BREATHBUILT™
You've trained everything but your breath.
Train the muscles that power it.
The diaphragm, the intercostals, the muscles that move your rib cage — they respond to training like any other muscle, and they weaken without it. BreathBuilt™ is the structured practice that makes them strong.
Start BreathBuilt — $2408 techniques. 12+ minutes a day. 8 weeks. No gear. Lifetime access.
You train your legs, your back, your grip. You have probably never once trained the muscles you use every moment of your life.
Breathing feels automatic, so it gets treated as fixed. It is not. The muscles that drive each breath are skeletal muscles, and the rib cage they move is a structure that can be stiff or supple. Both are trainable. Both decline when they are left alone.
BreathBuilt™ treats breathing for what it physically is: a function you can make stronger. Not a relaxation technique. Not a mood. A capacity you build.
WHAT BUILDS REAL BREATHING POWER
Two physical pillars
Breathing power rests on two things: strong respiratory muscles, and a rib cage that expands and moves freely. One without the other is half a breath.
Train the muscles and neglect the structure, and you have force with no room to use it. Open the structure and neglect the muscles, and you have range with nothing to drive it. BreathBuilt™ builds both, in sequence.
These two pillars are not given. They are earned.
The strongest version of your breath is not the one you were born with. It is the one you build.
THE PROTOCOL
Eight techniques. Twelve minutes. Eight weeks.
A structured daily practice that trains strength, expansion, and control in a deliberate order — not a grab-bag of exercises.
8
targeted techniques that build respiratory strength, lung expansion, and breath control.
12
focused minutes a day. A real practice, not a time sink.
48
day progressive plan, structured week by week, unlocking as you go.
No gear. No hyperventilation. No gimmicks. The seventh day of each week is yours — rest, repeat, or practice freely.
WHO IT IS FOR
Built for people who train.
This is for you if
- You are an athlete, freediver, martial artist, runner or performer who wants more respiratory capacity and endurance.
- You coach, and you want to train breathing as a physical skill rather than a vague cue.
- You want your breathing to stay strong and easy under load, not ragged.
- You are a MovNat Certified Trainer extending real physical competence into the breath.
This is not for you if
- You want a quick trick to calm down in the moment.
- You are looking for guided relaxation or a spiritual practice.
- You will not commit 12+ minutes a day for eight weeks.
- You want results without training for them.

01 — Foundations
Understand what you're training, and why
Short videos on the physiology most programs skip: ventilation versus cellular respiration, CO₂ tolerance, respiratory rate and longevity, nasal versus mouth breathing, and what a healthy breath actually is.
Grounded in published research — key studies cited in the lessons.
02 — Technique
Every exercise, demonstrated and coached
A video for each BreathBuilt™ exercise: the setup, the cues, and the errors to avoid, so you load the right structures the right way from day one.
03 — The 8-week program
A daily session that builds week over week
A guided practice each day, around twelve minutes, progressing in deliberate order so respiratory strength and mobility compound instead of plateau.
WHAT YOU TRAIN
The eight techniques
01
Maximum Inhale
Engages your full respiratory range, especially the upper muscles of respiration, and improves your ability to fully expand the rib cage.
02
Dynamic Maximum Inhale
Builds upper respiratory power and rib cage flexibility by repeatedly expanding from a near-full to a full state.
03
Full Lungs Short Hold
Increases inspiratory strength and lung volume by maintaining high intrapulmonary pressure and passively stretching the tissues of the rib cage.
04
Full Lungs Stretch Hold
Strengthens the entire range of the respiratory muscles and improves rib cage mobility, combining high-pressure breath-holding with gentle active stretches.
05
Resistance Diaphragmatic Breathing
Makes the diaphragm work harder on the inhale by fighting the resistance of a tightened abdominal wall. A strength exercise for the diaphragm itself.
06
Airflow Resistance Breathing
Strengthens both the inhalation and exhalation muscles by creating resistance to airflow, building respiratory control and endurance.
07
Slow Breathing
Develops fine motor control of all the respiratory muscles, with a strong downregulating effect on the nervous system.
08
Segmented Inhale Hold
Builds fine motor control of the inhale muscles and recalibrates respiratory rhythm to become slower and more relaxed, with real impact on tissue oxygenation.
+Breath Control in Motion (bonus) — Builds reflexive breath control in dynamic states — the bridge into performance, where strength and rhythm have to hold up under real-world movement.

WHAT CHANGES
Eight weeks in
You won't just know the techniques. Your breathing will physically work differently.
Breathing that holds up under load
When effort climbs, your breath stays full and controlled instead of turning shallow and ragged. The muscles feeding every hard moment are stronger, so they hold their form longer.
A fuller breath, with room to spare
A rib cage that expands further, and a diaphragm strong enough to use that range. You move more air with less effort, at rest and under exertion.
A stronger finish
Respiratory endurance you feel in the last third of a hard effort, where most people fade. You fade later.
Calm, as the bonus
Slow, controlled breathing downregulates the nervous system. It isn't what BreathBuilt™ sets out to do, but it comes with the work: a quieter baseline and a breath you can steady on command, earned through strength rather than chased as a mood.
THE PHYSIOLOGY
What the body actually does
Your respiratory muscles are skeletal muscles. Like every other skeletal muscle, they grow stronger under progressive load and weaker when nothing asks anything of them. The diaphragm and the intercostals can be trained for force and for endurance. The rib cage, and the tissue around it, can be trained for range.
BreathBuilt™ loads both, in a deliberate order, the way you would build any physical capacity. Nothing here is a trick or a supplement claim. It is strength and mobility training applied to the muscles and the structure that move air — the one system almost no program trains.
WHO BUILT THIS
The practice behind the records
I'm Erwan Le Corre, founder of BreathHoldWork®. I hold the U.S. National Record in Static Apnea, validated by the U.S. Freediving Federation — a record I have broken three times, with a personal best of 8 minutes and 3 seconds.
Those holds were not flukes. They were built on the same foundations you train inside BreathBuilt™: diaphragm strength, progressive lung expansion, and breath control under pressure.
BreathBuilt™ is not theory and it is not a performance. It is that physical groundwork, distilled into a protocol any serious person can follow.

QUESTIONS
Before you decide
Do I need any equipment?
No. Everything is trained with your own body. No bands, no devices, no gear of any kind.
How much time does it really take?
Twelve minutes a day, across eight weeks. The seventh day of each week is optional — rest, repeat, or practice freely.
Is this the same as the BreathHoldWork® Masterclass?
No, and they are not interchangeable. BreathBuilt™ trains the physical engine of breathing — the muscles and the rib cage. The Masterclass trains the nervous system and your response to stress. They complement each other; this is the physical foundation.
Is it safe? Do I need experience?
It is structured and progressive, with no hyperventilation and no extreme holds. Serious, but built to be followed step by step.
Do I keep access?
Yes. Lifetime access, including future updates.
Have a question before you decide?
Email me at [email protected]. It comes to me, and I answer every one personally.
Build a breath that holds up.
Eight weeks from now your breathing will be stronger than it has ever been — because you will have trained it.
