    Since my last review in 2012 I have used the power breathe on a regular basis. I recently traveled to the Himalayas on a motor cycle (Royal Enfield) adventure to the worlds Highest motor able pass- Khadung-La.I had no breathing problems, it works. I still practice and teach Taekwon-Do on a regular basis.

    The benefits of training the lungs in this way is immeasurable
    When I informed my consultants/doctors that I had purchased one they were pleased and spoke of the benefits of using it. However, they did not offer to prescribe. There needs to be a bigger campaign to bring Powerbreathe equipment and training to the health industry. My awareness of it was only because of my involvement in the fitness industry. The benefits of training the lungs in this way is immeasurable! I have found excellent results and recommend it to anyone who has breathing difficulties or those who wish to increase their lung capacity for sport or fitness. Let’s get Powerbreathe equipment/training recognised and widely available in treatment plans for people who struggle to breathe!!

    I’m not sure. I feel worse after using the Powerbreathe or any breathing gadget and I don’t know why.

      Hi Barbara and thank you for your message. Would you like to send an email to enquiries@powerbreathe.com letting them know which POWERbreathe IMT device you have and how you feel after using it and they should be able to advise you. It may simply be that you’re training too hard, on a higher load than your breathing muscles are able to cope with at the moment. But it’s better if there’s a conversation and with email it can be done with more privacy for you. Hope that helps. Thank you.

Centimeters of Water is a unit used to measure pressure on a small scale. It refers to how much pressure is needed to move a 1cm column of water.

If required, there is a much more technical explanation available here:

There are no safety reasons for preventing young children (above 7 years of age) from using POWERbreathe. However, the following factors may affect their ability to use the device effectively: 

  • They must be able to fit the mouthpiece in their mouth. The POWERbreathe Plus mouthpiece is smaller and therefore more suited to children. 
  • They must be old enough to understand how to effectively perform the breathing exercises. 
  • They must have the motivation themselves or the parental encouragement to ensure that they continue to perform the exercises. 
  • They should only use POWERbreathe under the supervision of an adult.

Inspiratory muscle training has been most widely used in patients with COPD. IMT is particularly helpful in this patient group, as they have primary weakness of their inspiratory muscles.
