Everyone is different and everyone has different needs and goals. In order to provide products that will benefit the widest range of users, we have created different levels of PowerLung. This allows us to provide a model for users who only need to breathe better during daily activity, and a model for the professional athlete who wants to train their breathing to the highest level. And it allows you to select the model that best fits your needs and goals and best meets your current ability but still allows for the improvement you want to achieve.
You can choose the model to meet your goals not just try to adapt one size to meet part of your goals.
