Kristen White - Owner


I joined the Fitness Industry in 2004 when I started teaching group classes.  I played sports throughout my childhood and high school years and have always loved being active.  Now I  enjoy running, cycling, strength and HIIT training.  If it challenges me, I typically get addicted.  I love getting to work with others and watch them evolve into something they never knew was possible... in terms of health, self confidence, and strength.  Most of my clients turn into life long friends, because we push, learn, laugh and sometimes even cry together.  It's a process, but worth it! 

Briamst Castro- Trainer/Coach


I was born in Honduras, but Tennessee has been my home since the age of 13. I played varsity soccer at Union University and earned a Bachelor of Science degree with an emphasis in Exercise Science. I am passionate about teaching proper technique and application of basics to advanced movements of strength and conditioning. Whether you’re aspiring to be a collegiate athlete, dreaming of being a professional athlete or working toward moving well in daily activities, I will develop a program that will work best for your needs. I love to play soccer on the weekends and watch soccer on TV. One of my favorite quotes is "My mission in life is not merely to survive, but to thrive; and to do so with some passion, some compassion, some humor, and some style." -Maya Angelou-  

Anna English- Instructor


Working out has always been one of my favorite stress reducers. I instantly feel in love with group classes in college because of the encouragement. I love coaching and watching people give their best.  The "group effect" is proven to help you maintain your motivation through support and inspiration.  The students inspire me and I get the privilege to push them to do their best."
