Let’s walk through it as if you’re starting Week 1 of training.

First: We test your breathing

You'll perform 3 breath assessment scores get a baseline for your breathing and track your progress:

  • Body Oxygen Level Test (BOLT)
  • Carbon Dioxide Tolerance Test (CO2TT)
  • Maximum Breathlessness Test (MBT)

Watch the video to get your own CO2TT score

Second: We outline the structure

There are two sides to your Breathwork Training.

  • High Altitude Simulation (HAS) Exercises

HAS exercises make adaptations in your body like a higher CO2 tolerance (to feel less breathless) and increased red blood cell count (to increase your oxygen uptake capacity). View the research here.

  • Respiratory Muscle Training (RMT) Exercises

RMT exercises strengthen the respiratory muscles (diaphragm, intercostals, and abdomen), which helps to keep your oxygen saturation levels higher at altitude. View the research here.

Watch the video to learn more

Third: You Start training

Now, it's time to dive into some exercises.

Breathe Light is an exercise designed to train your CO2 tolerance so you can feel less breathless on the mountain — and maintain an efficient breathing pattern when things get challenging.

Watch the video to do Breathe Light

Prep for HAS is one (of four) High Altitude Simulation (HAS) exercises in Week 1. Even though it's a warm-up exercise, it will give you a taste of what's to come.

Watch the video to do Prep for HAS

Exhale Pulsations is one (of two) Respiratory Muscle Training (RMT) exercises in Week 1.
This strengthens your abdomen and inner intercostal muscles (the ones you use to exhale), which helps with gas exchange at altitude and keeps your oxygen levels up.

Watch the video to do Exhale Pulsations

And you're off and running.

All you need to do now is choose how to integrate breathwork into your current fitness training.

Remember, this program is designed to be a complement (in addition) to your other training, and done during the pre-acclimatization block of training, i.e. the last 5 weeks before your endeavor in the mountains.

Why breathwork training? Hear from past clients:

Umer L.

Lahore, Pakistan → From 2,300 to 6,050 meters in 4 days, August 2024

“Thank you so much to Recal for the fantastic training. It has not only improved my adaptation to high altitudes but also made me aware and conscious of the importance of breathwork in my health. Your studies-based High Altitude Breathwork Training helped me prepare for the thin air of high altitudes while living and training in a concrete jungle - 200m above Sea Level. My eventual journey from 2300m to 6050m in just 4 days was as exciting as it was exhausting. I wouldn't recommend doing it this fast, but thanks to your training, I’m thrilled to have made it to the summit.”

Joshua B.

Alaska, USA → Leadville 100 Colorado, USA, August 2024

"I chose to participate in this training because I'm an endurance trail runner living at sea level, well versed in variable terrain and elevation gain, but unfamiliar with running at altitude. Since the training, I’ve seen improvements in my hill climb times and the ability to catch my breath after a steep, fast climb. While training, the biggest thing I gained is the ability to increase my pace while keeping my heart rate in my Zone 2. At Leadville 100, I felt great and performed very well. I believe there's much to gain from this training, whether as a climber, runner or biker."

 

Gordon H.

Alabama, USA → Bear 100 Ultramarathon, Utah, September 2024

“There was lots of climbing in the Bear 100 Ultra, and my breathing was great. The breathwork training prepped me for the altitude, and it established muscle memory in my diaphragm, which helped me immensely during some really gnarly climbs. The improved CO2 tolerance and respiratory muscle strength was essential to maintain a steady breath rate and recovering at the top of long climbs. This was a solid combination of mind and body training. For flatlanders like myself, this is indispensable for endurance events at altitude. Well worth the time and money.  

Jennifer F.

Oak Park, IL, USA → Mera Peak, Nepal, October 2024

"I attended a workshop and then purchased the 5-week training in preparation for my expedition at Mera Peak in Nepal. I am seeing a big difference in my endurance. I do the stairs in the forest as part of my weekly training effort and do so with a weighted backpack - nose breathing only and this week was able to be faster and less winded after. I'm seeing my recovery was much better as well. Thank you to Anthony and Recal!"  

Tim F.

Pennsylvania, USA → Mt. Rainier, Washington, July 2024

“Going into the climb, I was a bit concerned that I may not have been exactly where I needed from a fitness perspective. The Recal training filled any gaps I may have had. I credit the use of the tools from the program in making my climb successful and much more enjoyable than it would have otherwise been. I was also able to take what I learned in preparation for the mountains and apply it to my other lower elevation athletic activities.”  

Ron H.

Kansas City, USA → Mt. Cotopaxi, Ecuador, February 2024

“Breathwork training with Recal changed how I connected with Mt. Cotopaxi during my climb and also changed my relationship with my breath forever. When I awoke at 10:30 pm, one hour to start our journey up Cotopaxi, I had a headache and was concerned about my ability to climb. I quickly tested my blood oxygen levels and they were way too low. I anchored into all the training we had done to prepare and began to breathe deeply and fully. Just like we had talked about. In that moment, my blood oxygen levels jumped to 95. Of the challenges on that mountain, there was not one issue with altitude or my breath. My training had prepared me to oxygenate myself as I rose in altitude. I am so grateful for how this experience has changed my confidence with altitude and the power of my breath.”  

Catherine C.

Ontario Canada → Mt. Cotopaxi, Ecuador, February 2024

“Thank you to Anthony and Recal for your commitment to taking us through this process. I'm really grateful for the training - and personally felt like, as tough as it was, the alternative of suffering the consequences of not being prepared for this climb was worse. Your commitment and dedication comes through and you are a great teacher.”  

Dr. Raymundo, MD, IFMGA

International Federation of Mountain Guides Associations

“While guiding individuals who had recently trained with Recal, I was surprised at how well they were feeling – and moving quite fast for being at 5,000 meters – after not having been at any altitude months prior. The program seemed to improve their ability to keep hypoxic levels under control – which we monitored using a pulse oximeter – and an increase in oxygen uptake.

I saw, first-hand, these effects play out and was pleasantly surprised.”

READ THE ARTICLE IN MATADOR.

“You can feel the difference – I did, emphatically. The course taught me to push through what I previously believed to be my breaking point, and on my first long trek through the high alpine, I noticed a significant improvement in my performance.

Bring on the mountains.”

— Tim Wenger, Matador, September 2024

ALTITUDE TRAINING.
FROM ANYWHERE.

Whether you’re a sea-level dweller gearing up for a trek in Nepal, an ultra-marathon mountain runner, or an experienced climber eyeing your next summit, this program was specifically designed for you to train, at any elevation, and reach your goals.

So, what happens at altitude?

The partial pressure of oxygen decreases as you climb higher

This decrease in oxygen availability sets off a series of changes to your respiratory system. You may experience an increase in respiratory rate (breaths/min), increased heart rate, and decrease in oxygen uptake (VO2max). 

The higher you go, you might face these challenges:

  • Low oxygen saturation levels (hypoxia)
  • Respiratory muscle fatigue due to thin air and larger workload
  • Difficulty maintaining mental clarity

Learn how you can combat these effects with breathwork training.

With Recal, you will embark on a TRAINING to:

Improve your Breath Efficiency

Changing bad habits and improving the mechanics of your breathing is important to prevent severe hypoxia at altitude.

Make Physiological Adaptations

Using high altitude simulation breath protocols, you will make adaptations, including new red blood cells and higher CO2 tolerance to feel less breathless on the mountain.

Strengthen your Respiratory Muscles

Due to thinner air at altitude, your respiratory muscles must work harder to exchange air with each breath. You will strengthen your diaphragm, intercostal muscles, and abdomen.
