LEARN THE TECHNIQUE
START by going through the 10 TECHNIQUE LESSONS, including the HYPOXiX CO2 TOLERANCE TEST. Based on your experience and your results on from the test, you can take as many of the 15 TRUE BEGINNER classes as you would like before moving forward with the HYPOXiX content. Please refer to the below on how to start based on the results of your HYPOXiX CO2 TOLERANCE TEST.

The HYPOXiX CO₂ Tolerance Test
Measure how well your breathing system adapts to movement
Why This Test Is Different
Most breath-hold assessments, like the classic BOLT score, are done while completely still after a gentle exhale. The HYPOXiX CO₂ Tolerance Test takes this concept further—linking controlled breathing, a full engaged exhale, and gentle movement to see how efficiently your body manages carbon dioxide under realistic conditions.
In other words, instead of testing your breath in isolation, we test how your brain, lungs, and muscles perform together.
⸻
The Science in Simple Terms
• Carbon dioxide (CO₂) is not just a waste gas—it’s a critical signal that regulates breathing and blood flow.
• Higher CO₂ tolerance often means calmer breathing, improved focus, better endurance, and faster recovery.
• During movement, muscles naturally produce more CO₂, so the ability to tolerate mild CO₂ rise under motion reflects real-world performance and nervous-system adaptability.
The HYPOXiX test measures how long you can comfortably hold your breath after an eight-second controlled, ENGAGED EXHALE while maintaining gentle movement—usually an isometric or rhythmic action such as a slow split squat or step-through. You are welcome to try this on your own or follow along in the video.
⸻
How to Perform the HYPOXiX CO₂ Tolerance Test
1. Set-Up
• Stand tall or sit upright with posture engaged.
• Breathe nasally for a few quiet breaths to settle.
• Prepare for a gentle, rhythmic movement (e.g., slow alternating step, small squat, or isometric hold).
2. The Exhale
• Perform one 8-second controlled exhale through the mouth or nose, focusing on an engaged, forceful finish that fully empties the lungs without strain. Perform this in conjunction with body weight squats or an isometric position. Warm up with a few sets nasal breathing before beginning the test. Continue moving on the Breath Retention.
3. The Hold
• When the exhale ends, begin your movement and start the timer.
• Continue the gentle movement and hold your breath until you feel the first clear urge to breathe—not a maximum push.
• Stop the timer as soon as you sense that urge.
• Resume slow nasal breathing and rest for 60–90 seconds.
4. Repeat 3 Times
Take the median (middle) result of your three holds. This ensures a reliable score.
⸻
How to Interpret Your Result
RESULTS + INTERPRETATION
BEGINNER: < 4 seconds: Low CO₂ tolerance; body and nervous system are highly reactive to rising CO₂. Focus on slow exhale drills and short holds.
INTERMEDIATE: 4–8 seconds: Moderate tolerance; breathing control and recovery are improving. Progress to repeated gentle movement holds.
ADVANCED: > 8 seconds: High CO₂ tolerance; efficient oxygen use and calm nervous-system response under light movement. You can safely integrate longer holds.
These ranges are calibrated for movement-based testing, where hold times are naturally shorter than static BOLT tests due to muscular CO₂ production.
⸻
What Your Score Means
• Shorter holds → lower CO₂ buffering, more sensitivity to breathlessness or anxiety.
• Longer holds → stronger respiratory efficiency, better emotional regulation, and improved endurance.
• Progress → not measured by maximal holds, but by increasing comfort, steadiness, and recovery over weeks.
⸻
How to Use the Data in Training
• Use your test result to set your current HYPOXiX training level and this will guide you as to which classes to take.
• Re-test every 2–4 weeks under the same conditions.
• Track not only seconds, but also how calm you felt—comfort at 12 seconds can be more meaningful than strain at 20.
• Expect gradual improvement: +2–3 seconds every few weeks indicates strong adaptation.
⸻
Safety Notes
• Always perform the test in a safe, seated or standing position—never underwater or during intense exercise.
• Stop immediately if dizzy, light-headed, or uncomfortable.
• Individuals with cardiovascular, respiratory, or anxiety conditions should consult a professional before performing breath holds.

ZipUp Activation
The ZipUp Activation is your preparation for many of the exercises in the CORE and TOTAL BODY CORRECTIVE STRENGTH classes. This serves as a postural and deep core set up, so that you are reinforcing and optimizing good function of your breath and your body during exercise.
-
Engaged Inhale
The ENGAGED INHALE is STEP #2 of the Breathography Technique. In this step, you Inhale 2 Staccato sniffs of air through your nostrils with the ACTIVATIONS held from the ZipUp Activation.
-
Engaged Exhale
The ENGAGED EXHALE is the 8 Second Exhalation with FOUR Breath Stages:
1. Blow, 2 seconds
2. Hiss, 2 seconds
3. Soft Shh, 2 seconds
4. Loud Shh, 2 secondsThis happens on a Breath Crescendo and is the KEY to you getting a FULL exhale and strengthening your core!
