Move Better. Get Stronger. Feel Better.
Personalized movement and strength coaching for people who are tired of hurting, feeling limited, or being told to just live with it.
We figure out what’s limiting you, work on it together, and build from there.
Every session has a reason.
We’re not following a preset workout calendar. Each appointment builds on what we learned from the last one. We assess, make a change, see how you respond, and use that information to decide what comes next.
Understand
Assess
Discuss your history, what you have already tried, and what you want to get back to. Look at movement, muscle function, strength, and control.
Identify
Look for movement limitations and compensation patterns to explore. Set a specific priority based on what we observe.
Change
Activate
Use neuromuscular work—targeted muscle activation and movement work—to address those priorities, rather than starting with a standard workout.
Retest
Repeat the movement or muscle-function check. Compare comfort, range of motion, strength, or control to see how your body responds.
Learn
Practice
Try the individualized practice created during your appointment. Notice how movements feel between visits.
Feedback
Tell us what changed between appointments: what improved, what felt difficult, and what still is not working.
Build
Adjust
Use your feedback and today's assessment to revisit anything that needs attention and change the plan where needed.
Progress
Build on what is working toward the strength, confidence, capacity, and activities that matter to you. Each appointment builds on the last.
Every appointment gives us information that shapes the next one.
Practice between sessions. Bring your feedback back.
You don’t have to master your homework before you come back.
Your individualized practice is created during your appointment. Spend some time with it and notice what happens. You might feel better, a movement might feel easier or harder, or you might notice no change at all. All of that gives us useful information when you come back.
Why we typically start weekly
We typically start with weekly sessions so we can make a change, see how you respond, and adjust sooner. It’s a shorter feedback loop, not a fixed requirement. As you become more independent and need less hands-on adjustment, appointments can be spaced out. Weekly isn’t necessarily forever.
This is movement and muscle-function work, not medical diagnosis or treatment; it is not a substitute for medical care. We work within your medical team's guidance when needed.
Meet Jeremiah Stilwell
Jeremiah works one-to-one with clients of different ages across Humboldt County, from younger adults returning after injury or surgery to athletes and older adults who want to stay strong, capable, and independent.
You’ve tried things. Let’s figure out what’s next.
If you’ve tried physical therapy, chiropractic care, massage, exercise, or other approaches and you’re still dealing with limitations, that doesn’t necessarily mean you need to try something completely different. We look at movement and neuromuscular function, make a targeted change, and retest how you respond.
Movement and strength coaching can complement your other care; it does not replace medical diagnosis or treatment.
Jeremiah is a Certified Muscle System Specialist. The Muscle System Specialist (MSS) methodology supports his assessment, neuromuscular work (targeted muscle activation and movement work), and retesting. Serving Arcata and Humboldt County since 2013.
What brings you to Stilwell?
- I want to get stronger and fitter
- I'm dealing with pain
- I'm recovering from an injury
- I'm preparing for or recovering from surgery
From first conversation to ongoing sessions
The two free consultations help us decide whether the approach fits. The comprehensive assessment is a separate, paid appointment.
Free 15-minute phone consultation
An introductory conversation about your concerns and goals to see whether Stilwell may be a good fit.
Free in-person consultation · About one hour
Meet Jeremiah at the Arcata studio, discuss your situation in more detail, and decide whether moving forward makes sense. This is not the comprehensive assessment.
Comprehensive assessment · $250
A separate, paid assessment of movement, muscle function, neuromuscular control, and limitations. Complete a health-history questionnaire beforehand; receive a written report and personalized Blueprint.
Individualized sessions · $145 per hour
Build on your assessment with targeted neuromuscular activation, retesting, home programming, feedback, and progressive strength training.
More than feeling better for one appointment
- Move with more comfort and control
- Build strength and physical capacity
- Feel more confident in your body
- Return to activities you enjoy
- Stay capable and independent as you age
These are goals we work toward, not guaranteed results. Your starting point, response, and feedback shape the progression.

Frequently asked questions
How is this different from following a workout plan?
We assess movement and muscle function, use neuromuscular work—targeted muscle activation and movement work—and retest your response. Your individualized practice is created during the appointment; what you notice between visits helps guide the next one. Each appointment gives us information, not just a completed workout. Jeremiah's Muscle System Specialist (MSS) methodology supports this process.
Do I need to already be in shape or pain-free to work with you?
No. An injury you still have, a surgery you are coming back from, or a problem that has been around for years is a normal place to begin. We also work with people who already train and want more strength, control, or performance. If a medical provider needs to clear you first, we say so.
What happens at the first appointment?
Start with a free 15-minute phone consultation, then a free in-person consultation of about an hour if we are a fit. Neither includes the comprehensive assessment. If you choose to move forward, the separate assessment costs $250. Complete a health-history questionnaire beforehand; Jeremiah reviews it and asks targeted follow-up questions. The assessment examines movement, muscle function, neuromuscular control, and limitations. You receive a written report and personalized Blueprint. Individualized sessions are $145 per hour, building on those findings with neuromuscular activation, retesting, home programming, feedback, and progressive training. Responses vary; immediate improvement is not promised.
Where are you located and who do you serve?
We are located at 475 5th Street, Arcata, CA 95521. We serve clients from Arcata, Eureka, McKinleyville, Fortuna, and throughout Humboldt County. Free parking is available.
Do you offer a free consultation?
Yes. Start with a free 15-minute phone consultation. If our approach is a fit, your in-person consultation at the Arcata studio is also free and takes about an hour. These introductory conversations do not include the separate $250 comprehensive assessment. Individualized sessions are $145 per hour if you choose to continue. Call (707) 798-0512 or request a conversation through the form. No obligation.
How does this work alongside physical therapy or chiropractic care?
Different professionals have different specialties. Our focus is movement and strength coaching: assessment, neuromuscular work (targeted muscle activation and movement work), retesting, and practice informed by your feedback. This can complement other care; it is not medical diagnosis or treatment and does not replace your medical team.
