The POWERbreathe K-Series is the world’s first series of intelligent digital breathing training devices.
The K4 with Breathe-Link software is for the elite training, testing and monitoring of individuals. Regular breathing training improves the way that you breathe, which can benefit sports performance and give you an edge over competitors.
Whether you’re preparing for a triathlon, part of a professional football team, or training your breathing is essential to improving your health, the K4 is ideal.
Benefits of breathing training with POWERbreathe IMT include:
Strengthen your diaphragm- Breathing training with the POWERbreathe K4 strengthens your diaphragm rather than your lungs. This is because your lungs are a pair of spongy, air-filled organs, and not muscle, and therefore cannot be strengthened.
Patented ‘intelligent tapering system’- The K-Series uses a patented and researched based ‘intelligent tapering system’ that matches the strength profile of your breathing muscles. This is the most effective way of training your breathing muscles, compared to conventional methods.
The K-Series devices feature an electronically controlled ‘tapered flow resistance’ that uses a computer-controlled rotary valve to create resistance to your in-breath. Therefore, resistance is not fixed at the same level throughout your breath (unlike a pressure threshold device). Because the device automatically reduces the resistance as you progress through your breath, matching the load to your declining muscle strength.
Use a wider range of breathing muscles- The tapered flow enables you to perform a longer inspiration and use a wider range of breathing muscles to achieve higher flow and higher tidal volumes for better results. It achieves this by automatically adapting to increases in your inspiratory muscle strength at the beginning of each training session. What this means is that the training load is highest at the start of your inhalation and then gradually decreases as your lungs fill with air.
Automatic setup- During the first two breaths of each training session there is no resistance and you should inhale as quickly and deeply as possible. It’s during these breaths that the K4 device measures your maximum breathing capability. Training load is then gradually introduced during breaths three and four until full loading is achieved for breath five and onwards. During these breaths, you will find it increasingly harder to inhale.
Monitor training progress- Training measurement results are displayed on the K4’s LCD screen when connected to the software, and live, breath-by-breath, when connected to the software. This, allows you to monitor training progress and optimise your training technique.
See results after 4-6 weeks- Consistently follow the training regime of 30 breaths, twice a day to feel less breathless during exertion in 4-6 weeks. This is scientifically proven. Learn more about how the POWERbreathe IMT device works in our guide.

Declaration of Conformity

I bought this device years ago. I remember what an impact it had on my running after just 3-4 weeks off daily usage.
Over the next months, I was not disciplined enough to keep it up consistently with the cleaning and everything so eventually it ended in my drawer.
Now I found the device again after 7-8 years. I started the daily training and I immediately feel a difference only after a few days. I do a lot of zone 2 training (power walk) and while it is great for longevity, this does not challenge breathing muscles much. Therefore I have added powerbreathe to my daily routine.
I can highly recommend this gem of a device. I do not understand why so few people use it considering the benefits. Maybe it is because you need to be very disciplined to have lasting benefits?

Thank you so much for your feedback – and well done on starting again and persevering. It’s great to hear how you feel you’ve made improvements already.

What is auto-optimising technology?
The K-Series automatically estimates your training load at the beginning of every training session. Using this method, the device will adjust the training load every time you start a new session and as the strength of your inspiratory muscles increases. Automatic setup of this load takes place during the first two breaths of each training session.
Have measurements been independently validated?
Can more than one person use the same device?
For hygiene reasons, we recommend that users do not share the same valve head and mouthpiece. However, additional additional valve heads with mouthpiece are available for all K-Series models.
Does my K-Series model ever need re-calibrating for maintaining accuracy?
It really varies based on the user e.g. trainer, private individual, as well as personal needs.
We offer a calibration service to meet the needs of the respective groups. Individuals may wish to have this service for peace of mind in the knowledge that their device is functioning correctly. However, due to calibration being a chargeable service, you may choose not to.
What is the Breathe-Link software compatibility?
NB: The K4 and K5 Breathe-Link software is NOT yet compatible with macOS Big Sur 11.01
Software is PC compatible (except for Windows 10 S for which it is not compatible). It is also MAC compatible, working on the following MAC OS. Mac software will only work for x86_64 bit architecture.
