Methods, systems, computer-readable media, and apparatuses for determining a sedentary state of a user are disclosed. The apparatuses can be fastened to the user and include sensors configured to detect movement of the user. The apparatuses can also include a circuit coupled to the sensors. The circuits may be configured to determine, using the sensors, whether the user is sedentary； and in response to determining that the user is sedentary, determine one or more physiological attributes of the user of the device.
