The POWERbreathe K3 is the top-of-the-range model and uses the same auto-optimising IMT technology as the K1 and K2 models, but includes additional features.

POWERbreathe K3 (top-of-the-range model):

For people who require a comprehensive breathing training program, complete with all three Breathing Modes (training options) as well as Testing and Monitoring, and who wish to visually chart their improvement over all training sessions, both current and previous.

How POWERbreathe works:


POWERbreathe kinetic is ideal for:

  • People experiencing breathing difficulties resulting from a medical condition, sedentary lifestyle or old age
  • Sports professionals, including coaches, therapists, athletes, recreational fitness and sports enthusiasts
  • Uniformed services – army, navy, air force, police, fire service
    Performers, including singers, actors, musicians, public speakers and teachers

    POWERbreathe kinetic is the 3rd generation of POWERbreathe Inspiratory Muscle Training series (breathing training) and the world’s first portable precision electronic inspiratory muscle training and monitoring system that delivers a superior performance. POWERbreathe kinetic is rechargeable and supplied with a recharging and display stand.

    The POWERbreathe kinetic uses the basic principles of resistance training. Just as you might use weights to strengthen your arm muscles, breathing in through POWERbreathe against the electronically controlled, rapid-response valve creates a resistance to inhalation – thereby increasing inspiratory muscle strength and endurance.

    The POWERbreathe K3 training resistance is specifically designed to match the dynamic changes in breathing muscle strength throughout your breath and can automatically adapt to increases in your inspiratory muscle strength at the beginning of each training session. Training measurement results are displayed on screen, allowing you to monitor training progress and to optimise your training technique.

    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.

    • Enhanced the ability to sustain forceful breathing (breathing does not become fatigued)
    • Training may affect the intrinsic laryngeal muscles which control the action of the larynx
    • Warms-up the breathing muscles prior to rehearsal or performance

    Health & Medical

    Who's it for?

is it for?

    POWERbreathe is a multifunctional training tool that has a wide use of applications for a wide range of people. Randomised controlled trials have shown the efficacy of POWERbreathe in populations as diverse as highly trained endurance athletes, as well as patients with COPD and asthma.

    POWERbreathe training is particularly helpful in the following contexts:

    • All sports, including sprint sports and high altitude sports and training
    • Treatment of breathlessness and exercise limitation due to illness, including respiratory, cardiovascular and neuromuscular, or simply due to advancing age
    • Core stability training for injury prevention and the management of low back pain, postural instability and neuromuscular rehabilitation
    • Physically demanding occupational situations where breathing demand is raised
    • Settings in which the rib cage is restricted by clothing or equipment, such as protective clothing ensembles worn by the uniformed services
    • Settings where loads are carried on the thorax, such as military rucksacks and army Bergens
    • Settings demanding manual handling and load carriage, whether in an office, factory, warehouse or retail environment
    • Settings where breathing apparatus is used (self-contained and filtration), such as woodworking and fire fighting
    • Performing artists, including singers / vocalists, actors and dancers as well as teachers and public speakers where deep breathing, breathing control and voice projection are required
    • Wind musicians who are required to take deeper breaths, control the breath and have the ability to sustain forceful breathing

    POWERbreathe is suitable for almost anyone and will cause no harmful side effects when used properly. Please read the following precautions to ensure that you use POWERbreathe safely and appropriately

    • Inspiratory muscle training (IMT), 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, IMT, such as POWERbreathe, should not be used prior to full recovery.
    • If you are suffering from a cold, sinusitis or respiratory tract infection, we advise that you do not use POWERbreathe until symptoms have disappeared.
    • Some users may experience slight ear discomfort when training with POWERbreathe, especially if they are recovering from a cold. This is caused by inadequate equalisation of pressure between the mouth and ears. If symptoms persist, please consult your doctor.
    • Whilst training with POWERbreathe you should feel resistance to inhaling but it should not be painful. If you should feel pain whilst using POWERbreathe, stop immediately and consult your doctor.
    • If you have any doubts about the suitability of POWERbreathe, or you have a medical condition, please consult your doctor.
    • Anyone who is under the age of 16 should only use POWERbreathe with supervision from an adult. POWERbreathe contains small parts and is not suitable for children under 3 years.
