The D.U.F.F. 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, D.U.F.F. 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!  D.U.F.F. 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!


Kids DUFF is our youth program here at Duffy’s Ultimate Functional Fitness in Mount Pleasant, SC.  Our youth is our future, and we at DUFF believe that the health and wellness of our younger generation is one of the most important aspects in our field.  Our Teen DUFF classes were developed to encourage, promote, and teach a general healthy lifestyle for kids.  With the Charleston schools cutting back on physical education these days, it is more important than ever to make sure that our younger aged individuals don’t miss out on a healthier lifestyle.

Teen DUFF is structured for boys and girls ages 7 to 12.  Ages 13 and up are ready for regular DUFF class unless they would like to try out our kids class!  We cover several different aspects in our Kids program including (but not limited to) the teachings of correct exercise form and technique, how to be functionally sound within everyday human and athletic movement, becoming faster, stronger, and more agile, as well as proper nutrition. Each Kids class is very different.  Some days we will focus on more bodyweight style movements, other days may have a little bit more cardiovascular exercises.  We also work on strength movements but in a safe manner without a lot of external weights.  Other classes may incorporate some sports influenced exercises such as jumping, hand-eye-coordination, and agility work.  We even introduce some gymnastic style movements which will get our teens ready for anything! Our classes here at DUFF, for our teens, are not just for athletes.  Every teen in the Charleston area is welcome, and nobody will ever feel left behind.  Our instructors are very hands on with each child as if they are getting a one on one personal training session within a group environment.
