About STRH
What STRH is, how it evolved from AIS, and why it matters in a tech-driven world.
Sustainable Training for Restorative Health — founded by Jayze Lee.
What is STRH — and how is it related to AIS?
STRH (Sustainable Training for Restorative Health) grew from Jayze Lee's work with Active Isolated Stretching (AIS). It brings assisted mobility work into a broader approach focused on access, stability, and readiness for everyday movement.
AIS is the foundation.
STRH is the structure built around it.
Jayze's work with AIS began in Hong Kong in 2008. His experience with clients whose daily lives involved long hours of sitting helped shape the broader STRH approach.
STRH builds on AIS by connecting mobility work with stability and readiness. It reflects Jayze's experience working with people whose daily routines includes prolonged sitting and screen time.
Why STRH builds on AIS
AIS remains central to Jayze's work. His experience with clients also led him to look beyond a single session: how people use their available range, support movement, and prepare for the demands of daily life. STRH brings those considerations together through access, stability, and readiness.
The STRH Framework
1. Access
Use AIS and range of motion assessment to explore and improve available movement.
2. Stability
Develop the control and support needed to use that range in movement.
3. Readiness
Assess how the person moves and responds before progressing to more demanding activity.
From Hong Kong practice to STRH
Jayze Lee began working at Stretch Asia in Hong Kong in 2008. In 2011, he became a program director in development and training.
Working with clients whose routines involved long hours of sitting helped shape his interest in how assisted mobility carries into everyday movement. Over time, those observations informed STRH's focus on access, stability, and readiness.
Why STRH Matters
For practitioners, STRH offers a framework for looking beyond a single technique. It connects range of motion assessment, assisted mobility, stability, and readiness when considering how to progress.
For individuals, it means paying attention to the movement they have today, how they use it, and what they want to be ready to do next.
Why We Train Practitioners – NOT Routines
We don’t teach generic routines.
We train elite practitioners.
STRH takes AIS beyond technique—combining precision, system-level thinking, and real-world application. You’ll learn how to assist clients safely, intelligently, and effectively through one-on-one sessions that go far beyond memorized sequences.
You don’t need a background in fitness, massage, or therapy.
What you need is:
Focus
Curiosity
A commitment to precision
We train you from the ground up—so you develop skill, not just credentials.
What You'll Learn
✓ How to apply the STRH Method with precision, safety, and confidence
✓ How to read the body in motion, not just positions
✓ How to deliver mobility that holds up outside the session
✓How to build a high-value, sustainable bodywork practice
This isn’t a trend. It’s a career path.
STRH is built for practitioners who want mastery, longevity, and relevance.
STRETCH
"What if everything you thought about stretching was wrong?"
In Stretch the Truth, Jayze Lee examines common assumptions about flexibility and explores why the way we stretch matters. Drawing on his experience with AIS, he invites readers to think more carefully about movement in daily life.

About Jayze Lee
Jayze Lee didn’t grow up strong—he grew up sick.
Plagued by chronic bronchitis, he spent much of his childhood in hospitals, not playgrounds.
Everything changed the day his father brought him to the YMCA and said, “Try swimming—it might help you breathe better.”
That first swim lit a spark.
Movement became his medicine, and curiosity became his compass.
From sprinter to bodybuilder, from patient to practitioner, Jayze didn’t chase aesthetics—he chased answers:
Why do bodies break down?
Why does mobility fade?
This pursuit led him to formal training in both Medical Technology and Physical Therapy, grounding his work in clinical science.
Early in his career, he built one of the first rehab-integrated personal training clinics in Manila—working with high-performing clients, including executives and business leaders—before expanding internationally.
His defining chapter came in Hong Kong at Stretch Asia, where he delivered over 8,000 one-on-one assisted stretch sessions and rose into a leadership role in training and development.
There, he refined what would later become the STRH Method—a system focused on restoring joint range, improving stability, and rebuilding posture through precision, rhythm, and zero-force application.
After relocating to New York City, Jayze continued to evolve his work within the U.S. wellness and corporate fitness space, earning recognition for innovation in assisted stretch and mobility training.
Today, he is the founder of Ravel LLC, the creator of the STRH system, and the author of Stretch the Truth.
His work focuses on the modern, tech-driven body—where prolonged sitting, repetitive patterns, and poor movement habits accelerate decline.
Jayze didn’t just study recovery. He lived it.
And now, he helps others do the same.
Precision over pressure.
Repetition over force.
Truth over trend.
His philosophy is simple:
