FitGuana is a High Performance Hybrid Athletic Club.  We do things very differently than the average gym as we fill the void between the minimalistic warehouse gyms and the upscale machine rich fitness centers.  We are focussed on high performance, health and optimizing your body by using a holistic approach to fitness, nutrition, recovery, supplementation and much more.

Our 3,800 square feet high end facility has everything you need to push your limits yet work within your own abilities.

The goal at FitGuana is to create an environment which motivates you to improve your lifestyle and fitness choices.  Therefore, we have established a facility which enables all levels to challenge themselves.  Novices as well as established athletes are able to join a class and safely work at both their strengths and weaknesses.

A wide variety of equipment and training methods are available and used to provide you with innovative, highly efficient and most importantly FUN sessions.  Focus and passion are at the core of every session so you can make continuous progress.  Fitness is not a destination, it is a journey and we never want you to stop improving.

As you will see, our facility was designed with detail in mind.  Equipment was carefully chosen and cleanliness is our priority.  Towels, filtered water and even extra pony tail bands are available to offer you the best experience.  Two new spacious ADA bathrooms and shower are available for your use.  

To offer you the best training experience, FitGuana is a MyZone facility.  This enables you to track your progress, fitness as well as join challenges and earn rewards.

Owner / Head Coach

I founded FitGuana because I believe the best fitness practice teaches you many things and continuously should improve your mind and body. 

The fitness industry can be confusing yet much comes down to motivation and enjoying what you do in a safe environment.  I don't believe in shortcuts and my always progressing goal is to become and train well rounded athletes of all levels.


Throughout my athletic career:

  • My college degree taught me how to manage groups, be creative and innovating in coaching as well as research and process new information and data.

  • Competitive road cycling taught me how to pace myself and balance my energy reserves for long physical challenges.

  • Lifting weights has taught me to identify strengths and weaknesses as well as learning what my body is telling me.

  • Yoga has taught me to relax and channel energy.

  • HIIT training has taught me to push my boundaries.

  • Martial arts has taught me to keep pushing and not give in after a setback.

  • Grappling has taught me to control my breathing and body, even in times of despair.

  • Curiosity has led me to a never ending path of learning what I can about nutrition, supplements, recovery and so much more.


The key is to learn from everything you do.  Keep your eyes and ears open and learn whenever and from whoever you can. 


That is what FitGuana does.  Innovative, creative and efficient sessions which expose your mind and body to many different facets of fitness and wellness to become a healthy and well rounded athlete.  


ACE Group Fitness Instructor

ISSA Certified Fitness Trainer

ISSA Certified Nutrition Coach

Pre and Postnatal Certified through Girls Gone Strong

CRP / AED Certified

Kim H.

Group Fitness Instructor / Personal Trainer

Kim Hadermayer is a certified personal trainer who specializes in training pre and postnatal women.


She earned this additional certification through Girls Gone Strong - the industry's most comprehensive and respected evidence-based program for coaching and training pregnant and postpartum women.


A mother of two who lives in Ridgefield, CT, Kim struggled to find knowledgable trainers who could help her safely maintain her desired level of activity throughout her pregnancy and make sense of the varied and confusing information sporadically found in magazines and on the Internet.

After speaking with dozens of other women struggling with postpartum side effects in her work as a group fitness instructor, she decided to study the science behind pre and postnatal fitness and well-being so she could create safe, trusted and effective programs women need and give them the confidence to be the healthiest they can be for their growing families and, most importantly, for themselves. 

Kim is also Group Fitness certified through ACE and a Certified Fitness Trainer through ISSA.  She is also CPR / AED certified.

More about coach Kim:

- Favorite workout song: Anything upbeat that I can sing along to. Or dance to. I'm thinking Rihanna, Janet, Pink....

- Favorite exercise: Anything that involves squats. I don't know why, but I can squat for days.

- The exercise that makes me least excited: The pull up. Meh.

- If I could, I would spend all day working this muscle group: I can't pick...I love a total body workout!

- Best dance move: No comment

- Fitness related memory I’m most fond of: Working out during most of my pregnancy with the my second daughter. I wish I had video of me doing kettlebell swings 8 months pregnant! 

- Biggest fitness goals: While running a (much) faster 5K would be an ideal tangible goal, I really just want to be the healthiest, fittest, best me I can be.
