KAI Fitness

Small group personalized training, one-on-one training, boot camps, sport specific training, rehab.

I have worked out for over 35 years with resistance training, swimming, pilates, yoga, and martial arts. At 41 my body was crippled with pain, muscle imbalances, and improper movement patterns. For the past 10 years, I embarked on a journey of learning everything I could involving how to correct these issues. Along this journey I was blessed with the birth of my son Dylan Kai, and this gave me the initiative I needed to finally complete the preparation stage of, "The Perfect Exercise and Wellness Facility".

🌊 41 Waves. Zero Quit.

Mark Adamec is 61 years young and proof that age is just a number when you train with purpose. He’s in the gym 5–6 days a week at KAI Fitness, building not just muscle, but a world-class cardiovascular engine.

Yesterday in Atlantic Beach, the waves were firing — and so was Mark. He didn’t just ride — he owned it — taking 41 waves back-to-back without stopping.

This is what KAI Fitness is all about: helping you stay strong, agile, and ready to live the life you love… at any age.

Drop a 💪 in the comments to cheer Mark on!

🔅Client Spotlight: Meet Meredith Bolton
Originally from Atlanta, Meredith 52 years young made the move to the beach last year—and after biking and walking past KAI Fitness for months, she finally decided to stop by. And we’re sure glad she did!🙏🏻

Since January, she’s been a regular in our group fitness classes 3 x’s a week, mixing cardio, toning, and strength training to support her active lifestyle.

With 2 sons—one a recent UGA grad and the other currently a student (Go Dawgs!)—Meredith knows the value of staying strong and healthy for life’s next chapters. A runner and cyclist at heart, she came to KAI looking to build strength and protect herself from injury—and found way more than just a workout.

“I love Scott’s philosophy and attention to form and function. He makes sure that I am doing the exercises that support the types of activities I enjoy while being mindful of protecting areas that I am susceptible to injury. It also helps that the environment is so friendly. I was intimidated to go to a new gym after so many years of working out alone, and this has been the best choice I could have made.” We’re so glad you’re part of the KAI Krew, Meredith🙌

Our Story

I have worked out for over 26 years with resistance training, swimming, pilates, yoga, and martial arts. At 41 my body was crippled with pain, muscle imbalances, and improper movement patterns. For the past 5 years I embarked on a journey of learning everything I could involving how to correct these issues. Along this journey I met my beautiful wife Donna, who also had an extensive background in health and fitness. She gave birth to our precious Dylan Kai, and this gave me the initiative I needed to finally complete the preparation stage of, "The Perfect Exercise and Wellness Facility". Thank You Dylan and Donna for helping me reach this long awaited goal. - Scott Hernandez
