What People Are Saying About Ten Fld NYC
With over 5 stars on google, here are some reviews of what clients have said.
As a newcomer to physical training, I've found Jonathan to be an exceptional guide, making my journey both enjoyable and exciting.
Patricia De Los Santos
CFO
I have been training with Jonathan for several years now and I would recommend him highly to anyone interested in fitness and weight training.
Seth Weisburst
Lawyer
My husband and I have been training with Jonathan 3-4 times a week since we moved to NYC in May 2017. We consider the time, effort and cost to be the best investment we could have made (and continue to make).
Marsha Weisburst
Retired Lawyer
Been working with Ten Fld for about 3 years now and it's the best. When I first started, I couldn’t even do a push up, but now I can do different variations.
Soeun Kim
Anesthesiologist
What stands out the most is that the impact of our work together lasted well beyond the sessions and If I’ll have the opportunity to train with him again, I definitely would!
Meryem Jud

Jonathan is a great trainer Working mitts with him is a great workout plus I’m learning how to be a better fighter! Also his Physical training knowledge is really helpful for me.

Best trainer ever, would train with him if I back to New York.
