The POWERbreathe® K-Series uses electronic variable threshold resistance training to provide a tapered load that will match the contraction curve of your own breathing muscles throughout your entire breath. This enables you to complete a full breath and muscular contraction at the most optimal resistance for you. In other words, the K-Series does everything for you, so there is no guesswork as to where you should start. It guides you. It is your coach.

Your age, weight, height and gender when entered into your K-Series device help to build up your personal profile. The K series uses this data to estimate your predicted inspiratory muscle strength, the calculation for which is based upon scientific research that investigated the force-velocity characteristics of the inspiratory muscles.
