Etzain Santamaria, ACSM Certified Exercise Physiologist, smiling in the Sound Movement studio

Meet your coach

Hi, I'm Etzain.

I'm an ACSM Certified Exercise Physiologist. I started Sound Movement after moving from Arizona to Seattle, and I combine exercise physiology, behavior-change science, and practical movement strategies to build programs that work with your life, not against it.

My focus is functional strength, mobility, and injury rehab, with coaching that is supportive, practical, and rooted in evidence. The goal is simple: help you create momentum and keep it.

In their words

"Etzain is very knowledgeable, detail oriented and a positive coach. We have set clear goals and have mapped out the steps and timeline required to achieve them… The equipment is high quality and the studio provides plenty of room for a multifaceted workout."
Steve S. · Google review
"He researched the gold standard study (ONERO/LIFTMOR) to incorporate appropriate exercises… Etzain is a gift and anyone who chooses to work with him, lucky… and eventually, more physically fit and stronger!"
Linda W. · Google review
"Even when I encountered an unexpected health issue that impacted my mobility, Etzain didn't miss a beat. He pivoted our workouts to complement my physical therapy treatments… I leave each session feeling better about myself."
Laura M. · Google review
"I've been training with Etzain since the summer and just renewed again. What sets him apart is how much he focuses on my needs — nothing about the programming is rigid… Worth every penny."

Common questions

Do session packs expire?

No. Packs never expire, so you can train at whatever pace fits your life.

What's the difference between a pack and a membership?

A pack is paid upfront and used whenever you like; bigger packs lower your per-session rate. A membership is billed monthly at $80 per session based on how often you train each week, with no large upfront payment.

I'm new to exercise, or coming back after an injury. Is this for me?

Yes. Sessions are built around your history and current ability, and adjusted as you go. Mobility and injury rehab are core specialties.

What happens in the first session?

Most clients start with a 75-minute Initial Assessment + Movement Screen ($100): a movement assessment, strength, mobility and injury-risk screening, a goal discussion, and a clear action plan with recommendations.

What is your cancellation policy?

Please cancel or reschedule at least one day (24 hours) before your appointment.
