Mechanisms of Action Description

Autonomic Rebalancing (HRV ↑) – Respiratory Muscle Training increases parasympathetic tone (“rest and recover” system), promoting faster recovery and improved stress resilience after exercise.

Metabolic Recovery (Lactate ↓) – Strengthened respiratory muscles enhance oxygen delivery and carbon-dioxide buffering, accelerating lactate clearance and reducing acidosis after exertion.

Reduced Respiratory Strain & Perceived Fatigue (RPE ↓) – Respiratory Muscle Training decreases respiratory effort and sympathetic stress during exercise by reducing the work of breathing and attenuating the respiratory metaboreflex (blood-flow steal to respiratory muscles).

Enhanced Inspiratory Strength (MIP ↑) – Increased maximal inspiratory pressure improves breathing efficiency and reduces respiratory muscle fatigue during effort and recovery.

Respiratory Endurance (MVV ↑) – Improved sustained ventilatory capacity and resistance to respiratory muscle fatigue reduce systemic stress and accelerate post-exercise recovery.

Attenuated Respiratory Metaboreflex (↓ Sympathetic Overdrive) – Delays the reflex vasoconstriction of limb muscles caused by fatigued respiratory muscles, preserving oxygen delivery to working muscles and shortening recovery time.

Overall Recovery & Resilience Composite – Integrated autonomic, metabolic, and respiratory adaptations produce faster systemic recovery, lower stress load, and improved readiness for repeated performance.

How do I use it?

All you need is 5-10 minute sessions, 4-7 days a week breath training with your FITAIR PRO 2.0 device.

*Best practices, detailed regimens, and methodologies are outlined in our free eBook.*

Step 1: Insert the mouthpiece into your mouth as you would a mouthguard.

Step 2: Stand or sit comfortably in an upright position maintaining good posture.

Step 3: Twist the resistance adjustment knob at the end of the device to achieve your desired level of breathing resistance.

Step 4: Perform 2 sets of 10 full deep breaths. Work your way up to 2-4 sets of 30 breaths over the course of 2 weeks.

Note: Breath training can be performed simultaneously with various exercises. This is considered an advanced technique and we recommend this to people who are already conditioned athletes. Otherwise, we advise completing the 30-day regimen outlined in our eBook first.

What is breath training and how does it work?

Breath training is scientifically referred to as Respiratory Muscle Training (RMT). RMT encompasses Inspiratory/Expiratory Muscle Training (IMT/EMT). Targeting muscles that allow you to inhale vs exhale yield different results.

FITAIR PRO 2.0 is an advanced yet simple breath training device that allows the user to perform progressive targeted breath resistance training with our unique dual-resistance adjustment design.

FITAIR PRO 2.0 give you the flexibility to target your specific goals. Don't worry, comprehensive regimens are outlined for you in our free eBook guide. 💪🫁

Here is how it works:

1. Targeted Overload of the Breathing Muscles

RMT works on the same principle as strength training for any muscle group.

  • FITAIR create inspiratory & expiratory resistance (you have to work harder to inhale/exhale).
  • This overloads the diaphragm and intercostal muscles, stimulating adaptation and strength gains.
  • Over time, these muscles become stronger, thicker, and more fatigue-resistant.

2. Reduced “Oxygen Cost” of Breathing

Once stronger, your breathing muscles require less oxygen to function during exercise.

  • Normally, your respiratory system can consume up to 15–20% of total oxygen during intense exercise.
  • After RMT, this can drop by up to 30–40%, freeing more oxygen for your limbs and working muscles.
  • That’s what leads to measurable improvements in VO₂ max, endurance, and stamina.

3. Delayed Onset of Respiratory Muscle Fatigue

When breathing muscles fatigue, your body activates a metaboreflex — a protective reflex that diverts blood away from your limbs to preserve breathing.

  • Stronger respiratory muscles delay this reflex, meaning blood flow stays prioritized for performance.
  • The result: less overall fatigue and the ability to maintain intensity longer.

4. Improved Breathing Efficiency & Control

With consistent RMT:

  • Each breath moves more air with less effort (greater tidal volume).
  • Breathing rate slows and becomes more controlled, improving oxygen exchange efficiency.
  • Athletes experience steadier heart rate, lower perceived exertion, and better recovery between intervals.

Where is the science?

Important Note: Breath Training is scientifically referred to as Respiratory Muscle Training (RMT).

Direct scientific evidence for the 3 core benefits of RMT is listed in dropdowns above.

There are 1000s of published clinical & independent research studies documenting the effects of RMT on sports performance & respiratory health. We have done our due diligence and only showcase the latest and greatest research.  

Below is a credible meta-analysis of 46 different research studies on the effects of RMT on physical performance. The analysis concludes that RMT improves endurance performance. 

Next is an article published in the Strength & Conditioning Journal in December of 2024 by Tomasz Kolwalski, a top Physiologist at the National Institute of Sport Research in Warsaw, Poland.

 In the article he discusses why RMT is still unknown to many conditioning coaches despite state-of-the-art literature reviews concluding the significant positive effects it has on sports performance. He then goes on to describe the practical applications of RMT for specific sports.

The primary benefits

Backed By Real Published Science.

RMT improves endurance and cuts breathlessness

Training your breathing muscles improves endurance performance, boosts breathing muscle strength/endurance, and makes efforts feel easier (less breathlessness), including in tough settings like altitude. This comes up repeatedly in the applied review for coaches and is backed by controlled work it summarizes. 

RMT builds stronger breathing muscles that predict higher VO₂ Max

Across competitive athletes, measures of respiratory muscle strength, especially maximal expiratory pressure (MEP) were significant predictors in models explaining about 51% of the variance in VO₂max/kg. Translation: the stronger your breathing “engine,” the higher your ceiling for aerobic fitness tends to be.  

RMT delays a “blood-stealing” reflex from tired breathing muscles (metaboreflex)

When the breathing muscles fatigue, the body can reflexively redirect blood toward them and away from your legs/arms, which hurts performance. RMT seems to toughen those muscles so they fatigue later, blunting this reflex and helping you keep more blood flow for working limbs.

 RMT improves performance across many sports, from endurance to combat disciplines

Across multiple studies, respiratory muscle training (RMT) produced measurable improvements in both aerobic and anaerobic sports. Swimmers increased their underwater distance and stroke efficiency after inspiratory training, while cyclists and runners experienced faster recovery and reduced perceived effort during intense exercise. Even athletes in strength and endurance hybrid disciplines like judo and cross-country skiing showed that stronger breathing muscles correlated with higher VO₂ max and greater power output. In simple terms, whether it’s long races or short explosive bouts, stronger lungs consistently translate into better performance.

 RMT strengthens the diaphragm and core, improving posture and movement

Slow, controlled breathing through trained muscles doesn’t just affect performance, it also improves recovery and mental calm.

RMT enhances parasympathetic activation (the “rest and recover” system), helping athletes relax faster, sleep better, and manage pre-race stress.

 RMT strengthens the diaphragm and core, improving posture and movement

Respiratory Muscle Training (RMT) improves how efficiently you breathe when oxygen demand is high, like during intense workouts, sprints, or training at altitude. Research shows that athletes with stronger respiratory muscles use less oxygen for the same effort, meaning their bodies stay calmer and more efficient under stress. This training delays the point where you start gasping for air, maintains steadier oxygen delivery to your working muscles, and keeps fatigue at bay for longer. In short, RMT helps you stay in control of your breathing, and your performance, even when the pressure peaks.

FAQs

What is breath training & how does it work?

(Please read the scientific evidence outlined in the drop downs above.)

The FITAIR PRO 2.0 strength trains the respiratory muscles via breath resistance. A process scientifically referred to as Respiratory Muscle Training (RMT).

In addition to RMT, The FITAIR PRO 2.0 also doubles as a breathwork practice due to the controlled breathing exercises. We refer to the combination of both as breath training.

Stronger respiratory muscles provide several benefits, including improved breathing efficiency, reduced breathlessness, and enhanced oxygen delivery to the body's tissues. This leads to better overall physical performance and endurance, especially in athletes.

For individuals with respiratory conditions such as COPD or asthma, stronger respiratory muscles can significantly alleviate symptoms, making daily activities easier and improving quality of life. Additionally, enhanced respiratory muscle strength can aid in quicker recovery from respiratory illnesses and help maintain lung function as we age.

Respiratory muscles are typically only strengthened through intense prolonged cardiovascular exercise. Therefore, strength training your respiratory muscles allows you to quickly and easily improve your physical fitness and overall well being.

Furthermore, it is possible to achiever a higher degree of respiratory muscle strength with RMT than with just cardiovascular exercise alone because of the added resistance. It is the same principle as strength training your skeletal muscles with added weight vs only body weight. For example, you will not be able to achieve the same degree of strength with bodyweight squats as you can with weighted squats. This is why even the most conditioned endurance athletes can benefit from breath training.

How do I use it?

All you need is 5-10 minutes a day breath training with your FITAIR PRO 2.0 device.

*Best practices, detailed regimens, and methodologies are outlined in our free eBook.*

Step 1: Insert the mouthpiece into your mouth as you would a mouthguard.

Step 2: Stand or sit comfortably in an upright position maintaining good posture.

Step 3: Twist the resistance adjustment knob at the end of the device to achieve your desired level of breathing resistance.

Step 4: Perform 2 sets of 10 full deep breaths. Work your way up to 2-4 sets of 30 breaths over the course of 2 weeks.

Note: Breath training can be performed simultaneously with various exercises. This is considered an advanced technique and we recommend this to people who are already conditioned athletes. Otherwise, we advise completing the 30-day regimen outlined in our eBook first.
