Yoonmee Hampson, CrossFit Level 2 Trainer (CF-L2), NASM Certified Personal Trainer, CrossFit Mobility Trainer, CrossFit Scaling Certificate

Growing up as a former benchwarmer on the soccer team and a rather pokey sprinter in high school track, Yoonmee initially wrote off CrossFit as “not for me.” But her curiosity got the best of her, and in 2011 she dove right into the deep end by getting her CrossFit Level 1 Trainer certification before she even joined a gym. She trained on her own for a while, but it wasn’t until 2012 when she finally joined a CrossFit gym and experienced firsthand the amazing, supportive, and friendly CrossFit community that she fell in love. Coaching since 2013, her mission is to help people to become the best version of themselves both in and out of the gym by delivering a positive, challenging, and fun experience through appropriate and effective programming encompassing fitness, nutrition, and community.

Yoonmee’s favorite CrossFit wod is CrossFit Disco. She loves hang cleans and pistols, but dislikes wallballs. She excels at introducing new members to CrossFit movements and helping women through their lifetime fitness journeys. She loves reading good books, the beach, coffee shops, and Korean food.
