Though the term ?boot camp? may conjure images of aggressive drill sergeants barking orders as their recruits struggle through grueling tasks, JM Fitness sessions are much the opposite. Their enthusiastic trainers motivate patrons in indoor boot-camp classes, issuing positive reinforcement as they work together to burn calories and excess fat through challenging, but not defeating, exercises. Each 35 minute session is designed to promote fat loss with a varied routine of interval training that may involve weightlifting, push-ups, sit-ups, and plyometrics. Many activities require participants to band together to tackle obstacles, bolstering a sense of support and camaraderie. Instructors then lead exercisers in a cool down with stretching, leaving them more limber than a linguini noodle basking in a Jacuzzi.
