TRX® Certified Instructor

SilverSneakers® FLEX Instructor

Certified Personal Trainer

Certified Wellness Coach

Certified Group Fitness Instructor


Being active has benefited my life in so many ways and I love encouraging others to keep moving! I enjoy teaching classes and training individuals of all ages and fitness levels, but I get the most satisfaction from seeing individuals overcome their fears and self-doubts, and discover the unlimited physical, social and emotional benefits they reap when they stay in motion.  We are all stronger than we think!  When I’m not teaching classes or training, I enjoy spending time with my family, kayaking, biking, paddle boarding, and trying out all of the great restaurants in the Lowcountry!


Maggie Bader

Spinning® Instructor, Mad Dogg Athletics

TRX® Qualified Instructor


Exercise has always been an important part of my everyday life, and it’s also something I truly enjoy.  I began taking Spinning classes with my mom as a way to spend more time together, and we continue to do so now that I’m in college.  My favorite thing to do is lift weights, however Spinning and TRX have also become important parts of my workout routine.  I love the supportive group setting that Spinning provides, and TRX pushes me harder physically than anything else I do.  I have always enjoyed helping people, so I am extremely excited to use something I am passionate about to help others reach their fitness and life goals.

When she's not chasing down the next big arts story, you can find her practicing yoga on her porch — if her dogs allow for it — or at Urban Yoga downtown. She's an occasional runner with a knack for knowing what muscles you're gonna want to stretch after some intense cardio. When she's not working, or working out, you can find her hanging out at a local brewery with her fiance, or her partner in crime, her twin sister.
