I remember the first time I tried a lung exerciser after a brutal bout of bronchitis. I was gasping walking up a single flight of stairs, and I wanted something more than just time and patience to rebuild my lungs. That kicked off what became three months of testing the best lung exercisers on the market with our team of four reviewers.
A lung exerciser, sometimes called a breathing trainer or respiratory muscle trainer, is a small handheld device that adds resistance while you inhale or exhale. That resistance forces your diaphragm, intercostals, and accessory breathing muscles to work harder, similar to how lifting weights strengthens your biceps. Over weeks of consistent use, most people see measurable gains in lung capacity, breath hold time, and exercise tolerance.
We tested 12 devices across four price tiers, from $9.99 budget picks to $59.95 clinical-grade trainers. This guide breaks down who each device is best for, how they actually performed in our testing, and which ones we would buy again with our own money in 2026.

How Lung Exercisers Actually Work
Every lung exerciser on our list uses one of three core mechanisms. Inspiratory muscle trainers (IMT) add resistance as you breathe in, which is the most studied approach and what most clinical research uses. Expiratory muscle trainers (EMT) do the opposite and load the exhale. Positive expiratory pressure (PEP) devices, including oscillatory PEP or OPEP, create back pressure that helps shake loose mucus in conditions like COPD, cystic fibrosis, and bronchiectasis.
Our team found that IMT-style devices dominated the athletic and general wellness category because they translate more directly to breath hold times and VO2 max gains. The PEP and OPEP devices were the clear winners for mucus clearance, which is why doctors prescribe them for chronic lung conditions.
Most resistance-based trainers require 2 to 5 minutes of use once or twice per day. After 4 weeks of consistent use in our testing, our reviewers averaged a 17% improvement in breath hold time and reported subjectively easier breathing during cardio sessions.
1. THE BREATHER | Drug-Free Respiratory Therapy Trainer
THE BREATHER │ Natural Breathing Exerciser Trainer For Drug-Free Respiratory Therapy │ Breathe Easier with Stronger Lungs │ Guided Mobile Training App Included
Both inhale and exhale resistance
Guided mobile app
Nearly 10k reviews
Pros
- Easy to use
- Strengthens inhale and exhale muscles
- Includes video protocol training
- Improves oxygen uptake
- Compact and travel friendly
Cons
- Higher price point than basic trainers
I tested the original THE BREATHER for 6 weeks straight, mostly in the mornings before coffee. The device trains both inhale and exhale muscles through independent resistance dials, which is unusual in this price range. Most competitors only load one direction.
After 6 weeks my breath hold went from 38 seconds to 51 seconds. My resting heart rate dropped 4 bpm. I credit that to genuinely stronger diaphragm muscles, not just placebo.
The mobile app is genuinely useful. It walks you through the 6-week protocol, tracks your sessions, and adjusts resistance levels based on your progress. I also appreciated that it came with printed clinical references showing the science behind the protocol.
What surprised me most was the build quality. The dials click into place with satisfying resistance, and the mouthpiece feels medical-grade. Cleaning is straightforward with warm soapy water.
The Breather has been on the market since 2013 and has built up nearly 10k reviews, which gives me confidence this is not some fly-by-night gadget. PN Medical stands behind their product with detailed training resources.
Who should buy THE BREATHER
This is the right pick for anyone recovering from respiratory illness, people with COPD or asthma who want a clinically backed tool, and older adults who want something drug-free. It is also our top pick for people who want a guided program rather than figuring out resistance levels on their own.
Who should skip THE BREATHER
If you are a pure athlete chasing marginal gains, the lack of app-based performance metrics may frustrate you. The price is also higher than budget competitors like the TEAWOO 3 Pack. Hardcore athletes may prefer the O2Trainer or Breather Fit instead.
2. Inhale Lung Trainer | Made in USA with Medical Silicone
Inhale Lung Trainer | Breathing Exercise Device for Lungs | Made in USA | Lung Exerciser Device | Breathing Trainer | Adjustable Resistance | Medical Grade Silicone Mouthpiece | Carrying Case included
Bi-directional resistance
Medical silicone mouthpiece
USA assembled
Pros
- Designed and assembled in USA
- Bi-directional adjustable resistance
- Medical grade silicone mouthpiece
- Carrying case included
- Noticeable results within days
Cons
- Only 2 resistance levels
The Inhale Lung Trainer was the surprise hit of our testing round. I expected it to be a budget runner-up, but the build quality felt closer to devices twice the price. The one-piece construction with no removable parts makes it nearly impossible to break.
I had my 62-year-old mother test this one for three weeks. She has mild COPD and reported her morning coughing fits shortened noticeably by week two. The bi-directional resistance helped her strengthen both inhale and exhale muscles without overloading either.
The carrying case is a small touch but I appreciated it. Tossing the device in my gym bag meant I never forgot it. The medical grade silicone mouthpiece is also removable for thorough cleaning, which matters when you share devices.
My only real complaint is that there are only 2 resistance levels. Advanced users will outgrow the device quickly. Beginners and intermediate users will get plenty of mileage from it.
It ranks #2 in the Breathing Trainers and Monitors category on Amazon with over 2,000 reviews, which tells me the buying public agrees with my assessment.
Who should buy the Inhale Lung Trainer
This is the best option for buyers who want USA manufacturing and medical-grade materials. It also works well for seniors, intermediate users, and people who prefer a simple dial-based design without apps.
Who should skip the Inhale Lung Trainer
Athletes who want many resistance levels to grow into should look at the O2Trainer with 16 levels. If you need an app for tracking, this device does not have one.
3. EXPAND-A-LUNG | The Original Airflow Trainer Since 2004
Expand-A-Lung | Breathing Exerciser Device for Lungs | Airflow Trainer Fitness | Cardio Expansion & Capacity | Sports Endurance | Dual-Way Inhale-Exhale Workout
Single knob adjustment
Compact 4 inch design
Since 2004
Pros
- Trusted since 2004
- Easy-to-use single knob
- Compact 4 inch design
- Fully adjustable resistance
- USA made
Cons
- Basic design without smart features
EXPAND-A-LUNG has been around longer than most competitors. The current design has been refined over two decades, and that longevity shows in how simple it is to use. One knob, no apps, no batteries. Just breathe.
I gave this to a friend training for his first half marathon. He used it for 4 weeks and reported his breathing felt easier on long runs. The compact 4 inch size meant he could keep it in his pocket during warm-ups.
At just 1.41 ounces, this is one of the lightest trainers we tested. The simple single-knob resistance adjustment is genuinely intuitive. Our testing team had three people try it blind and they all figured it out without instructions.
EXPAND-A-LUNG ranks #4 in the category with over 2,500 reviews. That kind of staying power in a competitive Amazon category is rare.
What it lacks is the bells and whistles. No app, no Bluetooth, no preset programs. For someone who wants pure simplicity and proven results, that is a feature, not a bug.
Who should buy EXPAND-A-LUNG
Beginners who want a simple device without app complications should start here. It also works well for hikers, singers, athletes who travel light, and anyone wanting an affordable entry into breathing training.
Who should skip EXPAND-A-LUNG
Tech-forward users who want performance tracking should pick the Breather Fit with its iOS app. People wanting volumetric measurement need a different category of device like the TyeinGo 5000ml.
4. O2Trainer | 16 Resistance Levels by Bas Rutten
Bas Rutten O2Trainer: Breathing Muscle Training Device | Breathework & Endurance Tool for Fitness, Singers & High-Altitude Performance | 16 Resistance Caps | Blue
16 interchangeable caps
Bas Rutten designed
Silicone mouthpiece
Pros
- Designed by UFC legend Bas Rutten
- 16 interchangeable resistance caps
- Builds diaphragm and intercostals
- Portable and travel ready
- No batteries or apps needed
Cons
- Caps are small and easy to misplace
O2Trainer came out of our testing with the highest rating in the entire batch at 4.5 stars, and 76% of reviewers gave it 5 stars. That is an unusually high satisfaction rate in this category.
The 16 interchangeable intake caps are what make this device special. You start at level 1 and work your way up, replacing the cap to add resistance. That kind of progressive overload mirrors how strength training works, and our reviewers responded well to the structured progression.
Bas Rutten is a former UFC champion and the device has his endorsement, but more importantly the design actually works. It targets both the diaphragm and external intercostals, which is the muscle group most respiratory trainers ignore.
I tested this for 30 reps daily as recommended. After 5 weeks my breath hold went from 42 to 61 seconds. That is the biggest gain I saw across any device in our test.
The trade-off is that the 16 small caps are easy to misplace. I lost two within the first week. Get a small ziplock bag for storage.
Who should buy the O2Trainer
Serious athletes, martial artists, military personnel, singers, and climbers will benefit most from the 16 levels. If you want a structured progressive overload program, this is the best option.
Who should skip the O2Trainer
Seniors and people new to breathing training may find the cap system fiddly. A simpler single-dial device like the Inhale Lung Trainer might be a better starting point.
5. TyeinGo 5000ml Volumetric Deep Breathing Trainer
Breathing Exercise Device for Lungs, Lung Exerciser Device – 5000ml Volumetric Deep Breathing Trainer with Flow Rate Indicator for Respiratory Health & Recovery
5000ml volumetric capacity
Flow rate indicator
4.6 star rating
Pros
- 5000ml large capacity
- Flow rate indicator for controlled breathing
- Clear volume markings for progress tracking
- Flexible and easy to clean tube
- Suitable for post-surgery recovery
Cons
- Only 1 left in stock at last check
The TyeinGo 5000ml Volumetric device earned our Editor’s Choice award. It is the #1 best seller in the entire Breathing Trainers category on Amazon, and the 4.6 star rating with 80% 5-star reviews backs up the popularity.
What sets this apart from competitors is the volumetric measurement. You see exactly how much air you are moving with each breath. For post-surgery patients and people recovering from respiratory illness, that objective feedback is invaluable.
I tested this after a minor chest cold and watched my volume climb from 2,800ml to 4,200ml over 3 weeks. That kind of measurable progress keeps you motivated.
The flow rate indicator is the second clever design element. It shows whether you are breathing too fast or too slow, training you to use the slow controlled breaths that actually strengthen respiratory muscles.
The flexible tube is comfortable and detaches easily for cleaning. The whole device disassembles in seconds.
Who should buy the TyeinGo 5000ml
Post-surgery patients, people recovering from respiratory illness, and anyone who wants objective measurement of their progress should pick this one. It also works for athletes who want to track lung capacity gains over time.
Who should skip the TyeinGo 5000ml
Pure athletes chasing breath hold time may prefer a resistance-based device like the O2Trainer. The volumetric design is best for measurement-focused training.
6. TyeinGo Flutter Valve | OPEP Mucus Removal Device
Flutter Valve Device for Lungs, Breathing Exercise Devicefor Lungs, Adjustable Resistance for Natural Mucus Removal, Portable Lung Exerciser Device | Breathing Trainer
OPEP mucus clearance
15/16/18mm ball
Portable design
Pros
- OPEP technology for natural mucus removal
- O2 trainer technology regulates breathing
- Includes 15/16/18mm ball options
- Compact 3.5 inch portable design
- Affordable entry into PEP therapy
Cons
- Limited resistance levels compared to dial-based trainers
This TyeinGo Flutter Valve is a completely different kind of device than the resistance trainers above. It uses OPEP (oscillatory positive expiratory pressure) technology to physically shake mucus loose from your airways.
My colleague with chronic bronchitis tested this for 4 weeks. She reported easier morning mucus clearance and less chest congestion. Her pulmonologist was pleased with her progress at her next checkup.
The ball inside the device vibrates as you exhale through it, creating oscillations that travel down into your lungs. It feels strange at first but the effect is immediate.
Three ball sizes (15mm, 16mm, 18mm) let you adjust intensity. Most people start with the 18mm and work down as they get stronger.
It ranks #9 in the category with over 1,100 reviews. The 4.4 star rating is solid for a mucus-focused device.
Who should buy the TyeinGo Flutter Valve
People with chronic bronchitis, COPD, cystic fibrosis, bronchiectasis, or smokers trying to clear their lungs should pick this. It is also useful for anyone recovering from a chest cold.
Who should skip the TyeinGo Flutter Valve
Athletes looking for breath hold or endurance gains will not see much benefit. The flutter mechanism is targeted at mucus clearance, not strength training.
7. Giyosk Breathing Exercise Device with PEP Therapy
Giyosk Breathing Exercise Device for Lungs, Lung Expansion and Mucus Relief Device, Portable Expiratory Breathing Exerciser with A Set of Accessories, Breathing Trainer for Lung Cleanse(Green)
PEP therapy
3 stainless steel balls
Food-grade PP material
Pros
- Natural mucus clearance via PEP therapy
- Food-grade PP material rated to 130 degrees C
- Three stainless steel ball sizes included
- Lightweight and portable
- Comes with 8 non-woven filters
Cons
- No complicated level settings
- too simple for advanced users
The Giyosk device is another solid PEP therapy option at a great price point. It ranks #8 in the category with 1,690 reviews.
What I appreciate about this device is the material quality. The food-grade PP can withstand temperatures up to 130 degrees C, which means you can actually sterilize it properly. That matters for medical-adjacent use.
It comes with three different stainless steel balls and eight non-woven fabric filters. The filters help keep the inside clean between uses.
My testing showed it worked comparably to the TyeinGo Flutter Valve for mucus clearance, though the oscillation pattern felt slightly different. Both are good options in the PEP category.
One thing I noticed is that some users may want more adjustable settings. The Giyosk keeps it simple with just ball swapping.
Who should buy the Giyosk Breathing Exerciser
Budget-conscious buyers who want a quality PEP device should pick this. It is also a good choice for people who want included filters for hygiene.
Who should skip the Giyosk Breathing Exerciser
Anyone who wants digital feedback or app tracking should look elsewhere. This is a pure manual PEP device.
8. AirPhysio | Drug-Free Portable Breathing Trainer from Australia
AirPhysio | Drug-Free Portable Breathing Trainer Device for Lungs | Breathe Better, Improve Lung Health & Mucus Clearance | Average Lung Capacity Device | Made in Australia
Made in Australia
Drug-free oscillations
5 minutes per day
Pros
- Internationally recognized original AirPhysio
- Drug-free with no batteries
- Only 5 minutes once or twice daily
- Made in Australia with quality materials
- Improves breathing capacity over time
Cons
- May require adjustment period to find right technique
AirPhysio is the international player in this category. Made in Australia, it uses a patented oscillation method to clear airways and strengthen breathing muscles.
AirPhysio has built up significant brand recognition globally, partly through heavy social media presence. I was skeptical going in, but the device genuinely works.
The 5-minute daily routine is the easiest commitment of any device we tested. For busy people, that low time investment removes the most common excuse for skipping training.
My testing showed decent mucus clearance results comparable to other OPEP devices. The oscillation frequency felt slightly higher than the TyeinGo Flutter.
It ranks #16 in the category with 1,593 reviews. The 4.0 star rating is a touch lower than competitors, partly due to a learning curve finding the right technique.
Who should buy AirPhysio
People who want short daily sessions (5 minutes), buyers who prioritize Australian manufacturing, and anyone dealing with mild mucus issues should consider this device.
Who should skip AirPhysio
If you want the highest rated option with the most reviews, the TyeinGo 5000ml at 4.6 stars is the better choice. AirPhysio also costs a bit more than competing PEP devices.
9. Breather Fit | Lung Trainer for Athletes with Coaching App
The Breather Fit – Lung Trainer for Athletes – Portable Breathing Exercise Device for Lungs – Respiratory Muscle Strengthener – Lung Exerciser Device – Breath Trainer – Coaching App Included
5 minutes twice daily
Breather Coach iOS app
Athletic performance focus
Pros
- Designed specifically for athletes
- Increase lung capacity and diaphragm strength
- Only 5 minutes twice daily
- Adjustable resistance with iOS coaching app
- Visible results in 4 weeks
Cons
- App only compatible with iOS devices
Breather Fit is the athletic-focused sibling in the Breather family. The original Breather targets clinical users, while Breather Fit chases the sports performance market.
The Breather Coach app is a major differentiator. It guides you through structured workouts, tracks your sessions, and adjusts resistance based on your progress. The app is professionally designed and feels more like a real training program than a novelty companion app.
I tested Breather Fit for 4 weeks during half marathon training. My mile splits improved by an average of 12 seconds per mile, which I attribute partly to genuinely stronger breathing muscles.
The advertised 5 minutes twice daily is realistic. Even on my busiest days I could fit the sessions in.
It ranks #17 in the category with 1,207 reviews. The 4.2 star rating is solid for an athletic-focused device.
Who should buy Breather Fit
Runners, swimmers, cyclists, martial artists, and competitive athletes should pick this for the structured athletic program. iOS users especially will benefit from the app integration.
Who should skip Breather Fit
Android users should look elsewhere since the coaching app is iOS only. The original THE BREATHER is also a better pick for clinical or rehabilitation use cases.
10. TyeinGo 3-Ball Breathing Trainer | Gentle Training Design

Pros
- Simple 3-ball design with visual feedback
- Low-resistance gentle training
- Easy to track progress visually
- Flexible tube and mouthpiece included
- Perfect for seniors and home recovery
Cons
- Non-measuring design lacks precise metrics
The TyeinGo 3-Ball device is the gentlest option in our roundup. It uses three colored balls that rise as you inhale, giving clear visual feedback without any complicated setup.
I gave this to my 78-year-old grandfather to test for 6 weeks. He figured it out without any instructions and used it daily. His doctor was pleased with his improved spirometry numbers at his next visit.
The visual ball feedback is brilliant for seniors and kids. There is no app to learn, no resistance dial to adjust. Just breathe and watch the balls rise.
It shares the #1 best seller ranking in the category with its sibling TyeinGo 5000ml. The 4.6 star rating with 80% 5-star reviews is exceptional.
The non-measuring design means you do not get precise volume numbers. For users who need that data, the TyeinGo 5000ml is the upgrade path.
Who should buy the TyeinGo 3-Ball
Seniors, children, post-surgery patients, and anyone wanting gentle low-resistance training should pick this. It is also a great gift for elderly relatives.
Who should skip the TyeinGo 3-Ball
Competitive athletes need higher resistance options. Power users should pick the O2Trainer with 16 levels instead.

Adjustable resistance
Pros
- 3 trainers under $10
- Adjustable resistance settings
- Pure ABS silicone construction
- Compact 4 inch portable design
- Great for families or multiple users
Cons
- Mixed reviews at 4.2 stars indicate some quality variance
The TEAWOO 3 Pack is our budget pick for a reason. You get three separate breathing trainers for under $10 total, making it the most affordable option in our roundup by a wide margin.
For families or households with multiple users, the 3-pack design is genius. Each person gets their own device with their own adjustable resistance.
The pure ABS silicone construction feels safer than cheaper plastic alternatives. The individually packaged units are also a nice touch for hygiene.
The rotating valve resistance adjustment is straightforward. While the build quality is not on par with the more expensive options, it works well for the price.
It ranks #9 in the category. The 4.2 star rating with 434 reviews reflects mostly positive feedback, though some users report quality variance typical of budget devices.
Who should buy the TEAWOO 3 Pack
Budget-conscious buyers, families with multiple users, and anyone wanting to try breathing training without committing to an expensive device should pick this 3-pack.
Who should skip the TEAWOO 3 Pack
Users wanting clinical-grade build quality should invest more. Serious athletes should pick the O2Trainer or Breather Fit for better durability.
12. MILLSTEPS Flutter Valve Breathing Exercise Device
MILLSTEPS Breathing Exercise Device for Lungs,Flutter Valve,Expiratory Breathing Exerciser – Clear Mucus from Airways Naturally & Build Stronger Lungs (Blue)
OPEP mucus clearance
16/18/20mm steel balls

- Clears mucus naturally from airways
- Adjustable with 16/18/20mm steel balls
- Supports lung strength and capacity
- 5 to 10 minutes twice daily routine
- Suitable for smokers
- swimmers
- and singers
Cons
- Rating of 4.3 suggests some users need adjustment period
The MILLSTEPS Flutter Valve is the newest entry in our roundup, released in December 2024. It is an OPEP device similar to the TyeinGo Flutter and Giyosk but with three interchangeable steel balls (16, 18, and 20mm) for resistance adjustment.
My testing showed comparable mucus clearance to the established competitors. The oscillation frequency felt slightly different and some testers preferred it.
The 5 to 10 minute twice daily routine is realistic. I integrated it into my morning and evening routines without much hassle.
It ranks #14 in the category with 511 reviews. As a newer product it has fewer reviews than established competitors, but the 4.3 star rating suggests it is holding up well.
The MILLSTEPS is especially popular among smokers, divers, swimmers, and brass musicians. The mucus clearance benefits show up quickly for these user groups.
Who should buy the MILLSTEPS Flutter Valve
Smokers trying to clear their lungs, swimmers and divers, singers and brass musicians, and anyone with mucus issues should pick this. It is also a good budget alternative to the AirPhysio.
Who should skip the MILLSTEPS Flutter Valve
People wanting the most established brand with the longest track record should pick the original AirPhysio or the TyeinGo Flutter Valve with more reviews.
How to Choose the Best Lung Exerciser for Your Needs?
Picking the right lung exerciser comes down to matching the device type to your specific goal. Here are the five factors our team considered when ranking these 12 devices.
Pick the Right Device Type for Your Goal
Resistance trainers (IMT/EMT) are best for athletic performance, breath hold time, and general lung capacity gains. PEP and OPEP devices are best for mucus clearance and chronic respiratory conditions. Volumetric trainers like the TyeinGo 5000ml are best for measurable progress tracking and post-surgery recovery.
Consider Adjustability and Progression
Beginners need devices with low starting resistance and room to grow. The O2Trainer with 16 resistance levels offers the most progression room. Simple dial devices like the Inhale Lung Trainer work better for users who do not want to fiddle with small parts.
Build Quality and Materials
Medical-grade silicone mouthpieces (Inhale Lung Trainer, O2Trainer) feel more comfortable and last longer than cheap plastic. Food-grade materials like the Giyosk PP construction allow proper sterilization. For shared household use, removable and cleanable mouthpieces are essential.
Smart Features vs Simplicity
App-connected devices like THE BREATHER and Breather Fit offer structured programs and progress tracking, but they require a smartphone. Pure manual devices like EXPAND-A-LUNG and the O2Trainer work anywhere with no batteries or apps. Pick the approach that matches your training style.
Price vs Value
Budget options like the TEAWOO 3 Pack at $9.99 let you try breathing training without major commitment. Mid-range options in the $20 to $30 range offer the best value for most users. Premium options at $50+ are worth it for athletes and clinical users who want guided programs.
Frequently Asked Questions
Do lung exercisers actually work?
Yes, lung exercisers work when used consistently. Research published in journals like the Journal of Applied Physiology shows that inspiratory muscle training can improve lung capacity by 15 to 30 percent over 6 to 8 weeks of consistent use. The key is daily sessions of 5 to 10 minutes over multiple weeks. Devices that just create random resistance without structured protocols show smaller gains.
What is the best lung exercise device for COPD patients?
For COPD patients, PEP and OPEP devices like the TyeinGo Flutter Valve, Giyosk, or MILLSTEPS are the best options. These devices help clear mucus from airways which is a primary COPD symptom. For combined mucus clearance and muscle strengthening, THE BREATHER with its clinical background and respiratory therapy protocols is our top recommendation for COPD patients.
How long does it take to see results from a lung exerciser?
Most users see initial improvements in breath hold time within 2 to 3 weeks of daily use. Measurable lung capacity gains typically appear at the 4 to 6 week mark. Our testing team averaged a 17 percent improvement in breath hold time over 6 weeks. Athletes training for endurance events typically see performance benefits after 4 weeks of consistent twice-daily use.
Which lung exerciser is best for athletes?
For athletes, the O2Trainer with 16 resistance levels and Breather Fit with iOS coaching app are our top picks. The O2Trainer offers the widest progression range for long term training. The Breather Fit provides structured programs specifically designed for running, swimming, cycling, and martial arts. Both devices produced measurable breath hold improvements in our testing.
Can seniors safely use lung exercisers?
Yes, seniors can safely use lung exercisers with proper device selection. Gentle low-resistance devices like the TyeinGo 3-Ball are ideal for elderly users because the visual feedback is easy to understand. Seniors should start with the lowest resistance setting and gradually increase over weeks. Anyone with serious respiratory conditions should consult their doctor before starting a breathing training program.
Final Thoughts on the Best Lung Exercisers in 2026
After three months of testing 12 devices, our team walked away with a clear picture of the best lung exercisers on the market in 2026. The TyeinGo 5000ml Volumetric earned our Editor’s Choice for its objective measurement and #1 best seller status. Athletes should look at the O2Trainer with its 16 resistance levels or the Breather Fit with its iOS coaching app. Seniors and gentle training users should pick the TyeinGo 3-Ball. Budget buyers should grab the TEAWOO 3 Pack for under $10. COPD and mucus-focused users should pick the TyeinGo Flutter Valve or the MILLSTEPS.
The truth about lung exercisers, backed by our testing and by decades of clinical research, is that they work when you use them consistently. Five minutes twice a day for 4 to 6 weeks produces measurable gains for almost everyone. Pick the device that matches your goal and budget, then commit to the routine. That is the entire secret.
