Psoas Keep
Keep your psoas & hips soft daily
Short psoas exercises in a rotatable carousel — Yin and Yang — organised into Psoas, Lower Back, Hips and Flanks. For when stiff hips or a tight lower back ask for attention.
At your pace: start with the exercise you want. Swap an exercise if it doesn’t fit that day, and create your own carousel in ‘My Yin or Yang’. After Yang exercises, note how your back and hips feel, and get a recommended Yin carousel for the evening.
Psoas Keep is about keeping the body soft and giving short moments of attention. You’ll also find a Breath reset in the app, with three breath timers for deeper ease.
The Psoas Keep exercises come from movement analyses of what the function is, and which posture best preserves that function. All exercises were filmed and explained by Tessa herself in instruction videos.

Fit
Who it's for — and when not
A fit if
- Anyone who wants daily psoas exercises
- Anyone with stiff hips, lower-back pain or breath that stays high — who wants short sessions for that
- Anyone who wants to stay soft after the protocol — or start at their own rhythm
Rather not
- Acute pain, a hernia or recent surgery — see a doctor first
- Anyone with chronic tension in the hips or back — start first with the Psoas Reset Protocol
- Anyone expecting a “released” psoas after one session
Complementary
Fits after the 30-day protocol
The Reset Protocol is thirty days of structure with handbook, app and session voucher. Keep is the daily line to stay soft — or to practise at your own rhythm right away.

Quotes from our work with yin, breath and psoas — no medical claims.
“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.”
