▶ Build Muscle Size, Increase Strength & Improve Recovery | Huberman Lab Essentials 19:54 “The other one that's really terrific and the Andy Galpin's group is using, and I'm delighted about this because it relates to something that my lab is very excited about as well, is carbon dioxide tolerance.” ▷ How to Improve Your Mobility, Posture & Flexibility | Dr. Kelly Starrett 2:54:38 “Just like my CO2 tolerance, my breath holds are very short when I'm stressed and under-recovered.” ▷ How to Breathe Correctly for Optimal Health, Mood, Learning & Performance 1:10:21 “The carbon dioxide tolerance test is a sort of back of the envelope measure of how well you are managing carbon dioxide. That is how well you can control your breathing at both the mechanical and the chemical level.” ▷ Dr. Andy Galpin: Maximize Recovery to Achieve Fitness & Performance Goals | Huberman Lab 2:44:42 “if you don't have a device like that you could also use honestly the CO2 tolerance test... and that has actually been in our coaching experience... this tends to track extremely closely with HRV and other metrics of recovery.” ▷ Dr. Andy Galpin: How to Build Physical Endurance & Lose Fat | Huberman Lab Guest Series 2:56:50 “"So the interesting test here is your CO2 tolerance... On Brian's website, you can go directly there... But the CO2 tolerance test is a test of exactly what you just mentioned."” ▷ LIVE EVENT Q&A: Dr. Andrew Huberman Question & Answer in New York, NY 40:38 “"There is one tool that's used in the freediving community and in other communities that you can use as a kind of thermometer of how well you're functioning... It's this carbon dioxide tolerance test."” ▷ How to Build Endurance in Your Brain & Body 1:24:05 “a great way to do that is to apply the carbon dioxide tolerance test, which is four breaths in and out, inhale, exhale, inhale, exhale, inhale, exhale, inhale, exhale, then a big inhale, and then a slow controlled exhale. If that slow controlled exhale is 60 seconds or longer, it means that you're parasympathetic, your calming nervous system is under your control, and you're ready to go.” ▷ Science of Muscle Growth, Increasing Strength & Muscular Recovery 1:27:21 “Here's how you do the carbon dioxide tolerance test... You're going to repeat that four times... Then hit the timer. And your goal is to release that air as slowly as possible through your mouth... If your carbon dioxide discard time is 20 or 25 seconds or less, you are not necessarily recovered... If your carbon dioxide discard time is somewhere between about 30 seconds and 60 seconds, you are in what we would call kind of the green zone.”
