POWERbreathe Classic

Medium Resistance


Choose POWERbreathe Classic Medium Resistance:

  • If you exercise / are physcially active for more than 2.5 hours per week and have no breathing problems
  • If you exercise / are physcially active for more than 2.5 hours per week and have some breathing problems

POWERbreathe Classic (Medium Resistance) uses a variable load calibrated spring, calibrated to a Medium Resistance. It can be adjusted from the lowest load setting (10cmH2O) when you begin training and increased as your breathing muscles adapt and become stronger (maximum load setting 170cmH2O).

REF: PB1002


  • First generation POWERbreathe Inspiratory Muscle Training (IMT) device
  • Mechanical, adjustable with load setting indicator
  • Drug-free - no side effects or drug interactions
  • Awarded a Millennium Product by UK Design Council
  • Washable

Medium Resistance Load Settings

  • Level 1 = 10cmH2
  • Level 2 = 30cmH2O
  • Level 3 = 50cmH2O
  • Level 4 = 70cmH2O
  • Level 5 = 90cmH2O
  • Level 6 = 110cmH2O
  • Level 7 = 130cmH2O
  • Level 8 = 150cmH2O
  • Level 9 = 170cmH2O

Precise load settings may vary due to: (1) the analogue nature of the calibrated spring tensioner and the precision with which the load is selected; (2) a small effect of inspiratory flow rate upon spring compression such that high inspiratory flow rates lead to greater spring compression, and a small increase in load.

This effect is common to all spring loaded devices, and its size is magnified by increasing spring range (it is larger in a spring with a maximum range of 90cmH2O compared with one with half this range), it is also greater at lower absolute load settings.

POWERbreathe is a scientifically proven Inspiratory Muscle Training (IMT) device, developed by leading scientists for improving the strength and endurance of the muscles used to breathe in, primarily the diaphragm and intercostals / rib cage muscles.

As with any other muscle, respiratory muscles can be trained so that they are more resistant to fatigue. This resistance to fatigue results in reduced breathlessness and enhanced exericse tolerance. 

POWERbreathe Classic uses scientifically proven Pressure Threshold Training. This provides a specific and consistent pressure to train against. When breathing in through POWERbreathe the load calibrated spring provides the resistance.  

How to use:

  1. Put the nose-clip on so that it pushes your nostrils together (this is optional but prevents you from breathing in through your nose).
  2. Breathe in quickly and forcefully through your POWERbreathe for 30 breaths twice a day (preferably morning and night so you allow your inspiratory muscles time to recover in between sessions). This is the scientifially proven training regimen.
  3. As your inspiratory muscle strength and stamina improve, adjust and increase the resistance.
  4. Within a few days your inspiratory muscles will feel stronger; within 3-weeks you’ll feel less breathless; and within 4 weeks activities will feel easier.
  5. Full instructions are provided in the accompanying user manual.


  1. Your POWERbreathe will be exposed to saliva during use. We recommend that a few times a week your POWERbreathe should be soaked in warm water for about 10 minutes (see your POWERbreathe Manual for full details).
  2. Once a week your POWERbreathe should be soaked in a mild cleansing solution instead of water, using the POWERbreathe Cleansing Tablets - only 1 tablet is required each time. 

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

If you have any doubts about POWERbreathe’s suitability, or you have a medical condition, please consult your doctor.


  • Do not make changes to any prescribed medication or prescribed treatment programme without consulting your doctor.
  • Do not use POWERbreathe if you are suffering from a ruptured eardrum.
  • To prevent the potential transmission of infections, we recommend that you do not share your POWERbreathe with other users, including family members.
  • This product is not intended to diagnose, treat, cure or prevent any disease.
  • POWERbreathe is designed for exercising your inspiratory muscles only. No other use is intended or implied.
  • 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 7 years.
  • Whilst training with POWERbreathe you should feel resistance when inhaling but it should not be painful. If you should feel pain whilst using POWERbreathe, stop immediately and consult your doctor.
  • Some users may experience slight ear discomfort when training with Medic Plus, 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.
  • If you are suffering from a cold, sinusitis or respiratory tract infection, we advise that you do not use POWERbreathe until symptoms have disappeared. If in doubt, consult your doctor.
  • Refer to your Healthcare Professional before using POWERbreathe if you have any of the following conditions:
  1. 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.
  2. Pulmonary hypertension o Large bullae on chest x-ray
  3. Marked osteoporosis with history of rib fractures
  4. Desaturation during or following IMT (<94%)


Inspiratory muscle training, such as training with POWERbreathe, is not recommended for patients with certain conditions, including the following:

  • Asthma patients who have low symptom perception and suffer from frequent, severe exacerbations or with an abnormally low perception of dyspnoea
  • If you are suffering from a ruptured eardrum or any other condition of the ear
  • Patients with marked elevated left ventricular end-diastolic volume and pressure
  • Patients with worsening heart failure signs and symptoms after RMT / IMT
  • If in doubt, consult your Healthcare Professional.
  • POWERbreathe IMT device
  • Mouthpiece (PVC - not made with natural rubber latex or and phthalates)

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.
Very Sceptical at first, now I must admit I can see improvements

I was very sceptical of this device when I was first recommended it, as there are a lot of devices out there that make all sorts of fantastic claims to aid your breathing at Altitude. This is one of them that now has a growing voice from well respected high altitude mountaineers, along with having been used by numerous Everest expedition climbers and also has nearly a full page dedicated to it in the fantastic book "Mountaineering Training and preparation" a book which I can most certainly highly recommend for your training....

...It just seems such a simple device to use that it is hard to believe that it can be this alone that is making these huge improvements in my breathing, but without a doubt I have only noticed these improvements since using the PowerBreathe.

Life resumes, without the need for health damaging Antacids, PPIs & H2 blockers
Review by D Lewis

After food had been jamming in the lower part of my oesophagus, an endoscopy had revealed a minor Hiatus Hernia. After doing my own Internet research, I decided that I needed to strengthen and bulk up my Diaphragm. After having experienced the misery of Acid Reflux for several weeks, I have found that the regular use of a blue “POWERbreathe” for a couple of weeks appears to have effected a complete cure. Normal life resumes, without the need for health damaging Antacids, PPIs & H2 blockers.

Review by Powerbreathe, along with regular exercise has obviously reaped rewards
Posted 20 September 2012
I have used the Fitness (Blue) POWERbreathe for around 4 years, maybe more, it was purchased as a Father’s Day present to supplement cycling and martial arts within my efforts to keep fit. The POWERbreathe is used daily and during a recent check up at the doctor’s, as l turned 50 last November, they stated that my overall breathing/lung/chest area were very good and when questioned on my exercise regime l mentioned the use of the POWERbreathe and was advised that the combination of its use along with regular exercise had obviously reaped rewards.

Taekwon-do stamina

I have been using Powerbreathe for the last three years alongside regular training. As a fifty seven year-old instructor I find that I can continue sparring in many cases longer than many of my much younger practitioners. I still suffer from aching muscles etc but rarely run out of breath. It compliments my training.
