A device for monitoring the breath of a user includes a tub containing a liquid for at least partially immersing the user in the liquid and a weight sensor positioned to sense weight information of the user while the user is at least partially immersed in the liquid. A controller is operably connected to the weight sensor to receive the weight information and is adapted to dynamically determine at least one of a respiratory phase of the user and a respiratory amplitude of the user using changes in the weight information over a period of time resulting from buoyancy changes of the user. The respiratory phase and/or the respiratory amplitude can be utilized to detect volitional breath commands, to detect pain thresholds of the user, to provide breath synchronized manipulations to the user, and to provide breath synchronized coaching signals to the user.
