Can the breather fit be used like the breather voice?
That is a great question and the answer is, YES, IT CAN!
They are mechanically the same device and provide the same levels of resistance. The only thing that differentiates them is the resources we offer for each of them (videos, training plans, etc..), but you can access all of the resources easily, either on our webpage or on our Breather Coach App. If you are a Breather Coach App user, you can change the device you use to train on the "My Info" tab. Simply go there, choose a new device (fit or voice), and start a new training program!
If you go to our product pages on our site, you will find dedicated resources for each device.
