The Short Answer

Respiratory muscle training adds resistance to breathing so the muscles involved in inhalation and exhalation must work harder.

The On The Nose Co. AirFlow™ Cardio Trainer uses adjustable breathing resistance and is designed for short, repeatable sessions. It may help users train breathing control and respiratory muscle strength when used consistently.

Research suggests respiratory muscle training can improve inspiratory muscle strength and may improve exercise performance or reduce breathlessness in some athletes. Results vary, and a breathing trainer does not increase anatomical lung size, replace cardio training or treat a medical condition.

The Missing Training Piece

You Train Your Legs, Core and Heart. What About Your Breathing Muscles?

Breathing is automatic, but the muscles that drive it still perform physical work. During hard exercise, the diaphragm and supporting respiratory muscles must repeatedly contract against increasing demand.

  • Running and endurance sessions
  • HYROX and functional fitness
  • Cycling, rowing and swimming
  • High-repetition gym work
  • Combat and field sports

How AirFlow™ Works

A Simple Resistance-Breathing Process

1. InhaleBreathe through the mouthpiece using controlled technique.
2. ResistanceThe adjustable setting makes each breath more demanding.
3. Muscle WorkThe diaphragm and supporting breathing muscles work against load.
4. ConsistencyRepeat short sessions while gradually adjusting difficulty.
5. AdaptationOver time, respiratory strength and breathing control may improve.

Potential Training Benefits

Why Athletes Use Respiratory Muscle Trainers

Breathing Muscle Strength

Resistance provides an overload stimulus for the muscles used to breathe.

Breathing Control

Structured sessions encourage deliberate, repeatable breathing under resistance.

Exercise Tolerance

Some research reports improvements in exercise performance or perceived breathing effort.

Portable Training

A compact device can be used at home, at the gym or while travelling.

Adjustable Progression

Beginners can start lower and increase resistance gradually as technique improves.

Routine Building

Short sessions can be added to warm-ups, separate breathing sessions or recovery days.

Sport and Fitness Uses

Who May Benefit from Breathing Resistance Training?

Runners

Use respiratory training alongside easy runs, intervals and long-run preparation. Pair it with nose strips for running when external nasal support suits your routine.

HYROX Athletes

Mixed running and stations create sustained breathing demand, making structured respiratory practice relevant to event preparation.

Cyclists

Breathing training may complement aerobic conditioning and help users practise controlled breathing away from the bike.

Gym-Goers

Useful for high-repetition sets, circuits and conditioning sessions where breathing becomes a limiting sensation.

Swimmers and Rowers

Both sports require rhythm, timing and respiratory control alongside technique and conditioning.

Team-Sport Athletes

AFL, NRL, football and rugby involve repeated high-intensity efforts with short recovery windows.

A Realistic Progression

What the First Four Weeks May Look Like

Week 1

Learn the Technique

Start at low resistance and focus on smooth, controlled breathing.

Week 2

Build Consistency

Repeat short sessions and avoid rushing the breath.

Week 3

Progress Gradually

Increase resistance only when form remains controlled.

Week 4+

Maintain and Review

Track comfort, perceived effort and how breathing feels during exercise.

Individual responses vary. The timeline above is a training framework, not a promise of specific results.

Simple Weekly Routine

A Practical 5–10 Minute AirFlow™ Plan

Monday5 minutes at comfortable resistance. Focus on technique.
Tuesday5–7 minutes. Maintain steady, controlled breaths.
WednesdayRest or complete a light technique session.
Thursday5–8 minutes with a small resistance increase if comfortable.
FridayShort session before or separate from conditioning training.
SaturdayOptional maintenance session away from maximum exercise.
SundayRest, clean the mouthpiece and review the next week.
Progress RuleIncrease difficulty gradually—not every session.

The Science in Plain English

What Research Says About Respiratory Muscle Training

Inspiratory muscle training is a form of respiratory muscle training that places resistance on inhalation. Systematic reviews have reported improvements in respiratory muscle strength and potential performance benefits in some athletic groups, although protocols and results differ.

A widely cited systematic review found that respiratory muscle training could improve respiratory muscle strength and endurance and may improve sport performance. More recent reviews continue to report potential benefits, while emphasising differences between athletes, sports and training programs.

Respiratory training should complement—rather than replace—aerobic conditioning, strength work, recovery, sleep and sport-specific practice.

Important Safety Information

A Breathing Trainer Is Fitness Equipment, Not Medical Treatment

  • Stop immediately if you feel chest pain, faintness, severe dizziness or unusual breathlessness.
  • Do not use while driving, swimming or operating equipment.
  • Do not force maximum resistance or hold your breath for prolonged periods.
  • Seek medical advice before use if you have a diagnosed heart or lung condition, are pregnant, recently had surgery or have unexplained breathing symptoms.
  • Do not use the device as a treatment for asthma, COPD, sleep apnoea or another medical condition unless guided by a qualified clinician.
  • Clean the mouthpiece with warm water and mild soap, then allow it to dry fully.

Frequently Asked Questions

AirFlow™ Cardio Trainer FAQ

What is a respiratory muscle trainer?

It is a device that creates resistance while breathing so the respiratory muscles perform more work.

How does the AirFlow™ Cardio Trainer work?

It uses adjustable breathing resistance. The user breathes through the mouthpiece while maintaining controlled technique.

How often should I use it?

On The Nose Co. recommends short 5–10 minute sessions. Begin conservatively and build consistency before increasing resistance.

Can beginners use it?

Yes. Start at a low resistance and only progress when breathing remains smooth and controlled.

Can it improve endurance?

Research suggests respiratory muscle training may improve respiratory strength and may support performance in some users, but outcomes vary.

Does it increase lung capacity?

It trains the muscles involved in breathing. It should not be described as increasing the anatomical size of healthy adult lungs.

Is it useful for runners?

It may complement running training by providing dedicated respiratory resistance work away from the run itself.

Is it useful for HYROX?

HYROX combines running with high-output stations, so respiratory conditioning may be a useful accessory to structured event training.

Can cyclists use it?

Yes. Cyclists may use it as separate breathing-muscle training alongside normal riding and aerobic conditioning.

Should I use it during a workout?

Dedicated sessions are generally simpler and safer. Do not obstruct breathing during high-intensity exercise unless following qualified guidance.

Can it stop snoring?

It is not a treatment for snoring or sleep apnoea. Persistent loud snoring, gasping or breathing pauses require medical assessment.

How long until I notice a difference?

Responses vary. Track breathing control and training comfort over several weeks rather than expecting immediate changes.

How do I clean it?

Wash the mouthpiece regularly with warm water and mild soap, rinse and allow it to air dry completely.

Can multiple people share it?

For hygiene reasons, avoid sharing a mouthpiece unless the manufacturer provides a safe individual-mouthpiece system.

Does it replace cardio?

No. Respiratory muscle training should complement running, cycling, swimming, gym work or another suitable fitness program.
