStep One Step Two Step Three
Measure. Match. Re-measure.
Measure Capacity
When appropriate, VO₂ max and related testing establish a baseline and help identify the intensities that matter for your goal.
Match the Session
EWOT is selected when oxygen-enriched exercise adds a useful training option—not automatically because oxygen sounds advanced.
Re-measure the Result
We reassess at a defined interval so progression is based on your response rather than a predicted benefit.

Research with the limits left intact.
Hypoxia, Hyperoxia and Exercise Performance
This review found that oxygen-enriched air can improve exercise performance acutely in healthy adults and certain clinical populations. Results depend heavily on protocol, oxygen concentration and population.
Read on PubMed →Hyperoxic Training and Human Performance
The review describes the potential to complete more work while breathing elevated oxygen, while emphasizing that superior long-term performance adaptation in normal air remains uncertain.
Read the review →Repeated-Sprint Ability
In trained athletes, breathing a 40% oxygen mixture increased total work during a repeated-sprint protocol. That finding is protocol-specific and should not be converted into a universal EWOT outcome.

Screening matters. EWOT involves supplemental oxygen and physical exertion. Certain respiratory, cardiovascular, oxygen-sensitivity, pregnancy-related and other considerations may affect eligibility. Oxygen also increases combustion risk, so equipment and the surrounding environment must follow facility safety procedures.
FAQ
Questions answered.
How is EWOT different from hyperbaric oxygen?
EWOT increases the oxygen fraction you breathe while exercising at normal atmospheric pressure. Hyperbaric oxygen combines oxygen with increased chamber pressure, usually while you rest. They are different modalities with different mechanisms and safety requirements.
Do I need to be highly fit?
No. The workload can be scaled, but you must be able to participate safely in the selected exercise. Screening determines whether EWOT and the proposed intensity are appropriate.
Will EWOT increase my VO₂ max?
It may be incorporated into a plan designed to improve aerobic capacity, but a specific VO₂ max increase cannot be promised. Long-term hyperoxic-training evidence is mixed, which is why we establish a baseline and retest.
Will the oxygen make exercise easy?
No. You are still exercising. Some people may experience less breathlessness or tolerate more work under hyperoxic conditions, but the response varies with the workload, oxygen concentration and individual physiology.
Is EWOT the same as prescribed oxygen therapy?
No. EWOT is a supervised exercise and wellness service. It does not replace oxygen prescribed for a medical condition or evaluation by an appropriate clinician.
Can EWOT be combined with other services?
Yes, when the sequence supports your goal. It may be programmed with testing, Vasper or selected recovery services while accounting for the total workload of the session and week.
