The trainers at TNT Bootcamp make failure a near impossibility by demanding discipline and commitment from each of their charges. Though their words are kind and demeanors are friendlier than that of a teddy bear with a hospitality degree, the instructors of the intense four-week boot-camp program ensure campers adhere to a regimen of weekly weigh-ins, participate in a minimum of three weekly workouts, and maintain a food journal. Any lapse in duties or weight gain incurs a penalty, which TNT Bootcamp has found keeps participants on track even after they reach their goal weight. By completely remolding eating and exercising habits through boot camp and nutritional counseling, trainers help their pupils shed as much as 5 pounds a week. For attendees more interested in recreational exercise, the Just 4 the Health of It program waives penalties. Exercisers can also tone up in classes such as Zumba and the weekly Saturday Sweatshop, which keeps already fit frames in shape and ready to run away from bears at all times.
