Abstract: Described herein are techniques, devices, and systems for formulating, tracking, displaying, and using electrical muscle stimulation (EMS) intensity values that are meaningful and intuitive. Electrical impulses may be delivered via multiple electrodes of an EMS suit in accordance with pulse intensity settings, the pulse intensity settings comprising multiple channel intensity values associated with multiple channels. Each channel intensity value can be multiplied by a predefined number to generate displayable channel intensity values, and a global intensity value can be derived from the displayable channel intensity values. The global intensity value can be presented on a display, such as by presenting the global intensity value as a graphic overlaying media content featuring an instructor conducting a workout session.

Abstract: An intensity of fitness apparatus output can be customized for a user during a workout session. A user profile of the user may be accessed to determine a starting intensity value at which output is to be provided by the user's fitness apparatus. Based on this starting intensity value and on command data associated with a workout session, an intensity profile for the user may be determined (e.g., created), which is usable for controlling an intensity of the output of the fitness apparatus during the workout session. While media content featuring an instructor conducting the workout session is output on an output device, the user's device may send commands to the fitness apparatus to control the intensity of the output of the fitness apparatus in accordance with the starting intensity value and, subsequently, the intensity profile of the user.
