Anna Dill, CPT

Personal Trainer

Anna hasn’t always been the picture of health.  At the age of 12, she was classified as obese, weighing in at 162 pounds. Growing up as a “latch-key kid” in the 80’s, she would come home and watch television while drinking Kool-Aid and eating chips. In middle school she decided to change her habits and lose weight.  It first started with drinking one glass of water after school before working out.  This was either a work out video or literally running around the house doing jumping jacks, push-ups and sit ups. By high school graduation, she reached her goal weight. From these experiences, she decided to help others achieve their health and fitness goals.  After graduating Cum Laude from the University of North Carolina at Pembroke in Exercise Science, she obtained her ACSM Health Fitness Specialist certification and has been working in the fitness industry ever since. Her main goal is to motivate others to create healthy habits that will last a lifetime.  Contact Anna by emailing:
