Who we are
AER on Newbury
The idea
aer is Latin for air. Every restoration begins with a breath.
AER on Newbury is a Certified Postural Restoration Center in Back Bay, Boston. We train the body as one integrated system — respiratory mechanics, neurological position, autonomic regulation, and progressive resistance — because it is one system.
Most training programs start with a muscle. We start with a position: where your ribcage sits, how your diaphragm moves, what your nervous system is doing before you touch a weight. That position determines whether the training you do produces the adaptation you trained for.
Position determines function. We don't train muscles in isolation — we restore the system that lets training work.
The framework
Our clinical foundation is Postural Restoration — a decades-refined framework developed by the Postural Restoration Institute that integrates respiratory science, neurology, and biomechanics into a coherent system.
PRI is the framework. What we build on it — integrating progressive resistance training, autonomic monitoring, and cross-disciplinary evidence — is the practice. We call it the Pneuma Protocol.
Who this is for
Two kinds of people tend to find us:
People who have been everywhere — doctors, specialists, therapists — and nobody has connected the dots. Dysautonomia, idiopathic pain, visual disturbances, chronic conditions that don't fit a single specialty. We don't diagnose disease. We look at the whole pattern and ask what the body is doing and why.
And people who are doing everything right — training hard, eating well, recovering well — and hitting a ceiling they can't explain. Not because their program is wrong, but because the position underneath it isn't ready to receive the load.
Both groups share one thing: they're past the point where surface-level answers help.
The standard
Everything we publish — every Field Note, every post, every claim — follows a simple rule: it has to hold up. Claims based on peer-reviewed research are cited with honest limitations stated. Claims that describe our clinical framework are flagged as exactly that: a coherent, decades-refined clinical framework, not a conclusion from a peer-reviewed trial. We don't overclaim, and we don't ask you to take our word for it.
The team
Who you'll work with.
Peter Jang
MFA, CSCS, PRT · Founder
Peter founded AER on Newbury to build the kind of practice that didn't exist yet — one where strength and conditioning, respiratory science, and neurological position aren't separate disciplines but parts of the same conversation.
He's completed the full Postural Restoration Institute curriculum across all three tiers — Primary, Secondary, and Tertiary — and is Postural Restoration Trained. That framework is the foundation. What he builds on it — integrating progressive resistance, autonomic monitoring, and cross-disciplinary evidence — is the practice.
Before AER, Peter earned an MFA — a background that trained him to read narrative, and the body tells one. Strength coaching came from a different place entirely: a lifelong obsession with what peak human performance actually looks like. The CSCS was the credential; the drive was always pushing the ceiling. Both threads shape how he works now: always asking why the body is doing what it's doing, not just what to do about it.
Karen Taylor-Soiles
PT, MA, PRC
Karen brings over two decades of clinical experience to AER — the kind that comes from treating the cases nobody else could figure out. Orthopedic, neurological, vestibular, chronic pain — she's worked across all of it, and the throughline has always been the same: look at the whole system, not just the part that hurts.
She earned her physical therapy degree from Northeastern and a master's in Motor Learning from Columbia, then built a career grounded in understanding how the body learns to move — not just how to make it stronger. That's the lens she brings to every session: motor learning, not just motor output.
Karen is a PRI Certified conference presenter — selected by the Institute to present their material to clinicians at PRI conferences. She's also fluent in French and Greek — which tells you something about how she approaches complexity: she doesn't avoid it, she learns the language.
At AER, Karen specializes in the cases that sit at the intersection of multiple systems — pain that has a postural driver, movement dysfunction with a neurological root, recovery that stalls because nobody addressed the position underneath the pattern.
