Jonathan Kuiter - Bio

My name is Jonathan Kuiter, I was born in the Netherlands, after a few moths of being on this lovely Earth I moved to Africa where I spent the first few years of my life, ultimately returning to the Netherlands at the age of 4. 
It was in the Netherlands where I fell in love with baseball.  After years of playing baseball in the Netherlands, and honing my skills, I made it as far as the Dutch Minor Leagues.  This road was paved with countless hours of practice, conditioning and strength training. 
I pursued my MBA at a University in the Netherlands, and after a few years in the business world (in the Netherlands and the U.S.) After helping a friend of mine lose 40 pounds by providing nutritional advice and working out with him on a daily basis I realized that my true passion was health and fitness. This realization led me to become a Personal Trainer at Equinox.
My clients results truly are the most gratifying moments of my day. Varying from clients losing weight, gaining muscle or  performing their first ever pull up. My passion for health and fitness has led me to become the number one performing Equinox trainer in Northern California as well as in the top 25 performing trainers of Equinox world wide. 
My success as a trainer is partially due to helping my clients with their diets and I have finally found a protein bar that I would highly recommend to any of my clients as a great snack, enter the MAMMOTH BAR.
