Breathe to Perform
Nasal breathing and CO2 tolerance drills that raise your ceiling

You've trained your legs. You've trained your lungs' capacity. You've never once trained how you breathe — and it's quietly capping how hard efforts actually feel. Breathe to Perform is a practical guide to six breathing techniques that work with your training, not instead of it.

Inside, you'll find:

• The science in plain terms — why the "I need air" feeling is mostly a CO2 signal, not an oxygen shortage, and why that matters
• Six complete techniques — Nasal-Only Breathing, the CO2 Tolerance Table, Box Breathing, Diaphragmatic Breathing, Exhale-Focused Effort Breathing, and Post-Effort Recovery Breathing
• A "try it now" action for every technique — something concrete to test on your very next session
• An illustrative breath-hold ladder for building CO2 tolerance safely and gradually
• Honest caveats and real safety guidance — including where the evidence is solid and where it's still early
• A checklist for layering techniques into real training without overhauling anything overnight

This isn't about breathing "correctly." It's about training the one system that's been running on autopilot the whole time you were training everything else.
