chris
Coach
CrossFit L1
CrossFit L2BS Exercise Science
Nutrition MinorChris has been doing CrossFit for 9 years and coaching for 7 of them. He grew up being a very active individual and my passion for sports and movement was always there, but he seemed to have lost that over the years - until he walked into his first CrossFit gym.
He was challenged not just physically, but mentally and emotionally and soon after, he fell in love with the community and the changes that were taking place to his body, and my mind.In his free time he plays a lot of golf. He’s always down for a good sweat and LOVES jumping into class workouts with the community. Human movement is a big part of his life and through his participation and coaching in CrossFit that he has had throughout the years, it has given him many opportunities. He’s convinced that how we do anything is how we do everything – and it’s his great pleasure to instill that in my members every single day, doing what he loves
Kim
Coach
CrossFit L1
RRCA certified running coach
Kim is excited to join the Rxfit family and has brought with her an enthusiastic passion for life long fitness. She began her fitness journey after the birth of her last child, with an invitation from a friend to run a few miles with him.
With that invitation, she continued to progress and eventually began to train and has since run multiple marathons and half marathons. Looking for a change, she stepped into a Crossfit gym where she picked up a barbell for the first time at the age of 40. She found a community of dedicated athletes no matter if they were new or seasoned. She is also the director of The Launch Team, a not for profit youth organization that trains and prepares youth to complete half marathons.She has 5 glorious daughters and a darling husband who she says is the best cheerleader a girl could ask for.
