Patent attributes
Methods for instructing a user to perform head and neck exercises with head and neck apparatuses are disclosed. The apparatus may include a member operatively arranged with a valve mechanism with a threshold pressure. The apparatus may further include an acoustic apparatus, membrane, chromogenic material, or moveable element that may be configured to respond when the pressure within the member is greater in magnitude than the threshold pressure. The head and neck exercise apparatus may also include a member operatively arranged with an acoustic apparatus, membrane, chromogenic material, or moveable element that may be configured, without a valve mechanism, to respond when the absolute pressure within the member is greater in magnitude than a threshold absolute pressure.
