Bootcamp workouts can vary but generally include a fairly intense mix of strength training and aerobic elements. One bootcamp workout might stress calisthenics while another stresses military-style drills. Some even incorporate martial arts moves. In pretty much all cases, however, you can expect to do calisthenics, such as pullups, pushups, lunges and crunches, as well as drills and sprints. In essence, a boot camp workout is a type of interval training — bursts of intense activity alternated with intervals of lighter activity.
