Johnny Mathis

“Johnny - I know you love to sing (I do too). This is a small gift to you (whom I admire and respect). My trips to the gym in the morning have been made special by your kindness and friendship. Bless you John.”

Your Pal,

John M.

Rick Yune

“I’ve been with John since the Fast and Furious. He’s helped me get in shape - stay healthy - more than anything - he helped me understand how my body works.

He has not only been my trainer but we are dear friends.”

Hunter Ives

“John is the best trainer in the world in my mind. I’ve trained with many people but not anyone that I still call a good friend. The biggest thing that makes him different is how much he truly cares about you and what your goals are. And he focuses on every area of your being to help you get there. Working in Hollywood sometimes requires molding your body to fit a certain form. I can say with you I've never second guessed that I can achieve that.

Your the best brotha,”

Hunter Ives

Ziggy Marley

“Training with John has literally saved and changed my life, its a perfect fit, no pun intended. it never gets boring as we mix it up a lot from weights to martial arts to pure fitness stuff he keeps it real. When you train with john you are getting real life fitness and strength not gym fitness and strength sure you gonna look good but you gonna be functional too. You’ll be ready for whatever the world can throw at you and thats why we’ve been working out together for over a decade he’s more than a trainer he’s family.”

Jen Pollack Bianco

“John Petrelli is a fantastic trainer and person. He knows how to challenge his clients and keep them motivated and working towards their fitness goals. He cares about his clients and never hesitates to go the extra mile (or five) to address specific needs and concerns. As an added bonus, he is a funny and interesting guy. On days when the last thing I want to do is workout, spending an hour with John is motivation enough to get me to gym.”

Jen Pollack Bianco

Michael Barker

“My story is a long one as I am soon to be 75 but, thanks to John Petrelli, feel like I’m 45. I have worked with John for almost 13 years and to my benefit, he has kept me focused on improving my body (and thus my mind) in many ways. His caring, but disciplined approach to training, is committed to excellence.”

Outside the gym

Technology used properly definitely serves a purpose BUT my wife and I have come to realize the importance of connecting with nature and our friends and family. We believe it's imperative to pass this philosophy on to our youth. Creating a connection that ties nutritional awareness and knowledge, with physical movement and community.
