Hi, my name is Jesse Gaynor and I’m a Personal Trainer.

I have 14 years experience as a fitness trainer and degrees in nutrition, exercise science and post university studies in physical therapy and postural alignment (degrees from University of Southern California USC).


I work with a variety of populations. Everyone from Business professionals and their wife’s or husband’s looking to find expertise with health and fitness. To elderly clients that want better strength, posture and help with eliminating aches and pains.


AFTER 1 SESSION- you will have noticeable results in the way your body looks AND (if you have aches/pains) you will feel noticeably less pain or none at all!

I’m willing to say this because of my experience and track history over the years.


I offer a free consultation session done remotely for anyone that is interested in being a client!

If you want someone with trusted experience, education, and results try me out.

"Since I have been working with Jesse pain from injuries I had in my

shoulders and knees has been drastically reduced.  I've also lost 20 lbs. and 10% body fat!" -Gilad K.

5 Star Review


If you're looking for a trainer who understands your goals and adjust based on your lifestyle then Jesse is the guy for you. I had recently developed a hip condition due to over training and poor movement patterns (thanks Crossfit) and needed someone who understood body dynamics and did more than just show me a routine and yell at me while I worked out. In addition I wanted to lose body fat and improve my strength.

Jesse took a holistic approach and adjusted both my diet and created a work out plan that worked for me.  Jesse was able to boil things down to simple and practical concepts. Many of the things he recommended are cutting edge and the results speak for themselves.

I've worked with Jesse for a bit over four months and lost 25 lbs and went from 20% to 12% body fat. In addition my hip pain has improved dramatically. The workouts were very different from anything I've done before, but we focused on form and alignment to reduce reliance on over worked muscles and strengthen underused ones.
I highly recommend Jesse and trust his advice.

5 Star Review


Jesse is absolutely amazing. His technique leads to complete integrated strength throughout the entire body.


He is highly skilled in assessing his clients and implementing a myriad of different work-outs that train specific muscle groups to completely change posture for the better. He works with strengthening unused muscle groups, increasing endurance and balance, while assisting you in increasing bodily awareness and embodiment.


Working out with Jesse is tough, and also like a fine-tuned meditation inside the body. He also recommends diets that are absolutely amazing -- increasing your energy and vitality while trimming down your waist. His knowledge of herbal medicine and supplements are exceptional. I am a Naturopathic Doctor in the Santa Monica area.


Jesse is my personal trainer and I recommend him to all of my clients who are looking to optimize their health -- because I know that he can get anyone in shape, in the most efficient and holistic way.
