I'm Eunsoo, founder of Strong Inside & Out.
As a TRX, TRX Pilates and National Academy of Sports Medicine (NASM) Certified Personal Trainer, I help people build mobility, stability, strength, power and confidence through personalized training that focuses on how the body moves. My goal is to create a supportive, structured environment where you can train safely, move better, and achieve real, lasting results.
With a Stanford Ph.D. in Electrical Engineering, I bring a thoughtful, analytical, and systematic approach to every session. That means clear guidance, attention to proper form, and steady progress you can trust.
I believe the body is sacred, not simply something to change, but something to care for. “Your body is a temple of the Holy Spirit” (1 Corinthians 6:19 - 20) shapes the way I view fitness, as an opportunity to honor the body with gratitude, discipline, and respect.
No matter where you’re starting, I’ll meet you there and help you grow Strong Inside & Out.

"It's been almost 10 months since I started TRX with Eunsoo, and I feel stronger than ever. She thoughtfully organizes every class and gives clear explanations on how to perform the movements. I truly enjoy her TRX class. Highly recommended!" - Sona on March, 2026
