Unlock the power of your breathing with the POWERbreathe expiratory muscle trainer.

Expiratory muscle training known as EMT or EMST, strengthens the muscles used for breathing out. These muscles are important for coughing, swallowing, voice and airway protection, in particular for people with Parkinson’s Disease, stroke rehabilitation and other neurodegenerative conditions. The POWERbreathe EX1 is a drug-free, hand-held device that trains your expiratory muscles to improve strength, reduce aspirations and support health and vocal performance.

Offering the widest range of resistance levels on the market, the POWERbreathe EX1 range of devices has been developed in conjunction with Speech and Language Therapists around the world. Our expiratory muscle trainer is a simple, comfortable and effective device to use every day. You can now upgrade and digitalise the EX1 with the POWERbreathe Smart Adaptor and ActiBreathe® App for real-time feedback, personalised breathing guidance, expiratory muscle strength testing and comprehensive analysis on your phone or tablet. The Smart Adaptor takes your EMST device and training to the next level, calculating an appropriate training level for your needs, and reminding you when its time to train.  

The POWERbreathe EX1 is easy to use and adjust. In a seated or standing position, hold the EMT device in an upright position; do not block the air inlet at the bottom. Place the mouthpiece in your mouth and breathe in fully. Once your lungs are full, breathe out through the device as fast and forceful as you can. Squeeze as much air out of your lungs as possible. Repeat the process again. You can remove the expiratory muscle trainer from your mouth during inhalation if you find it easier or more comfortable. As a guide, we recommended performing 5 exhalations, 5 times per day, for 5 days. After that time, review your resistance level as you may be able to increase the load.

How this EMST Device Works

The POWERbreathe EX1 expiratory muscle trainer uses a spring-loaded valve to create resistance as you breathe out, just like lifting weights for your breathing muscles. Using ‘Pressure Threshold’ technology, your breath must generate enough force to open (or lift) the valve and keep it open. As your muscles work harder against this resistance, they grow stronger. As your strength improves, gradually increase the challenge by turning the dial (levels 0–10) to increase the load.

What is POWERbreathe EMT ?

Training Diary

All it takes is:

  • 5 x 5 x 5 : Perform 5 forceful exhalations, 5 times a day, 5 days per week.
  • Progressive Training: Adjust resistance using the dial (levels 0–10) as your muscles strengthen
  • Track Progress: Keeping a record of the training level reached and the number of breaths successfully completed in each session will help you analyse your progress. Or connect to the ActiBreathe® App via the optional Smart Adaptor.

Training Protocol:

This targeted training approach avoids combining inspiratory and expiratory effort in a single breath, which research shows can limit effectiveness. By focusing purely on exhalation, the EX1 delivers comfortable and results-driven training.

Load Range

The POWERbreathe EX1 Range offers the largest resistance range of all known EMT / EMST devices on the market. Take a look at our Load Range Comparison Chart for a more detailed look at the different loads (or weights) each level provides for the different resistance models.

Please note: The Heavy resistance EMT device is only for those who have reached maximum loading on a medium resistance model. If you start with a heavy resistance model, you may struggle to achieve higher levels due to the faster progression between loads, your progress may be limited and your breathing technique could be compromised.

Precise load settings may vary due to: (1) the analogue nature of the calibrated spring tensioner and the precision with which the load is selected; (2) a small effect of expiratory flow rate upon spring compression such that high expiratory flow rates lead to greater spring compression, and a small increase in load.

This effect is common to all spring loaded devices, and its size is magnified by increasing spring range. It is also greater at lower absolute load settings.

FAQ

You can perform POWERbreathe Inspiratory Muscle Training (IMT) and POWERbreathe Expiratory Muscle Training (EMT) on the same day, but we recommend spacing the training sessions out rather than doing them one after the other.

POWERbreathe EX1 EMT devices are designed and manufactured in the UK and available in a series of 4 models, as opposed to one. Therefore we offer the widest range of training resistance loads on the market for an expiratory muscle training device.

Each model in the EX1 series offers ease of adjustment, as the clearly visible scale on the handle of the device indicates the training level set and therefore the expiratory load. There are 11 adjustable levels on each model, making it easy to tailor the training for everyone. 

Also, the ergonomic design of the EX1 is based on the established and bestselling design of the POWERbreathe Plus IMT device. This includes a soft comfortable mouthpiece. The design also makes it easy to hold without obstructing the air output and therefore training effect, and is comfortable to use.  

Most importantly, POWERbreathe EX1 EMT devices can be fully disassembled to ensure thorough cleaning, which is essential as they will be exposed to saliva.

The typical training protocol for expiratory muscle training is  5 x 5 x 5. This is five reps (exhalations), five sets per day (making 25 exhalations per day in total), five days per week.
Watch our video on how to perform the correct breathing technique with POWERbreathe EMT.

Yes, because your breathing muscles suffer the same ‘use-it-or-lose-it’ effect as your other muscles. So, if you stop your training for any length of time, your breathing muscles will begin to lose the strength and endurance that you have built up.

Expiratory muscle training with the POWERbreathe EX1 may feel uncomfortable but should not feel painful. You may experience a slight discomfort when training if you are recovering from a cold. This is caused by inadequate equalisation of pressure between the mouth and ears. If, however, you do find training painful, stop immediately and consult your doctor.

Yes, but it may exacerbate a cough. You must also ensure you clean the device thoroughly after each use. If you are suffering from a respiratory tract infection (which a cough may be a symptom of), we advise that you do not use your POWERbreathe EX1 EMT device until symptoms have disappeared. If in doubt, always consult your doctor.

The POWERbreathe EX1 is not suitable for children under 7 years of age as it contains small parts. Also, anyone who is under the age of 16 should only use the POWERbreathe EX1 EMT device with supervision from an adult.

Most likely because during inspiration you ‘actively’ use your inspiratory muscles to breathe in, primarily the diaphragm and external intercostals. Expiration is generally ‘passive’, because exhaling is brought about when your inspiratory muscles relax and air passively leaves your lungs.

However during heavy ‘exercise’ your expiratory muscles will play an active role in breathing. During forced expiration, when there’s a need to empty more air from the lungs than normal, the accessory muscles of your abdomen and the internal intercostals, contract, forcing the diaphragm upwards and pushing more air out.

Expiratory muscle training is not as widely studied as inspiratory muscle training, but the expiratory breathing muscles are likely to respond to the overload principle of resistance training, in the same way as inspiratory muscles and skeletal muscles.

No, because breathing against a load during exhalation makes it impossible to also work hard during inhalation, so your inspiratory muscles don’t get trained as effectively.

No. There is a strong argument for the use of expiratory and inspiratory muscle training to be performed independently of each other. This is because it is extremely difficult to train with maximal effort when both breathing phases are loaded at the same time.

During normal expiration, your lungs will start to deflate as your inspiratory muscles relax. However, during periods of active breathing, such as exercise or coughing, your expiratory muscles (internal intercostals, rectus abdominis, external and internal obliques, transversus abdominis) may contract to force air out of your lungs. Therefore, training your expiratory muscles will help to improve their strength and function.
