Military worldwide have publicly shared online their exercise routes recorded through the fitness tracker Strava revealing the fitness sessions conducted inside or near military bases. This leak of information has happened because military personnel turned on their fitness Strara tracker while making exercises at the bases.

The app allows users to set up privacy zones, that are areas where the Straa tracker doesnt collect GPS info, but evidently the military personnel ignored it.”]
