Ryan Young coach at 720 Athletics

Ryan Young

Head Coach/Manager

Ryan started his CrossFit journey in 2015 after he finished his collegiate tennis career. He was instantly hooked after the first workout and never looked back. Ryan began coaching a few months later and has been involved with CrossFit ever since. He served as the head coach of his local gym in Mississippi before moving to Denver with his wife in 2020. Ryan obtained his Bachelor’s degree in Exercise Science at Mississippi State University. He then went on to get his Master’s degree in Exercise Physiology while interning as a strength and conditioning coach for the Olympic sports program at Mississippi State. He always knew he wanted to pursue a career in coaching. He has coached at several gyms in the Denver area but fell in love with the community at 720 Athletics. CrossFit Level 2 Certified

Griffing Zigrang coach at 720 Athletics

Griffin Zigrang

CrossFit Coach

Griffin was introduced to CrossFit in 2011 when she stumbled upon crossfit.com and started doing the WODs at her local globo gym. She was immediately hooked. After moving to CO in 2014, she joined her first affiliate at CrossFit Ken Caryl, and a few months later, she found her place at 720 Athletics. Griffin was a gymnast from the time she could toddle until she was a 14-year old Level 9/10. She was forced to quit due to scoliosis and the inevitable spinal fusion surgery. After surgery, she moved on to power tumbling, competitive cheerleading, and competitive dance, but gymnastics was a passion that, years later, she still hasn’t gotten over. You will see evidence of this in her classes as she focuses on movement, proper body positions, and strict strength. Pre-CrossFit, Griffin earned her Bachelor of Science in Psychology from Longwood University and Master of Art in Organizational Behavior and Program Evaluation from Claremont Graduate University. She did program evaluation work in the public sector, both at the federal and local levels, for six years before acknowledging that the fitness world was where she needed to be.

She began her coaching career in Pittsburgh in 2019 after recognizing the joy she felt in seeing others get better and succeed. In 2021 she moved to Colorado and was delighted to have the opportunity to continue sharing her passion for fitness with the 720 Athletics community as a coach. She has a particular affinity for learning and teaching the techniques of the Olympic Lifts.” CrossFit Level 1 Certified

Savannah coach at 720 Athletics

Savannah (Sav) Fearns

CrossFit Coach

Savannah found CrossFit in 2012 while attempting to shake off some weight. Having grown up playing soccer, swimming, snowboarding, and being raised in the military, physical activity has always been necessary. But even after joining the military herself, she still managed to fall into a funk. She dropped the weight yet felt weak until she found a group of CrossFit-inspired friends at the base gym. This gave her a new respect for strength and weight gain, and from there, she took it by storm. Realizing the iron therapy’s liberating effect on her life and many others, she proceeded to get her Level 1 in 2014 and could only hope to share the same joy that she’s had with her newfound health. Since then, she has coached at five gyms over two states and regularly entered CrossFit and Weightlifting competitions. CrossFit Level 2 Certified

She fell in love with the strength and confidence that CrossFit gave her. After taking some time off to pursue bodybuilding – CrossFit called her back in 2021. Despite not having a background in sports or fitness – it didn’t take long for Tracy to fall in love with the way movement made her. In 2020, Tracy finally decided to make the jump and pursue a career in the health and wellness industry. Since then she has worked at several gyms in North Carolina and Colorado coaching people through nutrition, personal training, and group classes.
