Systems and methods are provided for tracking, collecting, or analyzing user data for gyms. For example, the system can include a mobile device associated with a user and a tracking device attached to an exercise device. The tracking device can be configured to detect when the mobile device or the user enters within a proximity value of the tracking device and notify the mobile device with a notification signal and identification information of the exercise device. The mobile device can be configured to receive the notification signal from the tracking device, detect a received signal strength (RSS) of the notification signal, and determine whether the RSS is above or at a pre-determined threshold. When the RSS is above or at the pre-determined threshold, the mobile device records the identification information of the exercise device. When the RSS is below the pre-determined threshold, the mobile device ignores the notification signal.
