Breath
The core. Apnea and CO2 tolerance training, plus breath gears you use inside your runs and races.
THE 4-WEEK VO2 MAX CHALLENGE · ENROLLMENT CLOSED
Most athletes build the engine. Almost no one teaches you how to use it effectively.
Want a higher VO2 max? This is the system most coaches never teach: breath, CO2 tolerance, and nervous-system control. Built for High Performers, on the start line and at work.
Enrollment is now closed.
The first cohort is officially ready to get started.
Works alongside the training you already do.

01 / The goal
Want a higher VO2 max? This is how.
You train hard. You've done the intervals, the threshold work and the long Zone 2 sessions. You've built the engine.
What almost no one teaches is how to use it: how to breathe at pace, how to handle CO2 as it builds, and how to switch your nervous system on to perform and off to recover.
That's what this challenge teaches, step by step, over four weeks, alongside the training you already do.
Engine
Aerobic capacity
Built by your training
Driver
Breath, CO2 tolerance, nervous system
What I teach you
Build the engine. Learn to drive it.
02 / The system
One system. Three pillars.
Nervous system
The on and off switch. Downregulation, deeper sleep and faster recovery, so you can keep training at your highest output.
Environment
The support. Heat training done properly, morning light, sleep, and the supplements actually worth your money.
Cardio is still the foundation. This system helps you get more from it.
03 / Why me
I've done this myself.
When I started HYROX, I was coming off a desk job and my VO2 max tested at 56. Within a year I was racing HYROX Elite 15. I've since tested at 86.8.
Training built my engine. Breathwork taught me how to use it. I've worked with experienced breathwork coaches, spent two months with Tony Robbins' team studying the breath, and built my own system from it.
Today I coach that system to elite athletes and founders. This challenge is the first time I'm teaching it to a group.
04 / Who it's for
Built for High Performers.
Endurance athletes and executives who train seriously, perform at a high level, and want the exact tools to improve their VO2 max.
[VIDEO 2 — WHO THIS IS FOR — PENDING FROM CHASE]
This is for you if
- You want a higher VO2 max and a clear system to get there
- You train seriously and want legitimate tools to improve your performance
- You're ready to learn the breath and nervous-system tools most coaches never teach
- You're a High Performer: on the start line, at work, or both
This isn't for you if
- You're brand new to training
- You want a shortcut that replaces the training
- You won't show up to the calls or do the weekly assessments
- You want someone else to do the work for you
This program is intended for adults who are able to participate safely in breath-hold and physical training. Review the safety information and consult a qualified medical professional if you are unsure whether this work is appropriate for you.
05 / The four weeks
One focus each week.
Start Here
Your baseline
What VO2 max is, the safety screen and your baseline test, so you have real numbers to beat.
Week 1
Apnea Training
Build CO2 tolerance with my moving breath-hold protocol, done safely and deliberately.
Week 2
Nervous System Regulation
Learn the geared breath and how to shift your state on command, in training and at work.
Week 3
Heat Training
Use heat the right way, alongside your training, to support your aerobic work.
Week 4
CO2 Tolerance and Zone 2
Bring the system together inside your aerobic training, then retest your numbers.
Lesson
Practice
Sunday assessment
Monday live call
Each new lesson unlocks right after Monday's call. You practice all week, submit your assessment by Sunday, and we go over it together on the next call.
MEMBER PORTAL
Everything lives in one member portal: your weekly lessons, the weekly assessment, live call details and recordings, and a private community forum for questions between calls.
Safety is part of the protocol.
Apnea and breath-hold work must be approached responsibly. Members must review the safety information before participating and follow all environmental and stop instructions.
06 / Results
He already had the engine. He learned to use it.
Joe, a pro hockey player, tested at 52 and asked me for tricks before his retest. There aren't any. He committed to the breath work instead, and retested at 68.7.
"I've been wearing my Whoop since 2019, and my resting heart rate was super low, never had been that low, and that was like after the first day of doing it."
Individual results vary. A single test-to-test change has many factors, and no specific result is promised.

- Follow the safety instructions before participating
- Have another person present for the first attempt whenever possible
- Use a safe, open, soft, ground-level environment
- Never perform the exercises in or near water
- Never perform them near stairs, ledges, traffic, hard obstacles, machinery, or while driving
