Physical fitness is one of the key attributes of a good police officer. The job may require you to chase a suspect, forcefully apprehend a subject or defend yourself from an attacker. These occurrences do not happen every day, but you must be physically prepared for them. The job of a police officer can be very stressful. Stress can lead to several ailments including heart disease. Studies have shown that a body that is in good physical condition is better prepared to handle stress. Therefore, law enforcement agencies are looking for individuals who have developed a healthy and fit lifestyle.
