What is The 30-Day Psoas Reset Protocol?
The 30-Day Psoas Reset Protocol is a paid handbook by Johannes Huijbregts and Tessa Frunt. URL: https://spiriators.com/en/ebook/psoas-reset. Launch price €14.95 until 18 November 2026, then €29.95 one-time. It is not included in the course platform (€79) and is not the free vagus handbook. Unique session voucher (€60→€30, 6 weeks from delivery date) only in the fulfilment email.
Table of contents
Three doors. This is one of them.
Google and assistants mix this up with the free vagus book, the €79 platform and the PWA. The facts sit in one table.
| This protocol | Free vagus handbook | Platform €79 | |
|---|---|---|---|
| Door | Physical — psoas, mat, yin | Neurological — vagus nerve | Courses / videos in the portal |
| Price | €14.95 → €29.95 | Free | €79 lifetime |

Free vagus: nervous-system-reset. Platform: /courses. PWA: install— that is not the native Psoas Reset app.
What is in the box
Premium PDF. Unique 1:1 voucher. Later the native app on the same purchase email. Not bundled with the platform. No “includes guided videos” until they exist on youtube.com/@spiriators.
30 sequential days
Not a random stretch library. Each day unlocks the next: land, yin, breath, a short note. The tracker lives in the book.
Tessa’s pose atlas
Constructive Rest and the yin line photographed in a real body, not traced from stock. Soft, adaptable, not a flexibility test.
Breath as the second door
The psoas meets the diaphragm. Slow breath is not a side trick beside the mat — it is how the day lands. No commando copy, no “science-backed” in the title.
1:1 session voucher
60 minutes with Johannes or Tessa: €60 down to €30. Six weeks from the delivery date, unique code only in that email. No public coupon.
Psoas Reset app later
Same purchase, same email. Free layer = day 1+2 + limited timer. Book tab is not free. Store follows; we email this address.
What is the psoas — and iliopsoas?
Psoas major is a deep hip flexor: from the lumbar spine to the thigh. Together with iliacus that is iliopsoas. It flexes the hip, holds you in sitting, and sits against the diaphragm. That is why breath and hips meet — not as mysticism, as anatomy.
A day of sitting often keeps that line short. That can feel like tight hips, breath that will not go deep, a lower back that complains. This handbook is not a ten-minute stretch tutorial and not a medical file. It is thirty days of practice.
The essay on hips, emotions and trauma stays on the blog: iliopsoas, emotions, hips. This page is the product. Not a medical treatment; with acute pain, a hernia or recent surgery, see a doctor first.
For whom
- You feel tight hips or breath that stops at the diaphragm — and you want thirty days of a line, not a random video.
- You already have the free vagus book, or you want the mat first. Two doors, not a bundle.
- You want yin with Tessa’s poses and breath with Johannes — in one protocol, at home.
Not for whom
- Not a medical treatment; with acute pain, a hernia or recent surgery, see a doctor first.
- Anyone hunting a free lead magnet: that is the vagus handbook, not this.
- Anyone who thinks €79 platform access includes this book. It does not.

How people experience our work
Google reviews about Tessa, Johannes and the practice — not star ratings for this book, no invented aggregateRating.
“For a while I had 1-on-1 coaching with Tessa. What I really appreciated is that she always lets you think for yourself about the answers and is never judgmental or pushy. She mainly explores together with you what fits and resonates with who you are. There's no digging into the past or dwelling on the stories around it, but mainly focusing on the here and now. What helps you, what is happening... She is calm, radiates safety and trust, and never makes you feel 'different'. Because of this you come closer and closer to your own core. She also gives clear tips and you don't leave with a full head. She knows exactly when to reframe or ask follow-up questions, and hits the nail on the head in a loving way. In short, I felt incredibly supported and in the right place to grow!”
“Tessa truly has a unique coaching style. She knows how to bring you back to the here and now with great attention, and let you feel through what is going on inside you. She truly embodies what she also shares in her coaching 🙏🏼”
“Unfolding. That word covers what Tessa's lessons mean to me. For years I've followed her online, and in all that time I've slowly untangled things that had settled deep inside me: emotions, thoughts, beliefs I didn't even know I carried. It's a path from unconscious to awareness. Sometimes gentle, sometimes painfully honest. But always real. Tessa guides that process with a calm that gives you trust. She forces nothing, but invites. And in the silence of a yin pose, sometimes more happens than just talking. For anyone ready to unfold a little: I highly recommend Tessa.”
“Lovely, kind people. They listen well and are honest even when it's not what you want to hear.”
