CobraFit

For the trainers behind CobraFit, exercise alone isn't enough: even the best workout will get clients only part of the way to the body they want. That's why they include energy drinks and recovery shakes to maximize the results of each workout. Their high-intensity resistance-training sessions are designed to simultaneously burn fat and build lean muscle in just 30 minutes, which flies by as instructors blast upbeat music and students burn up to 500 calories after each workout. CobraFit also provides complimentary body profiles that help reveal how quickly the metabolism runs, how the body is aging, and how simple lifestyle adjustments can enhance overall fitness.
