Dr. Kellie Walters

Born and raised in Northern California, Kellie learned to value a healthy lifestyle from an early age. Her mother’s involvement in the fitness world and her own experience with athletics lead Kellie to pursue her Bachelor’s Degree in Kinesiology from San Diego State University (SDSU). After graduating from SDSU, Kellie obtained her Master’s Degree in Exercise Science from Colorado State University where she continued her professional career as the Director of Adult Fitness and Instructor in the Health and Exercise Science Department.  Kellie is an Assistant Professor in the Kinesiology Department at California State University, Long Beach. During her PhD, Kellie piloted Smart Fit Girls in Pendleton, SC and since then, the program has expanded to Colorado, California, and Wyoming. In addition to studying the impact of Smart Fit Girls, Kellie’s research focuses on the relationship between physical activity and psychosocial health in adolescent girls and their mothers.

Kellie currently lives in Costa Mesa, CA with her husband of 7 years. In her free time she enjoys teaching group fitness, traveling to visit her family, and spending time with her husband and furry kids.


Kellie & Chrissy met at Colorado State University while completing their Masters Degrees in the Department of Health and Exercise Science. They quickly became best friends, bonding over wellness, weight lifting and a shared passion for helping women to become the best versions of themselves. Kellie and Chrissy started an online for-profit wellness coaching business for women called Smart Fit Chicks. The more women they coached, the more they began to realize just how prevalent body image and self-esteem issues are. This sparked a conversation between them about why they weren’t intervening earlier. Out of this conversation, Smart Fit Girls was born. And as the saying goes, the rest is history.
