Where do I begin?
I met Kai via and was immediately hooked after the first session. She has tailored each and every workout session to my personal fitness goals to maximize the effectiveness of seeing the results I so desired. I absolutely hated working out before and was very inconsistent. She’s not only taught me discipline, but she makes working out fun! 
This whole process has been therapeutic to me on an emotional level. From boosting my self-confidence to feeling comfortable in my own skin. It’s a game changer to say the least! I don’t just consider Kai a fitness master/guru, I consider her my friend. She’s helped me become a better looking and much healthier version of myself. 
I am thankful and grateful for her guidance in helping me achieve my goals.  I would highly recommend her to anyone that is simply wishing to become a better version of themselves.

Kai Kelly is a remarkable trainer!  Kai has been trainning our corporate team for a few months now.  Within 60 days, I noticed changes in my body tone and in the ability to improve my performance throughout her exercises.  Kai pays close attention to detail and makes sure that I am completing the exercises with proper form.  I would highly recommend Kai Kelly for personal or corporate training

Kai gave me the structure and accountability I needed in my workout routine.  She knows when to push me and creates a safe, supportive environment to do so.  In just a month, I have enjoyed improved strength and body awareness, and I am beginning to see changes in all of my "problem areas."
