The DUFF group class program created by Charleston personal trainer, Andrew Duffy is a unique workout that encompasses a wide variety of hybrid training methods. Unlike most small group training programs and boot camps, DUFF incorporates different fitness levels and modifications for every exercise. This helps to ensure you’ll see maximum results from your workouts in a safe manner without risking injury. Hands-on coaching is provided with particular attention to exercise form and technique.

Work at your own level and be motivated and pushed to provide your best effort by the top trainers in the Charleston area.

ALL FITNESS LEVELS ARE WELCOME!!  It doesn’t matter if you are brand new to exercise or have been “in the game” for years, all DUFF classes will challenge you for your particular and individual needs. 

No one class is ever the same!  This keeps the body guessing and in turn never hitting a plateau, which will without a doubt change the shape of your body!  DUFF takes our classes through different periodizations of focus every 4 weeks to make sure that the body never gets accustomed to the same type of training. DUFF boasts a huge 5,500 square foot facility in the heart of Mount Pleasant.  You name it, we got it!  Come and check us out!
