CO2 TACTICS
Your Skills Are Trained. Your Stress Capacity Isn't.

Built For
Pressure.

Big moments reveal an athlete's capacity. The second pressure enters, a chain takes over — body, thought, story, action — and most training enters that chain too late. We build stress capacity at the source, measure it daily, and everything you've trained finally shows up.

The Chain

Five Things Happen
in Every Pressure Moment.

Pressure doesn't break your skills.
It cuts off access to them.

Same chain, every athlete, every sport. The only question is where training enters it.

01
The Trigger

The 3-2 count. The free throw. The penalty kick. Fourth and one. Match point. The starting gun. The coach's voice.

Not trainable — your trigger is your trigger
CO₂ Tactics Trains 02–05
02
The Body Responds

Heart spikes. Breathing goes shallow. Palms sweat.

We Start Here
03
A Thought Fires

"Don't blow this." The mind follows the body's lead.

04
A Narrative Attaches

"I always choke." Identity gets written in the moment.

Where most mental training starts
05
Behavior Shows Up

Mechanics tighten — or hold. The moment is decided.

We train 2 through 5. We start at 2 — so 3, 4, and 5 can work.

The Core Insight

Most mental training enters the chain at step 4 — asking an athlete to rewrite the narrative while the body is still in alarm. By then, the body has already voted. We enter at step 2: train the body to hold, and the thought, the narrative, and the mechanics finally have a chance.

The Method

A Measurable System

Three steps. Two capacities — physical and mental. One outcome: skill that holds under pressure.

01
MEASURE
Physical · Mental

Two simple breath tests — BOLT and MBT — put a number on how much pressure your body can take before it panics. That number is your baseline. You cannot improve what you cannot measure.

02
TRAIN
Physical · Mental

Breathing protocols raise your stress ceiling. Focus and composure drills build the habits that hold under pressure. And as the number climbs, the deeper work — confidence, identity, resilience — finally sticks.

03
PERFORM
Physical · Mental

Composure holds. Decisions stay sharp. Skills remain accessible. The athlete who shows up in practice shows up when it counts.

The Science

Two Bodies of Research.
One System.

CO₂ tolerance has been studied for decades in respiratory psychophysiology: how sensitive the body is to rising CO₂ predicts how early its alarm fires — fast breathing, racing heart, narrowed attention. That sensitivity is trainable, and it's what BOLT and MBT measure.

Challenge-and-threat research in performance psychology shows the state the body is in when pressure arrives shapes whether the moment registers as a challenge or a threat — and which one it registers as predicts performance.

One explains the body. The other explains the moment. We train the first so the second breaks your way.

Common Questions

Questions. Answered.

What athletes, parents, coaches, and directors ask us before they start.

EveryoneWhat exactly is stress capacity — and why does it matter?

Stress capacity is how much pressure your system can absorb before it flips into survival mode — fast, shallow breathing, a racing heart, narrowed thinking. When that happens, your trained skill is still in there. You just can't get to it. We measure that capacity with two simple breath tests (BOLT and MBT), give you a number, and train the number up so you keep access to your skill when the moment is biggest.

EveryoneIs this a breathing app or a mental performance program?

Neither — it's the foundation under both. Breathing apps train a technique. Mental performance trains a mindset. But mindset work only lands in a body calm enough to receive it — and under pressure, an untrained body isn't. We train stress capacity: how much pressure your body can handle before it flips into survival mode. It has a baseline, it has a number, and it moves when you train it. Build that first, and everything else — confidence, routines, focus — finally has somewhere to stand. And yes, we train that side too: the mental skills are built into the system, in the order they land.

AthletesWhat does the daily work actually look like?

Wake up, run your morning test, log the number, then complete a short prescribed session. Call it about ten minutes. The app tells you exactly what to do each day — no guessing, no equipment, no extra gear. Consistency beats volume here. Show up daily and your score moves.

AthletesHow fast will I see results?

You'll see it in the numbers first. Your breath-test scores and your Pressure Capacity Score trend in the app, so you're never guessing whether it's working. Stay consistent and the trend moves within the first few weeks. Then you start noticing it where it counts — the reset you can actually pull off when the game is on the line.

AthletesDoes this work for my sport?

Pressure doesn't care what sport you play. A 3-2 count, a free throw, a penalty kick, a start line, a match point — the physiology underneath is the same, and so is the fix. The founders come from baseball, but the system trains the engine every athlete runs on.

ParentsIs this safe for a younger athlete?

Yes. Every protocol is scaled to your athlete's own test scores, not a fixed standard, and the app has built-in guardrails before any session starts. Training begins at 14. If your athlete is younger, reach out to us directly at info@co2tactics.com and we'll talk it through with you.

ParentsMy athlete is under 18. How does signup work?

Built for it. When an athlete under 18 signs up, we collect a parent or guardian's name and email first. You're in the loop from day one. With Private, your athlete also gets a monthly 1-on-1 session with James or Matt to work the concepts — and you get a direct line between calls.

ParentsWhat does it cost, and can we cancel?

The System is $99/month after a free 7-day trial, or $999 for the year. Private is $399/month per athlete ($599 for two) and adds a monthly 1-on-1 session where a founder works the concepts with your athlete. Both cancel anytime. The Flagship is built for teams and organizations and scoped per roster — request a slot and we'll build it with you.

CoachesHow does this fit into a season we've already planned?

It sits underneath everything you already do. Ten minutes a day, on the athlete's own time, with no practice time lost. On the Flagship, your staff gets the coach console so you can see who's testing, who's trending, and who's drifting — before it shows up on the field.

CoachesCan I see my athletes' data?

On the Flagship, yes — the whole roster on one console, every athlete's trend line in front of you. Individual System members own their own data. Private athletes review their trends live in their monthly session with a founder.

DirectorsWhat does a program-wide rollout look like?

We onboard your full roster, put your staff on the coach console, and send you a weekly director report with the roster table. You get monthly staff calls, a direct line to James and Matt, and in-person visits — the founders in your building, running the system with your athletes. Request a slot and we'll build the plan around your calendar.

DirectorsHow do we measure the return on this?

That's the point of the whole system. Every athlete carries a number. The weekly report shows you who's building capacity and who isn't, roster-wide, in one table. You get to put a trend line next to your season — not a feeling.

EveryoneWhere do I start?

Take the free assessment and get your baseline. If you're an athlete, start the 7-day trial. If you're a parent, book the Private intro call. If you run a roster, request a Flagship slot. One method, three doors — pick yours.
