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

Grit. Measure It.
Train It.
Built For Pressure.

Grit isn't a personality trait — it's a capacity. Physical and mental. We measure it, we train it, and we build athletes who can access their skills when pressure is highest.

The Problem

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

When stress rises, CO₂ tolerance is overwhelmed. Breathing becomes fast and shallow. The nervous system shifts into survival mode.

In that state, the athlete disappears — replaced by a physiological reaction that has never been trained.

Here's what most people miss: grit isn't just mental — it's physical, and it's trainable. We measure it. We train it. The result: athletes built for pressure.

Athletes Built For Pressure
The Method

A Measurable System

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

01
MEASURE
Physical · Mental

BOLT and MBT tests give you a precise baseline. Daily compliance and consistency turn it into a habit. 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. Two capacities. One system.

Tap to learn more ↓
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 Framework

Two Paths.
One Choice.

What determines the outcome is whether the body has been trained to handle pressure.

Without Stress Capacity Training
PRESSURE RISES
A high-stakes moment arrives. The body responds before the mind does.
STRESS RESPONSE ACTIVATES
CO₂ accumulates. Breathing becomes fast. Heart rate spikes.
NERVOUS SYSTEM OVERWHELMED
Fight-or-flight floods the system. Thinking narrows.
LOSS OF SKILL ACCESS
Trained skill becomes inaccessible. The athlete disappears.
PERFORMANCE DROPS
The moment passes. Potential was there. Access wasn't.
The CO₂ Tactics Method
MEASURE
BOLT and MBT tests establish your precise CO₂ tolerance baseline.
TRAIN
Targeted protocols build CO₂ tolerance. Stress ceiling rises.
ADAPT
The nervous system recalibrates. Composure becomes the new baseline.
PERFORM
Skills stay accessible under pressure. The trained athlete is the competitive athlete.
The Core Insight

Athletes lose access to their skills under pressure because stress capacity has never been trained. CO₂ Tactics is the first structured system to address this — measurably.

The Founders

Founded by Athletes Who Lived It

James Jones
James Jones
Former MLB Outfielder · Seattle Mariners
Co-Founder · CO₂ Tactics

James reached the majors as a center fielder with the Seattle Mariners, part of fifteen professional seasons that also took him through the Los Angeles Dodgers organization. An outfielder's career is long stretches of stillness broken by moments that demand everything at once — that gap between waiting and executing is where pressure does its damage.

Matt Magill
Matt Magill
Former MLB Pitcher · Dodgers, Reds, Twins, Mariners
Co-Founder · CO₂ Tactics

Matt pitched in the majors for the Dodgers, Reds, Twins, and Mariners over a fifteen-season professional career — every outing a chain of isolated, fully exposed decisions on the mound. He knows from the inside what separates how an arm works in the bullpen from how it works with the game on the line.

Members Only · Live · Monthly

Your Numbers,
Out Loud

Once a month, live. One focus, worked through real member data.

Members submit their data ahead of time. We pick the reads that show the month's focus best, put them on the screen, and coach them in front of everyone. You learn as much from someone else's numbers as from your own.

The System · In Your Hand

Your Numbers. Every Day.

The app runs your daily protocol, scores what you build, and keeps Matt and James one tap away. This is what opens after your trial starts.

The Science

Grounded in Science.
Validated by Research.

Stress capacity is a measurable, trainable system — physical and mental. CO₂ tolerance, nervous system regulation, focus, and emotional control are all variables we can baseline, train, and improve.

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 BOLT and MBT tests, 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. Breathing apps train a technique. Mental performance trains a mindset. We train stress capacity — the physical and mental system that decides whether your skill shows up under pressure. Most people call that grit and treat it like a personality trait. We treat it like a capacity: it has a baseline, it has a number, and it moves when you train it. Physical and mental, built together, measured every day. That's what makes it a different category, not a different label.

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 BOLT and MBT 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, you also get a monthly family session and a direct line to James or Matt 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 family session with a founder. 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 families watch their athlete's trends live in the monthly session.

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.
