The Denton Police Department does not currently have a physical agility test such as an obstacle course or a Cooper test. Much later in the process, candidates are sent to a physician for a physical exam and stress test. Candidates will be subjected to physical activity in which their heart will be monitored. The doctor will make a determination on whether or not the candidate is fit for police work.
If you are worried about the physical assessment, see your doctor first and then consider starting your own health and fitness program.
