Kelly Kelly, CrossFit Expert and Coach

Competitive Athlete, CF-L3 and FMS

A Bay Area native, Kelly grew up playing soccer and water polo and found CrossFit in 2010 after returning home from the University of Michigan. Her first year in the CrossFit world was humbling and taught her that human beings are only truly limited by their own expectations. After pursuing her CF-L1, CF-L2, CF-L3 and FMS certifications, Kelly's coaching career over the last ten years has spanned age groups and continents, from working with youth soccer and basketball teams, to running weightlifting and gymnastics courses in South Africa. She believes that a solid foundation, quality movement and commitment to continuous growth are the keys to building more resilient human beings. Kelly is also a competitive CrossFit athlete, competing in the 2011, 2012 and 2014 Nor-Cal Regionals with Team Lifeworx and as a individual at the CF Regionals in 2013. Upon finishing her individual year, she then competed alongside Phoenix Rising in South Africa in 2017, and at the California Regionals in 2018 with Team Diablo Moxie. She has been an individual competitor the last few years, with a 6th place finish at the Mid Atlantci CrossFit Challenge Semifinal in 2022. You can catch Kelly walking on the beach enjoying the sunshine with a strong cup of bullet proof coffee, daydreaming about traveling and puppies.

Tim Youmans

CrossFit Level 2 Trainer (CF-L2)

Tim has called Santa Cruz his home ever since he was a young man, fresh outta high school. He has a lifelong passion for sports, fitness and competition, but has to admit that the Dad-Bod had taken over after many years where other priorities had pushed fitness down the list somewhere below his Friday night slow-pitch softball league. That was until Tim walked into his first Crossfit workout in 2013. He went in thinking of how the workout was incorporating familiar routines and regimes he had used previously, and when he finished he thought of how challenging, yet rewarding it had been. Oh and that everyone should be doing this. That’s when the trainer said that the warm-up was over and it was time to start the real workout. Tim fully believes that his fitness journey has saved his life and is excited that he can use his passion to help others achieve their own fitness aspirations.

Tim earned his CrossFit Level 1 (CF-L1) trainer certificate in 2018 and his CrossFit Level 2 (CF-L2) trainer certificate in 2022. He is a black belt instructor in Shotokan, Tang Soo Do and Taekwondo Karate and has competed in international karate competitions. Always the weekend warrior, Tim runs Spartan races, sprint triathlons and has competed in multiple CrossFit competitions including his most recent 1st place finish at the 2022 Northern California Classic, a 1st place finish at both the 2018 NorCal Masters and 2019 Masters Clash, and a 2nd place finish at the 2019 Northern California Classic.. The Youmans CrossFit clan includes his wife of over 30 years, Kelley and his two adult ‘yutes’ Shannon and Christopher.
