Breathwork Training for Altitude & Endurance
Harness the science of better breathing to optimize your body’s engine. Elite mountaineers trust our training system on ascents of Everest, Denali, Aconcagua, and more because it delivers measurable results when they matter most.
Originally built for high-altitude climbers and ultra-runners, our protocols are designed to re-engineer your breathing for peak efficiency fundamentally. For any endurance athlete, this means:
Strengthening Your Respiratory System: We target and fortify your primary breathing muscles, including the diaphragm, to improve your air intake, SpO2, and reduce wasted energy with every breath.
Improving CO₂ Tolerance: Learn to delay the onset of breathlessness and maintain calm under intense physical stress, allowing you to push harder for longer.
Simulating High-Altitude Conditions: Our methods safely replicate the effects of hypoxic (low-oxygen) training to boost your stamina and accelerate recovery, giving you an undeniable performance edge.
The result is a more resilient, efficient, and powerful you—ready to perform at your peak capacity.
Train Your Breath Like You Train Your Body.

How our 3-Phase System Prepares You for Altitude
Our science-backed training system takes you from baseline assessment to altitude-ready.
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.
- Hypoxia: Low blood oxygen saturation limits performance & endurance.
- Respiratory Muscle Fatigue: Thin air forces your diaphragm and intercostals to work harder.
- Cognitive Fog: Reduced oxygen delivery can hinder focus, memory, and mental clarity.
- Irritated Airways: Dry, cold air may irritate airways — especially if you do not use your nose to inhale.

Hear From Our Clients
"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."
"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."
“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.”
“I just got back from Bolivia and successfully climbed two 5,000+ m peaks and two 6,000+ m peaks (including Illimani).
The breathwork program definitely helped. I felt less breathless than I had felt on recent climbs. The breathing techniques also helped me quickly recover during brief breaks during the ascents, as well as help me to relax each night to sleep quite well in the tents/refuges.”
“As both a high-altitude climber and a coach preparing others for mountain adventures, I can't overstate the value of Recal's breathwork training program. The structured approach equips climbers and trekkers with the tools they need to handle the challenges of altitude. Recal’s focus on simulating elevation conditions in a safe, progressive way builds not only physical preparedness but also the confidence needed to succeed.
I’ve seen firsthand how this program helps my athletes acclimatize more effectively, recover faster, and perform at their best.”
"In 2023 I attempted Aconcagua and failed. Before my 2024 attempt, I did Recal's breathwork training – and my experience was night and day. On the mountain, between the altitude and physical exhaustion, moments of panic could have easily spiraled out of control. Instead, I found myself leaning into the techniques I had practiced—transforming moments of fear into moments of control and composure.
I also felt a big difference in my physical training leading up to it. I noticed my training become more efficient and progress being made more quickly."
“My main concern was the altitude of Everest Basecamp, and I wanted to ensure at altitude myself and the trekking team would not suffer. Recal’s breathwork training really helped; the breathing techniques without a doubt helped us prepare. And not just preparation, but also when short of breath on the trek, some techniques Coach Anthony gave us to do at altitude massively helped our oxygen levels. Nobody teaches us the basics in life -- such as how to breathe. BUT now I’ve been taught this will continue to help me 24/7 at altitude or sea level! Coach Anthony was very hands on and his enthusiasm was great. Overall, this is a great service.”
“Peru was terrific — I completed the trek and made it to 15.2k ft. The importance of breathing only through my nose was invaluable, and I enjoyed the training videos and recommendations. I was able to breathe just through my nose for most of the trek (every once in a while I mouth-breathed, but then concentrated and reverted back to nose only). Thank you to Recal for all of your support!”
“You can feel the difference – I did, emphatically. The base assessment scores tell a story of vast improvement for me, and beyond those numbers, the Recal High Altitude Breathwork Training Course left me with two very stark takeaways that further justify the effort it takes. First, I found new ways to enter a flow state through proper breathing and healthy pressure on my diaphragm. This undoubtedly will stay with me forever. Second, I’ll always have these exercises to turn back to and the knowledge gained throughout the course to help me prepare for future expeditions. Bring on the mountains.”
“My primary concern going into Everest Base Camp was my breathing ability. Recal’s training gave me techniques to relax and deal with altitude. When I was struggling, I thought back to what I learned, and it regulated my breathing and de-stressed my body. This high altitude breathwork training was better than any physical training I did to prepare for EBC.”
“I saw a big difference in my endurance. During training, I did the stairs in the forest as part of my weekly effort and did so with a weighted backpack – in only a few weeks, I was able to be faster and less winded after and my recovery was much better as well. On November 8, with the breathwork training under my belt, I'm proud to say I summited Mera Peak in the Himalayas.”
“Going into the climb, I was a bit concerned that I may not have been exactly where I needed from a fitness perspective but 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.”
“The breathwork training was a game-changer for my trip to Nepal. I never at any time had an issue with breathing, oxygen saturation levels, or mental acuity. I have since incorporated more breathwork into my own fitness training back home.
Thanks to Anthony and Recal for showing me the path.”
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. I was fine and ready to climb. 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."
“Your training got me up Cotopaxi. 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.”
