Resistance Cells are the independently adjustable controls that change the amount of resistance you use for your training with PowerLung model. This is why you can adjust your PowerLung model to achieve just the correct amount of resistance to train the muscles you use in breathing. The PowerLung User Instructions and video show you how to determine the best setting for your current level of breathing strength so you can build on it for improvement.
