"Jesse is the practitioner I wish I had found a decade earlier. He would have prevented an enormous amount of frustration and helped me avoid wasting time."
Martin Chavez · Former CFO, Goldman Sachs
The Practitioner
Jesse Gaynor.
For seventeen years, Jesse has worked privately, one body at a time, with the people their organizations cannot afford to lose. The practice is small by design. The standard is non-negotiable.

Biography
Jesse began his practice in 2008 with a degree in exercise science, a credential in nutrition, and the unfashionable conviction that posture — not protocol, not program, not gear — was the single undervalued lever inside the entire field of human performance.
Over the next seventeen years, that conviction was validated one body at a time. He logged twenty-five thousand hours of one-to-one work, almost exclusively with high-output professionals: founders, partners, operators, and eventually the senior leadership of one of the most demanding institutions in modern finance.
What began as a fitness practice became something else entirely — an architecture. A way of designing the physical infrastructure an executive operates on, with the same rigor they bring to every other system in their life.
Today the practice is private, remote, and intentionally small. Jesse works with a limited roster of operators each year, delivered globally via Zoom. The work is the same whether the client is in Manhattan, Singapore, or a hotel suite in Geneva: precise, unhurried, and built to compound for the next thirty years.

In Their Own Words
"Highly recommended. Jesse was very attentive to my personal needs and when I wanted to use more weights he suggested to focus on the posture instead. He helped me focus on my long term goals."
Y D. · Venice, CA
"He has an intuitive understanding of body mechanics, and he's more than just a trainer, rather an educator. I've noticed a dramatic improvement in my posture, confidence, balance, strength and mobility."
Mark K. · Los Angeles, CA
"Jesse is no ordinary fitness trainer. He takes a personal, thoughtful and wholistic approach with each of his clients. I would highly recommend this highly-skilled and personable professional."
Bert S. · Scottsdale, AZ
"His eye is trained to note even subtle mis-alignments. At the end of each session, I always felt invigorated with a sense of lightness, body symmetry, and well-being."
Francine F. · Palo Alto, CA
"Jesse's process goes far beyond what I would describe as 'personal training.' His understanding of the human body is truly holistic. He was the catalyst for a lot of very helpful life changes."
