The POWERbreathe EX1-HR Expiratory Muscle Training (EMT) device is the most challenging of all our EMT devices. It exercises your expiratory muscles at an advanced level to improve your expiratory muscle strength and endurance.

The POWERbreathe EX1-HR offers the heaviest of resistances and is only suitable for those with large lung volumes, and who have reached the highest level on the POWERbreathe EX1-MR device.

It is a light, hand-held and easy to use drug-free breathing training device. It targets your expiratory muscles and exercises them using the principles of resistance training to increase your expiratory strength and endurance.

The POWERbreathe EX1 is a hand-held, drug-free, expiratory muscle training (EMT) device, developed to improve your expiratory muscles’ strength, function, and endurance. It provides resistance as you breathe out through the device, making your expiratory muscles work harder to improve breathing strength.

The POWERbreathe EX1 uses the ‘pressure threshold’ method of breathing training, which is like weightlifting. You progressively adjust the ‘weight’ lifted to make your training harder (or easier) as your expiratory muscles become stronger.

The typical training protocol for expiratory muscle training is 25 breaths, made up of  5 x exhales, 5 times a day (for 5 days a week) = 5 x 5 x 5.
