Ethon Burns

Lead Trainer

Ethon has been a personal trainer for over 20 years, beginning with his days assistant coaching the Iowa Hawkeye TaeKwonDo team to nationals and coaching Junior Olympic TaeKwonDo camps, to owning personal training studios in the Chicagoland area, to coming back home to bring the culmination of his training experiences to the Iowa City Corridor.

Ethon specializes in functional movement so that all his clients become not only stronger and more powerful, but also move better and feel their best. Ethon strives to bring the latest training protocols and fitness knowledge to his people, including in the realms of olympic and power lifting, functional bodybuilding, Crossfit, sports-specific training, mobility, and, most currently, Gym Jones and Onnit philosophy and practices. He has a degree from The University of Iowa in sports psychology, with minors in exercise physiology, nutrition, and kinesiology.

He is also a Certified Onnit Academy Foundations Trainer and Onnit Academy Battle Ropes Specialist.

Sarah Harkness

Lead Trainer, Health Coach, Women's Programming

Sarah's fitness journey began much later in life. When she joined the faculty of The University of Iowa in 2011, she knew she needed to take better care of herself physically and mentally, and so she joined a local Crossfit gym. From there her interests in training have expanded to reaching the body's fullest potential. This journey has led to her becoming ProjectsMethod Certified, earning a Gym Jones Level 1 certification at their first Women's Only seminar, as well as a Gym Jones Level 2 certification. 


Sarah focuses on nutrition, meal prep, women's training and diet, and the social psychology of training (to compliment her PhD). 

Lauren French

Assistant Trainer

Lauren is an NASM Certified Personal Trainer and Weight Loss Specialist with a bachelor’s degree in Health Studies from the University of Iowa. She got her start in the weight room while on the Division 1 rowing team at Iowa. She was inspired by her coaches to become a personal trainer and group exercise instructor. Her background in exercise and nutrition turned into a passion for bodybuilding and weight loss. Lauren's experience as a rower, bodybuilder and NPC Figure competitor has molded her philosophy of training. That is to train for both functionality and aesthetics while maintaining a balanced lifestyle. 

Lauren is currently competing in Power Lifting, earning gold in multiple competitions.
