Casey Clay

I am Health and fitness enthusiast with the passion to teach and coach others to live a healthy lifestyle too..

My love for fitness started after the birth of my twins 8 years ago. I was 60 pounds heavier and felt tired everyday. After my first marathon in 2006, I found a passion for running and with running came the passion to eat better and exercise. I have participated in 3 marathons along with several half marathons, 5k and 10k events..

I love Kaia Fit because it’s challenging and fun! No matter what your fitness level is, you are sure to get a great workout in. Every class is designed different, so you will never get bored. I love knowing that I will see familiar faces and that we will all push ourselves to workout harder.

Heather Bell

Fitness has always been part of my life, but more on the side of playing sports like soccer and volleyball .I had quit my activities and let myself go to raise children. A year and half ago I decided I needed a change and joined Kaia Fit. It was the best thing I could've done for myself because I'm mentally, emotionally, and physically stronger. Now I'm a certified Kaia Fit Coach ready to help you through your journey!

Tina Koepke

In May of 2013 I joined Kaia FIT Natomas as a client for its first BRIK session so I could get back into shape for running. What I found was a turbo charged group of women that encourage each other, strive to meet fitness/health goals, and seek to be the best version of themselves daily. So not only was I able to get back into running shape, I also ran my very first full marathon in December of 2013 surrounded by women that I have grown to love, support me unconditionally, and motivate me to be my best every day.

I have always enjoyed living an active lifestyle. As a high school student I was a member of the JV and Varsity Cross Country team which led me to being a part of the CSU Sacramento Crew Team my 1st year of college. My degree in Biological Sciences and work in the healthcare industry over the years has helped me continue a deep desire to pursue a healthy active lifestyle that I enjoy sharing with my husband and 4 children.

What I love about Kaia is that each woman is celebrated on the unique journey they are on. As a coach I love being able to share fitness and nutrition information to help them each meet their individual needs and goals where they are right now and continue on to adopt a healthy lifestyle going forward.

Christy McKinney

Christy is a Bay Area native and grew up with her mother and her younger brother. She played basketball, volleyball and was a cheerleader for most of her childhood which kept her active year-round, and also enjoyed outdoor adventures as a Girl Scout. As an adult however, she fell into an unhealthy exercise lifestyle and gained 50 lbs when she was pregnant with her son. She always dreamed of being fit as she tried desperately to shed the baby weight. One of her life’s goals was to become a runner and run a mile. She watched two girlfriends have great success with Kaia Fit in 2013. So, in January 2014 she bought a Groupon and began her own Kaia Fit journey. She was hooked and crushed her first BRIK loosing 16 lbs and lots of inches! Christy is passionate about health and wellness and carries this passion with her while she works as a Pharmacy Sales Rep.

She is now proud to say she has ran a 5K and is preparing to run on her first CIM Relay Team with her Kaia Fit Sisters. Becoming a Fitness Coach has been life changing and inspiring other women to live a life they always dreamed of is something she never expected to happen when she joined Kaia Fit. This journey has truly been a dream come true!

Karen Bartells - Run Coach

If you had asked me five years ago, never in my wildest dreams would I imagine that I would be able to introduce myself as a triathlete and runner! I was mildly active, but have never been an athlete by any stretch of the imagination. A college roommate asked if I wanted to join her for a sprint triathlon. I didn’t own a bike, couldn’t run a block, and was terrified to swim outside a pool. Yet for some reason I agreed, and my life has transformed. Since then, I’ve done many sprint triathlons, two half ironmans, and added running, mostly half marathons and working on my second full marathon. Adding Kaia workouts has completed the transformation, making me stronger and more confident than I ever could have imagined.

I am so excited to share this love of triathlons and running with all of you. If I can do it, anyone can! I want to encourage anyone who’s ever wanted to give it a shot to come out and give it a try. One step, one pedal, one lap at a time…see how far you’ll go!
