Say hello to Catherine Hamilton, better known as Coach Cat! Cat has been a member with us for a little over 2 years, and she fit right in from the start. She’s spent the last 6 months honing her skills as a coach here at Monument, and she is officially on staff and on the schedule!

Fitness has been a part of Cat’s life since she was young. Born and raised in North Carolina, she learned weightlifting in high school, which is where she fell in love with showing herself how strong she could be. To date, she has run over 20 half marathons and 5 full marathons, and she is one of those sick people who actually enjoys running long distances every day. She’s also a wedding planner, having worked in the industry for a decade and owned her own business since 2019. She loves dogs, and works as a dog walker when she isn’t planning weddings, running many miles, winning all the challenges at Monument Fitness, or crushing workouts with her husband and fellow member Josh.

We are pumped to have Cat on the team. She is a great person and brings positive energy to every class she is a part of, but the best thing is how passionate she is about what we do and about fitness in general. In her words: I love CrossFit and the opportunity to cheer people on while they work on becoming the best and strongest versions of themselves. It truly gives me joy to help push people and be there when they realize their body and mind are capable of doing something harder than they thought they could.

Come see Cat on Saturdays and filling in during the week this Fall!
