K3 Blue


The POWERbreathe K3 is a hand held, electronic inspiratory muscle training device that offers you an advanced level of breathing training, without any software to deal with.

In addition to the features of the K2, the K3 also includes additional training modes for warming-up your breathing muscles and a cool-down or ‘recovery’ after exercise.

The K3 stores data of your previous 36 training sessions.

The POWERbreathe K-Series is the world’s first range of intelligent digital breathing training devices.

The K-Series uses a patented and researched based ‘intelligent tapering system’ that matches the strength profile of your breathing muscles, providing you with 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 the resistance to your in-breath. As a result of this, 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.

The tapered flow enables you to perform a longer inspiration and use a wider range of breathing muscles so you 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.

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 K-Series 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.

Training measurement results are displayed on the device’s LCD screen, allowing you to monitor training progress and optimise your training technique.
