ABOUT US
WHAT IS “JACKEDNLEEN”?
JACKEDNLEEN is a health, fitness, and transformation brand founded by husband-and-wife duo Jack & Eileen Oosten.
Their names, combined, naturally reflect the physical goal many people chase — to become jacked and lean.
However, the brand stands for far more than just aesthetics.
To be JACKEDNLEEN is a mindset.
A standard.
A way of living.
It means becoming strong in body, resilient in mind, and grounded in purpose. It means building a life that is harder to kill — physically, mentally, emotionally, and spiritually. #H2K
With over 20,000+ hours of personal training experience and a decade of helping hundreds of clients transform not just their physiques but their confidence, habits, identity & lifestyles, Jack and Eileen are on a mission to raise the standard of what health and fitness coaching should be.
Because real transformation isn't about quick fixes or just looking the part — it's about becoming the kind of person who shows up powerfully in every area of life.
OUR MISSION:
To create well-rounded, robust, badass humans.
OUR VISION:
A world where all humans are JACKEDNLEEN, and Harder to Kill #H2K
