About Me

Hi, I'm Xiaoyin

I come from an AI background — but it was my own body that changed everything. Years of chronic pain pushed me to study movement science, understand biomechanics, and figure out why I was hurting.

I trained myself back to full strength. No more pain. Along the way, I helped friends do the same — and realized this was what I wanted to do for more people.

Today I hold an ACE Personal Trainer certification and a NASM Corrective Exercise Specialization. I bring both the analytical mindset of someone who studied AI and the lived experience of someone who has been through it — to help you build a stronger, pain-free body.

My Approach

The Shine Method

Five principles that guide every session, every program, every client.

S
Science First
Every exercise choice is backed by biomechanics, exercise physiology, and neuromuscular science. No trends, no gimmicks — just what actually works.
H
Heal to Perform
Pain and old injuries shouldn't hold you back forever. We address the root cause, rebuild strength around it, and get you moving freely again.
I
Intelligent Training
AI-assisted programming that adapts to your body's data — so your plan evolves as you do, not the other way around.
N
Nutrition-Informed
Training and nutrition work together, not in isolation. Every program considers how you fuel your body to support recovery, performance, and long-term results.
E
Empower to Be Independent
My goal isn't to keep you dependent on a trainer forever — it's to give you the knowledge and tools to train confidently on your own.
Client Results

Real people,
real changes

"I'd been dealing with lower back pain for years. After 8 weeks with Xiaoyin, I finally understand why it was happening — and it's gone. The way she explains the body is unlike any trainer I've worked with."
"I never thought I could actually build muscle — I always thought I just wasn't built for it. Xiaoyin's AI-powered plan was completely tailored to me and I've seen more progress in 3 months than in 2 years on my own."
"What sets Xiaoyin apart is that she teaches you, not just trains you. I now know how to warm up properly, what to eat around workouts, and how to listen to my body. I feel truly independent in the gym for the first time."
