What Are Breathing Trainers?
Common breathing trainer devices used for respiratory muscle training
Breathing trainers, also known as respiratory muscle training (RMT) devices, are specialized tools designed to strengthen the muscles involved in breathing-primarily the diaphragm and intercostal muscles. Similar to how you might use weights to strengthen your biceps, these devices create resistance when you breathe, forcing your respiratory muscles to work harder.
The concept originated in medical settings for patients with respiratory conditions but has expanded into the fitness and wellness markets. Vladimir Frolov, a Russian biochemist, developed one of the first breathing training devices in the 1990s after researching the Buteyko method-a breathing technique developed by Ukrainian doctor Konstantin Buteyko in the 1950s.
Modern breathing trainers typically fall into two categories:
Inspiratory Muscle Trainers (IMT)
These devices create resistance when you breathe in, strengthening the diaphragm and external intercostal muscles. They’re particularly popular among endurance athletes looking to improve performance.
Expiratory Muscle Trainers (EMT)
These focus on creating resistance when you breathe out, targeting the internal intercostal muscles and abdominal muscles. They’re often used in medical settings for patients with certain respiratory conditions.
Some advanced devices, like the Airofit Pro and Oumua Pro, offer both inspiratory and expiratory training capabilities, along with smart features that connect to mobile apps for tracking progress.
The Science of Respiratory Muscle Training
The scientific principle behind breathing trainers is straightforward: by creating resistance during inhalation or exhalation, these devices force respiratory muscles to work harder, eventually leading to increased strength and endurance-similar to resistance training for other muscle groups.
When you use a breathing trainer regularly, several physiological adaptations occur:
- Diaphragm hypertrophy: The diaphragm, your primary breathing muscle, becomes stronger and more efficient.
- Improved neural recruitment: Your nervous system becomes better at activating respiratory muscles during breathing.
- Enhanced respiratory muscle endurance: Your breathing muscles can work longer before fatigue sets in.
- Increased lung capacity utilization: You become more efficient at using your existing lung capacity.
- Reduced perceived breathlessness: Activities that once left you winded become easier to perform.
It’s important to note that breathing trainers don’t actually change your lung size or create new alveoli (air sacs). Rather, they improve the efficiency of the muscles that control breathing, allowing you to use your existing lung capacity more effectively.
Proven Benefits of Breathing Trainers
Athletic Performance Enhancement
Multiple studies have demonstrated that respiratory muscle training can significantly improve athletic performance. A 2012 Olympic study discovered that synchronized swimmers, who can hold their breath underwater for an average of one minute, ranked second only to long-distance runners in aerobic capacity.
A comprehensive meta-analysis published in the Journal of Sports Science & Medicine found that inspiratory muscle training improved endurance performance by an average of 11% across various sports, including running, cycling, swimming, and rowing.
One particularly revealing study by Markov et al. observed 37 sedentary participants divided into three groups: respiratory training, aerobic endurance training (cycling or running), and a sedentary control group. After 15 weeks, both the respiratory training and aerobic training groups showed significant endurance improvements compared to the control group, suggesting that respiratory muscle training alone can enhance performance.
“Respiratory muscle training works by providing resistance during inhalation and exhalation. Just like weight training at the gym, the added resistance strengthens the muscles that your body uses to breathe over time.”
– Dr. Michael Johnson, Sports Physiologist
Asthma Management
For individuals with asthma, breathing trainers may offer significant benefits. Research has shown that using respiratory muscle training devices can reduce breathlessness and alleviate asthma symptoms by strengthening the inspiratory muscles.
A study published in the European Respiratory Journal found that six weeks of inspiratory muscle training in asthma patients led to:
- Reduced use of rescue medication
- Decreased frequency of asthma attacks
- Improved quality of life scores
- Enhanced respiratory muscle strength
- Better control of breathing during exercise
- Reduced anxiety related to breathlessness
Stress Reduction and Sleep Improvement
Beyond physical performance, breathing trainers can help manage stress and improve sleep quality. By promoting diaphragmatic breathing and increasing respiratory control, these devices help activate the parasympathetic nervous system-responsible for “rest and digest” functions.
A 2019 study in the Journal of Clinical Sleep Medicine found that participants who used inspiratory muscle training devices for 30 minutes daily over eight weeks reported:
- Reduced time to fall asleep by an average of 15 minutes
- Decreased nighttime awakenings
- Improved overall sleep quality scores
- Lower daytime fatigue levels

While breathing trainers offer numerous benefits, it’s important to understand their limitations and potential risks:
Benefits
- Improved respiratory muscle strength and endurance
- Enhanced athletic performance, especially in endurance sports
- Potential reduction in asthma symptoms
- Better stress management and sleep quality
- Non-pharmaceutical approach to breathing improvement
Limitations & Risks
- Potential for hyperventilation if used incorrectly
- High-end devices can be expensive ($300+)
- Requires consistent use (5-10 minutes daily) for results
- May not benefit everyone equally
- Not a replacement for medical treatment for respiratory conditions
Important: If you have a respiratory condition such as severe asthma, COPD, or any cardiovascular disease, consult with a healthcare provider before starting respiratory muscle training. Improper use could potentially exacerbate symptoms in some conditions.
Common Misconceptions
“Breathing trainers will increase my lung size”
This is false. Breathing trainers don’t physically enlarge your lungs or create new alveoli. Instead, they strengthen the muscles that control breathing, allowing you to use your existing lung capacity more efficiently.
“Results will be immediate”
Like any form of strength training, respiratory muscle training requires consistency. Most studies show meaningful results after 4-8 weeks of regular use (5-10 minutes daily).
“More resistance is always better”
Starting with too much resistance can lead to improper technique, muscle fatigue, or even hyperventilation. It’s best to begin with lower resistance levels and gradually increase as your respiratory muscles adapt.
How to Use Breathing Trainers Effectively
Proper technique for using a respiratory muscle training device
To maximize the benefits of respiratory muscle training while minimizing risks, follow these guidelines:
Getting Started
