Fitness boot camp

A fitness boot camp is a type of group physical training program that may be conducted by gyms, personal trainers or other organizations. These programs are designed to build strength and fitness through a variety of types of exercise. The activities and format may be loosely modeled on aspects of fitness training used in the military and the trainers themselves may be former military personnel.

Indoor and outdoor boot camp workouts became popular in the United States in the late 1990s. Fitness boot camps as outdoor group fitness classes grew in popularity in the 2000s. These originated independently in Australia, the United States, the United Kingdom, and Canada.
