About

I work closely with my clients and their families to elevate not just training, but their entire lifestyle. I take deeply rooted pride in being trusted inside their homes, their routines, their long-term health goals, and I’m honored when that trust grows into something that feels like family. My background with a high-level concierge health and human performance startup in Philadelphia shaped everything about how I operate today—confidentiality, punctuality, time-efficiency, and results without excuses. We build anywhere. We optimize everything. Today, I deliver orthopedic rehabilitation, performance training, and lifestyle optimization directly to you - privately, discreetly, and with uncompromising standards. This is the work I do best.

In my 1 meeting with Jonyul 6 months ago, he taught me skills that have made a difference in my workout. A slight adjustment in stance alleviated chronic knee pain. He taught postures that help me not just exercise, but do it more effectively. He's intentional and listened to my needs.

I decided to train with Jonyull after my daughter emphasized his attention to detail. It was my first time back in the gym in quite a while, and I had several prior injuries and muscle imbalances. Jonyull is amazing and enabled me to push myself hard in a safe manner. His attention to detail actually put my prior physical therapists to shame. He would notice small things, like if I picked up my heel or my knee drifted, and correct them immediately. His nutrition and recovery advice also helped me train harder with significantly reduced soreness. I wouldn't have neglected strength training for so long if I'd had someone like Jonyull earlier. His value proposition: If you want to cheat on your workouts and have someone pander to you, he's definitely not your guy. But if you are ready to go on a fitness journey with a very knowledgeable, motivating, and engaging trainer, you should definitely consider Jonyull and discuss your situation and goals with him.

FAQs

What should the customer know about your pricing (e.g., discounts, fees)?
Session pricing varies between 100-150/ hr depending on the program bought into! Let's chat about private, 1v1 and small group packages!
What is your typical process for working with a new customer?
Initial evaluation, intake and movement screening + workout then goal setting, nutrition analysis and lifestyle habits review!
What education and/or training do you have that relates to your work?
My primary background as a board certified athletic trainer (ATC) allows me to dive deep into your orthopedic/ sports rehab needs; my background in strength and conditioning allows me to dive into your body composition and fitness needs; both allow me to bridge the gap between the clinical + injury preventative work and your strength + longevity progressions!
