Fitness boot camps are a heart-pounding way to boost your fitness level. Boot camps are led by a fitness instructor and are based on the concept of military boot camps — intensive workout programs to get new recruits into shape, quickly. Fitness boot camps encourage camaraderie, and the group momentum helps participants get through fast-paced intervals of cardio, isometric training, strength training and endurance drills. Classes may range anywhere from 30 to 60 minutes, and usually meet multiple days per week. Boot camps often run a specific duration of time, say four to six weeks, which creates a team-like environment for class members. Other boot camps run year-round and students purchase package pricing for classes, similar to subscriptions that allow them a set amount of classes per week or per month.

Boot camps can be held indoors at a gym, outdoors in a park or on a beach, in a backyard — anywhere there’s room for running, jumping and sweating. Some instructors also provide DVD and online boot camps. You can also find boot camps tailored to your heart’s desire, such as bikini boot camp, or boot camps for new mothers. Boot camps offer an intense workout and are usually led by energetic instructors pushing you to do your best, but unlike military boot camp drill sergeants, fitness boot camp instructors typically don’t use intimidation or punishment to spur you on. Check with your doctor before starting a boot camp if you have health concerns, and always let your instructor know ahead of time if you have injuries.
