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.

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
