Ninja Success Stories:

David lost 27lbs and 5.5 inches around his waist in 10 weeks on the Primal Shred Program… without doing a single high intensity workout!

“I have had other trainers at LA Fitness, Equinox, and in private studios; Jonathan is radically different on many levels. I feel like I’m in shape for the first time in my life. The kinds of movements we do are totally different than anything else I’ve done before.

I really enjoy knowing Jonathan personally, he is a friend, but the biggest difference is the results; a major yet sustainable lifestyle change, understanding the process AND losing 25 lbs and almost 5.5 inches around my waist in 10 weeks… without a single high intensity workout!”

David Rosen ~ Real Estate Entrepreneur 


Nancy lost 3.5 inches from her waistline in 20 days!


“The most surprising thing about working with Jonathan is how fundamental the movement is and at the same time — how entirely transformational it is! His method of practice feels so, so great; is so nourishing to the body; and is very different from the standard operating procedures of most typical trainers, which is so refreshing and a big AHA!

I’ve lost 8 pounds and shed 3.5 inches from my midsection in just 20 days and I feel amazing!

If you’ve tried the typical fitness regiments and you want something different that has serious human and health benefits to transform yourself from the inside out AND change the way you think about your body and your relationship with food forever — hire Jonathan. Best decision I’ve ever made. ”

Joe lost 20 lbs in under 12 weeks on the Primal Shred program, and has kept the weight off for 18 months and counting.

After 14 years of working together, Jonathan has become much more than a trainer. Words that come to mind: coach, guide, friend, advisor, teacher, seer, healer. I think that’s what separates him from others; there’s a much broader holistic view of wellness that includes the mental and the emotional. Since starting his Primal Shred program, I’ve lost and kept off about 20lbs and recorded personal records at 5 different race distances (5K, 4M, 5M, 10K, and 15K). I run less per week, but run faster, with less pain and more joy.

Beyond the overall health and physical wellness benefits, I’ve seen measurable changes in my moods; they’ve evened out significantly. I also have a better understanding of my body and its relationship to exercise and food. I’m more equipped to deal with the day to day stress of my job, and my artistic work has evolved in ways that are directly linked to the shifts that I’ve experienced physically. I’ve embraced the idea that less struggle can yield deeper, more positive results, and have experienced professional work success which is directly related to this ethos.

“Working with Jonathan changed my life.  I use the movement and breathing techniques I learned from Ninja Training almost everyday because it’s been so effective for me (more than any talk therapy, medication or alternative treatment for depression I’ve received). Jonathan is an amazing resource and a well of wellness and healing.”

“I love my trainer Jonathan! He makes working out  both fun and super effective.  I always look forward to coming to NYC and training with him, I just wish he was in LA so I could train with him all the time.”


Jillian Michaels ~ Fitness Icon ~ NBC’s “The Biggest Loser”






“As a chef I eat a lot and work crazy hours and sometimes get stuck in a terrible cycle where the gym seems like somewhere thousands of miles away. Jonathan not only got me back into the gym but made me look at it in an entirely new way.  His knowledge of the human body and what exercises to do was really eye opening and life changing. I find myself making time that I never thought I had to get into the gym 4 to 5 times a week instead of 4 to 5 times a year, and doing exercises I never even heard of before thanks to Jonathan. I used to have lower back pain pretty regularly, but now it’s all gone directly because of these new exercises.”

“Jonathan is just at a whole different level, both as a friend and a trainer. He’s super experienced and crazy knowledgeable, sure. But the true, extraordinary benefit of training with Jonathan is that he’s your partner, your trusted friend along the path to deepening your relationship to your body. Because he knows that long-lasting, profound results are what really matter; that awakening and finding the ninja inside of you can change your life forever. And he truly cares you get there just like he has.”

“Jonathan has such a beautiful and beneficent lens through which he sees everything.  His work has resulted in a new closeness to myself and my body. He is a diamond in the world of fitness- providing space for healing, deep contemplation, and kickass physical results all at once.”

 Elena Brower ~ Author ~ “Art of Attention”



Don Saladino“Learning Yoga, Tai Chi, and Qigong aka “ninja training” from Jonathan has been a profound experience and deeply therapeutic. He is always 100% present and focused; he clearly loves what he’s doing and it shows. Every single time I leave a session with Jonathan I feel incredible. My body feels better, more balanced and more mobile; it also recovers faster and I sleep deeper! And quite frankly, I’m even happier than before.  I couldn’t speak more highly of him, as a trainer and now as a friend.”

Don Saladino ~ Strength Coach & Owner ~ Drive 495


“The most surprising thing about working with Jonathan was learning the ways I could work out that were fun instead of a chore, even stuff I could do at home. I gained strength, confidence, and overall wellness just by learning to do a little bit of movement every day. Incredibly, the physical and emotional resilience I gained through his training directly helped me overcome some issues with addiction, and for that I am deeply grateful.”

Rohan Wijegoonaratna ~ Technical Recruiter



“The primal movements Jonathan taught me are unlike any other exercise I’ve done before and helped me heal a lower back injury with sciatic nerve pain.

As a veteran runner of 30 years and gym junkie, I was surprised to feel worked out after a primal session because the movements are quite gentle.  

I’m now running again and training for a marathon. I now know how to get a great workout without excess intensity.  The practice feels so good, like untying knots in my muscles!  And it gives me better body awareness, helps me avoid injuries, and keeps  me running pain free. “

Martin McElhiney PhD ~ Department of Psychiatry ~ Columbia University





“This is going to sound ridiculously corny, but working with Jonathan has literally changed my life.  I could immediately tell he really cared about me and my goals, and I truly believe that Jonathan cares about my mind, body, and soul.  He is SO MUCH MORE THAN A PERSONAL TRAINER, he is more like a personal guru, a friend, and family.  I am so grateful for the results I have achieved while working with him.  I recommend him to all my clients and friends.  I am 35 and my body looks and feels better than it did in my 20′s.”

Adina Azarian ~ Owner of Adina Equities ~ NYC Real Estate Maven




“Jonathan’s expertise in personal training and passion for learning about the human body is only surpassed by his commitment to his client’s and their goals.  Through the years, he and his team have been there to guide, coach, and inspire.  I recommend his services to my patients every week, knowing that they will be in safe hands and will come back to me in a year much healthier.”

Dr. Warren Licht ~ Doctor of Internal Medicine






“Training with Jonathan has been one of the best decisions I have ever made. Aside from his vast knowledge of anatomy and movement, his positive outlook and encouragement gives me confidence during our sessions and forces me to be more proactive about training on my own. As a physical therapist, I would highly recommend Jonathan to my patients and know that they are in great hands!”


Karen Litzy, owner Karen Litzy Physical Therapy, P.C.






“I felt like a new person after 1 session with Jonathan.  I was taken by his incredibly sharp and intuitive assessments.  As much as we were communicating as we went along, I felt he always had an inner eye on what was needed.  A very special approach.  The Zen Trainer and the Art of Peak Mountain Climbing.”

 Natalie Galazka, Executive Producer





“Jonathan is an awesome, positive force of nature. He pulls everyone into his vision of a beautiful Life.  Every word he says is true.”
