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.
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.
Three steps. Two capacities — physical and mental. One outcome: skill that holds under pressure.
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.
Breathing protocols raise your stress ceiling. Focus and composure drills build the habits that hold under pressure. Two capacities. One system.
Composure holds. Decisions stay sharp. Skills remain accessible. The athlete who shows up in practice shows up when it counts.
What determines the outcome is whether the body has been trained to handle pressure.
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.
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 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.
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.
Included with The System · $49/mo
The System trains and reads you. Private is just us. The Flagship puts us in your building.
Train daily. Get read monthly. The app builds capacity between sessions — then once a month we put member numbers on the screen and coach what they're saying.
Under 18 — a parent or guardian reviews and signs first, from their own email.
Training starts at 14. If you’re younger, have a parent or guardian reach out to us directly at info@co2tactics.com.
Seasons are long — commit like one. Or take the free assessment first.
Everything in the app — plus a monthly family session with James or Matt, and a direct line between calls.
Nothing to pay today — billing starts after we meet.
Full roster on the system. Your staff on the coach console. Weekly director reports — and James and Matt in your building, running the system with your athletes in person.
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.
