How it Works

Week-by-Week Course Breakdown

The Recal 5-week program is fully digital and self-paced, with new sessions unlocking weekly.

Intro & Breathing Mechanics

In Week 1, you will establish your baseline breath assessments, which will help you track your progress over the 5 weeks. You will also learn foundational breathwork protocols that will be key to your training.

Start with the fundamentals. You’ll learn—and develop muscle memory for—how to breathe Nose, Slow, and Low (N-S-L) to optimize oxygen uptake and nervous system regulation. This is the foundation for everything else.

  • Respiratory Muscle Training and High Altitude Simulation Exercises.
  • Video description of what to expect for the week​​
  • Demo videos of each exercise​

CO₂ Tolerance Protocols

Week 2 will build on the foundational breathwork exercises and incorporate more sport-specific movements (including uphill terrain)

We introduce CO₂ tolerance training and intermittent hypoxia to simulate altitude stress. You’ll experience what breathlessness feels like—and build your tolerance to it, safely.

Respiratory Muscle Training​

Week 3’s goal is to build mental resilience and acuity in the face of breathlessness. We also introduce the use of the SportsMask.

This is strength training—for your breath. You’ll begin inspiratory and expiratory muscle exercises that condition your diaphragm and intercostals, improving stamina and recovery under load.

Elevate your Performance​

This week brings together all three parts of your training: better breathing mechanics, adaptation protocols, and respiratory muscle training. This will be the most challenging – and rewarding – week of training.

And now, you get to put your new skills to the test on the mountain.

Mountain Application & Recovery

In the final days, we share tips on breathing techniques during your mountain adventure, plus Recovery Breathing protocols and exercises to combat altitude sickness. We also share the long-term benefits of breathwork for life beyond the mountain.

This isn’t just for training before your event; you will learn the most effective way to breathe ON the mountain. We also share our suite of recovery breathing protocols (featuring the 3 R’s: Re-oxygenate, Re-acidify, Reboot) for muscle recovery and to aid your acclimatization process.

The only equipment you NEED are your breath and body.

But we'll make a few suggestions that complement the training.

What Happens to Your Body at Altitude?

As you climb higher in altitude, several key physiological changes occur in your body — particularly in your respiratory system — that make everything feel harder.

Trackable Progress

Throughout the course, we’ll teach you how to assess and track your progress using five simple tests:

BOLT

Body Oxygen Level Test

CO2TT

Carbon Dioxide Tolerance Test

MBT

Maximum Breathlessness Test

LOM

Location of Movement

ROM

Range of Movement

By the end of the course, you’ll see measurable improvements—not just in numbers, but in how you feel when you train, recover, and climb.

What You’ll Do

Over five weeks (or longer if you have the time), you’ll dive into the core pillars of our B.A.S.E. Framework:

Better Breathing Mechanics

(B in B.A.S.E.)

Start with the fundamentals. You’ll learn—and develop muscle memory for—how to breathe Nose, Slow, and Low (N-S-L) to optimize oxygen uptake and nervous system regulation. This is the foundation for everything else.

Adaptation Protocols

(A in B.A.S.E.)

We introduce CO₂ tolerance training and intermittent hypoxia to simulate altitude stress. You’ll experience what breathlessness feels like—and build your tolerance to it, safely.

Respiratory Muscle Training

(S in B.A.S.E.)

This is strength training—for your breath. You’ll begin inspiratory and expiratory muscle exercises that condition your diaphragm and intercostals, improving stamina and recovery under load.

And now, you get to put your new skills to the test on the mountain. 

On-Mountain and Recovery Protocols

BONUS

This isn’t just for training before your event; you will learn the most effective way to breathe ON the mountain. We also share our suite of recovery breathing protocols (featuring the 3 R’s: Re-oxygenate, Re-acidify, Reboot) for muscle recovery and to aid your acclimatization process.
