A system to optimize diaphragmatic breathing is disclosed. The system has a first sensor to measure breathing movement of a user's abdomen and output a signal related to the movement of the user's abdomen, a second sensor to measure breathing movement of the user's chest and output a signal related to the movement of the user's chest； and a control device communicatively coupled with the first sensor and the second sensor. The control device has one or more processors, a memory comprising set of program modules executable by one or more processors. an assessment module for receiving the signal from the first sensor and second sensor and converting the signals to a data input, and for comparing the data input to a predetermined data range representative of proper diaphragmatic breathing for the user and a communication interface for providing feedback based on the assessment modules comparison of the data input and the predetermined range so as to optimize the user's diaphragmatic breathing. A method for optimizing diaphragmatic breathing is also disclosed.
