- ABOUT US
We Use Exercise Differently.
Most people are told to rest, push through, or simply live with it. We believe there is a better way. If you are here for pain, we have a unique system designed to find the problems no one else can. If you are here for traditional exercise goals, we have a process designed to help everyone, from a person managing multiple challenges to the high end athlete. In both cases the common thread is the same: a one hundred percent unique perspective and methodology built around you. No protocols, no cookie cutter workouts.
Everybody Is Unique
- Assessment first, so we treat the real source, not just the symptom
- We use 100% individualized assessments and interventions instead of protocols and routines.
- Progress you can keep, with results that hold up over time
Reviews
Since 2013 · Over a decade helping Naples move and feel better.
Symmetry was co-founded in Naples in 2013 by Jay Weitzner and Jan Kerrigan, originally a client, who shared his vision for a private studio where professionalism and fun would meet. Jay began his career as a personal trainer in 1999 and went on to become only the second person ever certified in the Muscle System Specialist method, developed by his mentor Greg Mack. The founding idea was simple and still stands today: no fads, all fitness. Real, individualized exercise that does what generic plans and quick fixes cannot. Over the years Symmetry has weathered hurricanes, off seasons, and even COVID, and through it all it has not just survived, it has thrived

Jason Weitzner
“I started Symmetry because I saw too many people told to just rest, push through, or live with it. The body is capable of so much more when you train it the right way. That is the whole reason we are here.”

- HOW WE HELP
Pain, Mobility, Strength, Aging.
Two Clinical Approachs.
Muscle System Specialist
Pain & Stiffness
If pain, stiffness, or limited movement is holding you back, this is where we start. We do not chase the spot that hurts. We use a unique system to assess how your whole muscle system moves, controls, and tolerates force, then find exactly where your quality of control breaks down. From there, we build a precise plan to rebuild it, one hundred percent tailored to your body. It is designed to find the problems others miss, so you can move and feel better for good.
PERSONAL TRAINING
Mobility & Everyday Life
If you are ready to get stronger and stay capable, this is your path. This is not random workouts or a one size plan. We assess what your body is ready for, then build a precise, progressive process around your goals, your history, and what you can safely tolerate. It works for everyone, from someone managing multiple challenges to the high end athlete, and it adjusts in real time as you progress. The result is real strength you can sustain for decades, without unnecessary injury.
