CASE STUDIES
The Situation
For over a year, Roxanne lived with sciatic nerve pain that would not let up. She tried everything the usual route offers, chiropractor, massage, and injections, and got only temporary relief each time.
The Result
After working with Jay, the pain was gone and she was walking tall again. What years of other treatments could not fix, a precise, individualized exercise process did.
“I had sciatic pain for over a year. Tried everything, chiropractor, massage, injections, with only temporary relief. After working with Jay, I was pain free and walking tall again.”
-Roxanne W.
The Situation
A 74 year old client was still living with discomfort nearly two years after hip replacement surgery, unsure whether something had gone wrong with the recovery.
The Result
After just three months working with Jay, the discomfort that had lingered for almost two years was largely gone. The approach was different from the rehab they had been through before, gentler, more precise, and built around their body.
“I tried traditional PT before this and it did nothing for me. I’m 74, and after working with Jay for just three months, the discomfort I had for nearly two years after hip replacement surgery is largely gone. I’m so glad my friends suggested I see him.”

The Situation
Robyn did not work out and had no idea what she was doing in a gym. Starting felt intimidating. No real structure or guidance, and the worry that getting started would mean getting hurt.
The Result
Jay and his team met her exactly where she was and made every short session count without beating up her body. In her words, it changed her life.
“I had no idea what I was doing in a gym. Jay and his team met me where I was and completely changed my life. They made every 30 minute workout count without beating up my body.”

TESTIMONIALS
Real stories from people in Naples who got their movement, strength, and lives back.
Client, Naples
I came to Jay at Symmetry through a friend ‘s recommendation when I mentioned that my back had been hurting. At the very first appointment I was impressed with how Jay listened to me and observed how I was moving. Soon I was feeling much better and had exercises I could do on my own. In addition to correcting my immediate problem, he also connected me with Genn, who is such a knowledgeable, encouraging and kind personal trainer. I have lost weight, gained strength and developed a consistent exercise habit. I would recommend Symmetry to anyone who is struggling with pain or who needs help creating and sticking with a realistic, safe exercise routine.
Client, Naples
I was recently diagnosed with a rare auto-immune disorder, transverse myelitis in which my thoracic spine was riddled with inflammation resulting in my lower body losing significant function. Over the last 3 months, working with a Muscle System Specialist was and is the only route I will go to help restore more efficient function. A week ago, I had the pleasure to work with Jay at Symmetry Exercise Clinic in Naples, FL (I live 2 hours away in Boca Raton, FL). I walked in his clinic with the expectation of leaving feeling stronger and to say he exceeded my expectations is an understatement. Through his thorough assessments and ability to process the results, Jay came up with a great plan to help safely progress my muscular systems ability to function a lot better. We were able to work through multiple training sessions to identify proper exercises designed specifically for me that I was able to take back to Boca and work through until the next time I see him. Thank you Jay for your professionalism, knowledge and expertise in helping me get back on the road to recovery!
Client, Naples
I can’t say enough good things about Symmetry Exercise Clinic! My son, a D1 college baseball pitcher, started going there for an assessment and to work on his overall performance, and the experience has been phenomenal. The staff is absolutely top-notch—super knowledgeable, professional, and genuinely invested in helping athletes reach their peak. They took the time to thoroughly assess his movement, form, and muscle function, pinpointing areas that needed attention, like soreness he’d been dealing with from intense training. The sessions are only 30 minutes twice a week, but wow, do they pack a punch! The team designs targeted workouts that focus on proper movement, stretching, and strengthening, all tailored to his specific needs as a high-level athlete. They even addressed his sore spots, and he felt relief right away, which was a game-changer for him. What I love most is how they go the extra mile—recording videos of exercises for him to do at home, ensuring he’s set up for success outside the clinic. The results have been incredible. His form has improved, he’s moving more efficiently, and he’s stronger and more confident on the field. The staff’s expertise and personalized approach make all the difference. Jay has been especially awesome, and makes sure his clients know he’s always just a phone call or text away if they need anything or have any questions. If you’re looking for a place that truly understands athletes and delivers real results, Symmetry Exercise Clinic is the way to go!
Client, Naples
I began biweekly personal training with Gen over four years ago. Today I am not only in my best shape ever, my entire body feels stronger and balanced. Jay and Gen identified the areas that needed strengthening, and now I get a total body workout with special attention to my back and shoulder.
Client, Naples
After a car accident, I had been to chiropractors, pain management docs, and a massage therapist. I got temporary relief but nothing lasted. After seeing Jay just one time I noticed lasting relief. Within two weeks I was 70% better.
Client, Naples
"For a year and a half I suffered from sciatic nerve pain. Within two weeks, my pain decreased dramatically. He has since moved me into a weightlifting regimen, and my sciatic nerve pain is headed toward non existence."
Client, Naples
I went to a local chiropractor after dealing with an extreme lower back spasm for over a week. The pain was so bad I had to rely on pain medication and Icy Hot patches just to function. After four chiropractic sessions with adjustments, massages, and even trigger point shots, I still had no relief. A friend recommended Symmetry Exercise Clinic, saying that Jason, the owner, works miracles. My friend had chronic back issues for years and said after just three visits with Jason, his pain was gone and he was finally able to work out again. I decided to give it a try—and I’m so glad I did. After seeing Jason just once, my back pain was gone the very next day. No more pain meds, no more patches. I was honestly shocked and beyond happy with the results. If you’re struggling with body pain, I can’t recommend Jason at Symmetry Exercise Clinic enough. He truly knows what he’s doing!
Client, Naples
Jay is the best at what he does. You have a sore shoulder or elbow or ankle? Go to Jay and he’ll fix you right up. The only problem is that he’s so good at what he does that you might only need to see him once for each issue!
OUR PHILOSOPHY
Every specialist here brings their own background and certifications, but they all work from the same belief. Exercise should be precise, individualized, and built on science, never fads or guesswork. Here is what every name on this page stands for.
We treat the system, not the symptom
We do not chase the spot that hurts. We assess how your whole muscle system moves, controls, and tolerates force, then improve the quality of control at the real source. That is why our results last when other approaches have not.
Truth, ethics, science, and transparency
These are the values that drive everything we do. No hype, no trends, no selling you something you do not need. Just honest, science based exercise and a clear explanation of why we do what we do.
One on one, always
Every session is private and fully focused on you. No crowded floor, no waiting for equipment, no generic plan. Your specialist is booked for your time and your needs alone.
Built around you, adjusted as you go
No set routines and no one size approach. We build your process around what your body can tolerate and is ready for, then adapt it in real time as you progress.
Results you can keep
Real change takes time and consistency. We are not interested in a quick burst that fades. We build progress you can maintain for years, and teach you how to keep it.
- TAKE THE FIRST STEP

Every plan starts with a consultation. You will sit down with a specialist who listens to your goals, assesses how you move and what your body is ready for, and builds your training process around you. No set routines, no guesswork, just a clear path to lasting strength and capability.
