Fitbox Method

Following a similar cardio-plus-strength-training model as Orange Theory and Barry’s Bootcamp, Fitbox Method aims to burn fat and build muscle during a fast-paced, 60-minute session. The reason you should try this one instead of the others is for the bonus stress relief—rather than sprinting to nowhere on the treadmill, cardio here consists of a 30-minute boxing session led by eager instructors who correct your form and yell “Dale!” to keep you motivated (this is Miami, after all). How do you tell whether your killer sweat-sesh is working? Snap a pre- and post-workout selfie at the photo booth out front for real-time results.
