"Dr. Jack,
Your work to promote Fitness and Strength Training has made such a powerful impact on individuals of all ages.  Your leadership at the seminars at the Arnold Schwarzenegger Fitness Festival is outstanding, and your talks are always one of the highlights of the (Arnold Schwarzenegger Fitness Festival) weekend for me."
I am proud to know you. 
Governor Arnold Schwarzenegger


Dear Dr Jack,

You have been such a positive influence in my life. Consulting with you was the best choice I ever made. I would have left 40 years of Culinary Arts on the floor of the gym and had a life of counting to ten. Your support has been a guiding light for me. Your fire, enthusiasm, knowledge, and guidance now has me helping people with consulting, cooking demos, meal design, doing more than I could have ever dreamed. It is awe inspiring to think of the people you have touched. Thank you just doesn’t say enough you have changed my life and even more the lives of the people I or we serve.

"Dear Dr. Barnathan:

First, thank you for completely changing my life!

Your seminars leading up to my being awarded Master Trainer Status have completely impacted everything I do - both personally and professionally!  Beyond all the knowledge I've gained is the inspiration you touch all your students with.  You help us understand how our work is so much more than we ever understood before.  I'll always be grateful."

Never meeting Dr. Jack until I attended his NY Strength System seminar in Los Angeles I found myself completely engaged in his educational yet entertaining lecture.

Dr. Jacks enthusiastic energy is contagious. I promise you will leave his seminar totally inspired and ready to take on the world."

Jessica Cousine

"Motivating and innovative are the two words which come to my mind after attending Dr. Jack's seminar. If you are looking for that extra "push" in your training skills, or even just to further your education, this is- bottom line- the place to be."

We met Dr. Jack in 2002 and he made an indelible impression on us both.  
We followed him over the years and have gained much from attending many of his seminars. With Dr. Jack's keen sense of intuition, he locks right in on your talents, uniqueness and strengths.  
He then helps you SEE them. We decided to ask Dr. Jack to coach and mentor us and the important projects we have begun.  With his expert direction, support and our bond with him, we are an unstoppable force!
We have a clear trajectory, and we are enjoying the journey that we have embarked with him.  Dr. Jack is a dear friend, mentor and a caring, loving human being!  We can't say enough about him - we HIGHLY RECOMMEND him to anyone who is sincere about realizing their dreams.

Sincerely, with love,

When I met Dr. Jack at my first ISSA seminar, I thought, “This man is Great!” I was drawn to his science driven teaching style and his obvious passion for helping others achieve their goals. Since 2002, I have attended as many of his workshops and seminars as possible.  Throughout all of my schooling and different teachers, not one has made such an impact as Dr. Jack. Few people have the wealth of knowledge in science, business and real life experience he holds. Although he only appears to be one man, his combination of knowledge, skills and talents have made him into an unparalleled, successful team of people in the Health and Fitness Industry.
I opened my own gym, Pinnacle Fitness, in 2008. Still, I asked myself what I could do to take it to the next level.  I knew without hesitation what I needed: I called his Executive Director Nicole Bruno and asked her, “How can I get Dr. Jack to Pinnacle?” In the beginning of 2010, I began consulting with Dr. Jack and the results have been incredible, terrific and real. More importantly, our collaborations are still continuing.

Dr. Jack has helped me tremendously, both personally and professionally. He is a great man with a love for teaching and helping others that is unrivaled. Thank you very much Dr. Jack for being YOU!

Dr Jack:

An inspiring, motivating, positive, fun, and helpful person to name just a few things about him.  He has helped motivate me, keep me on top of my own business and field, keeps me reaching for new heights and goals, brings me happiness every time we talk on the phone, and is such a positive influence to be around. 
His energy just grabs a hold of you and makes you want to learn more not only about the health profession, but also yourself.  He brings out the best in you with his coaching and consulting experience, and by giving yourself this extra gift and push of his skills, you can not fail. 
He is truly an amazing person, good soul, and happy human being.  I am so thankful that I got to meet him through the ISSA, and since have furthered my career with him, and also my own self.  He will help you succeed by making you look deep into yourself and find what really motivates you in life, and bring those goals out of you to help you become successful! 
Thank you for being such a good friend and mentor Dr Jack!  You are the best ;)

From the first day I meet Dr. Jack my life changed!  His knowledge and passion just seeps through him with excitement.  He always had me at the end of my seat bobbing my head all day to everything he had to say. 
After attending a couple of seminars my husband and I decided to open our own private fitness center.  Dr. Jack has helped us in more ways than he could ever imagine before and after we opened.  With his guidance of training, fitness, nutrition, our business consultations with him, acceptance and appreciation of this industry we were able to open our doors loud and proud for our community.  Plus with his guidance we were booked after only being opened for a few months!
But even after opening our doors he has always been there for us with his love and support.  Our consults are the most amazing experience with Dr. Jack. .  Thank you Dr. Jack for being an inspiring model for all of us world wide!  B-Xtreme Fitness Pro Center, Ltd family proudly and gladly thanks you and you are always welcome in our home! :) -Niki Bryant

I had the pleasure of meeting Dr. Jack Barnathan and my life has not been the same.  I decided to take Dr. Jack’s Masters of Fitness Design course which allowed me to also mentor him the past year. 
My business, “No Mullarkey” Personal Training, has hit it’s all time high since hiring him as my business coach. 

Dr. Jack has been my angel as he has supported me and encouraged me to shoot for the stars.  He 100% has my back!

He also has been a huge support with my other goals of modeling and getting published.  Since meeting Dr. Jack I have been published in almost every major national publication in the fitness industry!  Due to this national exposure my online business has tripled. 

I can’t thank my angel enough for supporting me and urging me to think outside of the box.  If you are feeling stuck and want to take you business to the next level, it is a no brainer to seek out Dr. Jack Barnathan for consulting support. 

Thank you Dr. Jack for all that you do.  You work so hard at helping others achieve their goals in life and business no matter how big they are.  You never cease to amaze me and I am so excited to see what the next year has in store for us.  Thank you for genuinely caring about your clients and for being so positive and passionate at life.  The sky is the limit............YEEHAW BABY!!!!!!!

Consulting with Dr. Jack is more than a daily dose of adrenaline for me; it is a one of a kind experience. The energy he cultivates, conveys and exuberates in every conversation forms an invincible aura against the mental and emotional punches that come my way, bar none.  I am moved by his keen desire to showcase my unique qualities and strengths, guiding me to the pinnacle of my success in the fitness industry!
Thank you Dr. Jack for your friendship and expertise.

Dr. Jack has the rare passion and ability to inspire all he comes across. In a time when individuals are merely existing he is truly living and breathing all that he preaches. To say that Dr. Jack changed my life is an understatement. He taught me how to live. To focus on the positive aspects of life and to let go of the negatives, which hold us all back. Not to live life with blinders on, afraid to make eye contact or say hi to others because were in a rush, but to stop and smell the roses every now and then. To interact and learn from all we come across.  Through these life lessons I’ve found my true calling and words can’t even express how incredible a feeling that is. I owe him everything and am honored to have met him and call myself a Fitness Pro.

"Without a doubt, the reason for where I am in my life is largely shaped by Dr Jack Barnathan. From the moment I met Dr Barnathan almost 15 years ago; his steady guidance, teachings, support and inspiration has impacted the course of my life profoundly. I have benefited immensely in both my athletic and business professional careers.

As a long distance runner, Dr Barnathan’s coaching has helped me perform stronger and consistently with every race I completed – I earned personal records each time, including a third finish ranking in my age group at the 2014 Montreal Marathon

On a business level, Dr Jack has mentored me on how to competitively distinguish myself from others. In so doing, I learned how to climb the corporate ladder, as a leader. My sense of style in interpersonal business relationships is the result of attending and learning tremendously from Dr Barnathan’s teachings. 

It is incredibly rare for a person to possess both unparallel business acumen and be renowned also as a leading authority in the arena on health/fitness. I’m honoured to know Dr Barnathan; he is the unique individual that seamlessly fits this profile."
