It’s about communication

And building relationships

He has the unique ability to establish long-term partnerships with his clients and community members, which has resulted in an extraordinarily high amount of long-standing relationships. Many Kai-fitters have trained with Kai for a decade, or two…


Don’t forget about the big picture

John Jasper

Senior Trainer 

John has cultivated his passion for fitness and general wellness since he obtained his BS in exercise technology from A&M (Class of ‘96). John is certified through American Council on Exercise and had completed kettlebell certification through Cross Fit. He has been a trainer for KaiFit since 2012.

It’s a journey

John’s philosophy: Exercise is a journey to learn about yourself. By challenging yourself to improve your fitness, you can find your potential, and limitations, which are the cornerstone of personal growth. The pursuit of improving strength and conditioning leads to a cascade of positive results that go beyond basic health, and get us to a better version of ourselves.

Perspective is everything

John took a brief hiatus from his career to be a stay-at-home dad, which provided him with new perspectives on everything! Trying to keep up with his three boys is yet another motivation for John’s dedication to wellness
