About Kimball Theoret


With over 20 years of experience in the fitness industry, Kimball brings a wealth of knowledge and a fresh perspective to her practice. She is dedicated to helping her clients accomplish their personal fitness goals.  Her focus is on education and strategizing to develop the best possible independent training.


Kimball’s training philosophy is founded on a strong belief in using cross training techniques for overall health benefits.  It includes a comprehensive training methodology. 


“I tell my clients to work out in all other areas of the gym, not just in cycling class every day or on an elliptical machine for an hour.  I want to see everyone mixing it up and challenging themselves in a variety of ways.”  


Committed to Helping You Achieve Your Fitness Goals

It is her dedication to pursuing excellence and providing innovative and creative, yet highly effective programs to cross train that led Kimball to create her own award-winning class formats.  These include:
CrosSpin, a class that combines indoor cycling and off the
bike circuit training

PT FreeSTYLE, a dynamic mix of interval cardio training, strength training, plyometrics, speed and agility and stretching

Ongoing development of effective and fun fitness programs
for individuals and groups including On Track, a treadmill
interval class

“I promote health and fitness as a lifetime commitment and investment you make in yourself.  While a lot of people think working out is just for aesthetic value, a healthy workout program can truly improve the quality of your life both emotionally and physically.  Nothing beats a program of plain dedication and hard work and the benefits are so worth it.”


Kimball holds multiple certifications in group exercise instruction, personal training and indoor cycling and taught group exercise classes for most of the major health club companies in the U.S.   She is the founder of Group Xtreme Training, a consulting company specializing in teaching group exercise instructors how to effectively communicate with students in order to facilitate maximum performance.    

Kimball is a Fitness Consultant and Custom Gym Designer,

Print and Fitness Infomercial Model and Stunt Actor

While involved in the acting industry, Kimball was introduced to stunt fighting by eight-time world kickboxing champion and fight coordinator, Benny “The Jet” Urquidez.  She has since gone on to land roles in Baywatch, Silk Stalkings, Pacific Blue, Skin, American Lion, Blunt Object, Shelter Island, Alias and many more. 


She trains in a variety of martial arts styles including Kickboxing, Jeet Kune Do, Arjukanpo, Ukidokan, and Wing Chun and recently shot a layout for Inside Kung-Fu magazine.  


“Commitment to your health and quality of life for the rest of your life is vital, but that doesn’t preclude your workouts from being fun!  Enjoy your training time and enjoy the benefits.  Be the very best you can be!”
