Critical components of every law enforcement agency are the health and wellness of individual officers. At a moment’s notice, an officer could be called into intense activity, a sustained chase, or significant physical output. These physical demands, paired with the difficult work schedules of officers, contribute to a need for condensed, yet effective, strategies for improving or maintaining fitness. One method that can meet this need is high-intensity interval training (HIIT), which provides officers with a realistic way to achieve significant health benefits without requiring them to dedicate multiple hours each day to a workout. The information provided herein will give officers a clearly defined concept of what HIIT is, the physiological and psychological benefits of HIIT, and samples of traditional and nontraditional HIIT training programs that they may be able to use.
