Advantage was life changing for me. I walked in winded from going up the stairs. Couldn't shrimp down the mat without stopping and resting. I was an utter disgrace and out of shape. The instructors were motivating. Within a few weeks I changed my diet and started quiting bad habits. I've averaged 10 lb a month in weight loss. I'm 3.5 months in and find myself jogging on off days to burn off energy. You get what you put in, but this place has a world class mat and the instructors give you the tools to succeed in your goals.
