The POWERbreathe K-Series features Auto-Optimising Inspiratory Muscle Training (IMT) that automatically adapts to your own personal training requirements.

Why is this beneficial?

When your lungs are empty, your muscles are at their strongest. As they fill up with air, they gradually lose strength. Physiologically, this is to stop you being able to over-inflate your lungs. If you put a strong resistance against the in-breath, you will only be able to exercise the inspiratory muscle for the first part of the breath. The POWERbreathe K-Series automatically changes the resistance/load, decreasing gradually to match the strength curve of the breathing muscles during an entire breath to maximise the training effect and results.

The POWERbreathe training regime of 30 breaths twice a day, typically takes only a few minutes a day, and when used correctly you should start to feel the benefits within just a few weeks.

POWERbreathe is drug-free and natural with no side effects or drug interactions.

  • Inspiratory muscle training (breathing muscle training), such as training with POWERbreathe, is not recommended for patients with a history of spontaneous pneumothorax (a collapsed lung that was not due to traumatic injury e.g. broken rib), as it may lead to a recurrence of the condition. Following a traumatic pneumothorax and/or broken rib, POWERbreathe should not be used prior to full recovery.
  • Inspiratory muscle training is not suitable for asthma patients who have low symptom perception and who suffer from frequent sever exacerbations. Inspiratory muscle training is not suitable for anyone who has recently experienced a perforated eardrum. Anyone who is under the age of 16 should only use POWERbreathe with supervision from an adult.
