The Cloud is the active center of The Current Method. You ride a stationary bike and breathe through a mask connected to our Contrast Oxygen system. During a typical session, the air switches repeatedly between a high altitude simulation of approximately 8 to 14% oxygen and oxygen rich air of approximately 70 to 80% oxygen. A 25 minute session may include more than 30 transitions.

You set the physical intensity. Ride gently and focus on breathing and managing the contrast, or pedal hard for a demanding cardiovascular workout. The aim is to notice how you respond to challenge and how efficiently you recover.

We describe the low oxygen intervals as going up the mountain. Oxygen availability falls below the 20.9% in normal air, and your breathing, heart rate and circulation respond. At the switch, you breathe oxygen rich air, keep pedaling and deliberately bring your effort and breathing back under control. Then you climb again.

The repeated contrast is what distinguishes The Cloud from simply exercising in an altitude room. It creates a pump-like rhythm of cardiovascular response and recovery. That is an analogy for adaptation, not a literal pumping of blood or toxins.

VO₂ max measures the greatest rate at which your body can take in, transport and use oxygen during hard exercise. It reflects the lungs, heart, blood vessels and working muscles together. Intermittent hypoxic training has shown potential to improve aerobic capacity in some studies, though findings vary by protocol and it has not consistently outperformed comparable exercise in normal air.

That is why we call this oxygen training. The bike provides movement; the changing air adds a distinct oxygen challenge.

As the climb becomes uncomfortable, a coach helps you remain aware of your breathing and effort. When the oxygen rich interval begins, you practice slowing down and recovering. Challenge → awareness → control → recovery. This is our way of doing hard things mindfully.

Altitude training: Controlled periods of reduced oxygen echo one aspect of training at elevation.

Oxygen rich recovery: Each climb is followed by air with a much higher oxygen concentration.

Cardiovascular training: Your chosen pace can make the ride gentle or intense.

Breathwork and mindfulness: You practice attention and deliberate breathing through both challenge and recovery.

The Cloud layers these practices into one coached experience. It is a non-pressurized approach to oxygen training. Unlike hyperbaric oxygen therapy, it does not use increased atmospheric pressure, and the two should not be assumed to have equivalent effects.

Intermittent hypoxic and hypoxic-hyperoxic approaches are being studied for aerobic capacity, exercise tolerance, vascular function and metabolic health. Results depend on the individual and protocol. Some people feel energized, tired or briefly off after an unfamiliar session, so we build intensity gradually and make recovery central. There is no established basis to promise detoxification from this session.
