It helps increase your breath volume so you can breathe more easily and not depend on your neck back and chest muscles to breathe. Finally, it helps make you aware of how you are breathing. It is suggested that you practice with the exerciser twice a day for the next six weeks.

In my private practice the most frequently borrowed piece of equipment, and the most difficult to get returned, was the MotivAider. You will also love it. You clip this small device, the size of a small pager, on your belt or in a pocket against your body. It gently vibrates to remind you to be aware of your breathing during busy work days. No one knows but you.
