Through years of personal exploration, I've built a practice around gymnastics-inspired movement, disciplined flexibility work, and deliberate nutrition habits — and I document every step of it here, honestly and in detail.
I'm Sivers Kittelson. I began writing this blog not because I had answers, but because I had questions — and a growing sense that the mainstream conversation about fitness was missing something fundamental about how the body actually wants to move.
What started as a personal notebook became, over nine years, a fairly detailed record of how I transformed my relationship with movement. I borrowed from competitive gymnastics training, from martial arts warm-up traditions, from slow yoga practice, and from a much more attentive approach to eating. I tested things, dropped what didn't work, and kept what did.
The result is a practice I call my own — not a system, not a programme, not a product. Just the most honest account I can give of what has genuinely shifted things for me. Take from it whatever is useful.
Three interconnected principles shape every routine, every article, and every session I offer. Remove any one of them and the whole thing becomes something different.
I was drawn to gymnastics preparation not for performance, but because it develops a quality of movement awareness that no other discipline quite matches. The body learns to move as a coherent whole — weight transfers, joint stacking, spatial orientation. These skills translate into everything else.
I approach flexibility the way a careful investor approaches capital: slowly, patiently, with a long horizon. The returns are real and cumulative, but they refuse to be rushed. Every routine I share is designed around this reality — consistent work over weeks and months, not dramatic results overnight.
Over the years I've become increasingly attentive to how what I eat interacts with how I feel during and after movement. My approach isn't prescriptive — it's observational and practical. I share what I've noticed in myself, and invite readers to run their own experiments rather than follow my conclusions.
Three ways to engage with the practice beyond the free blog content — each designed for a different level of commitment and personalisation.
A thorough, illustrated compendium of my personal practice — nine years condensed into a clear, structured guide designed for independent daily use.
A single 60-minute video conversation structured around your specific situation — where I listen, share what's been relevant in my own practice, and leave you with clear next steps.
A sustained monthly engagement for those who want a committed companion through the long, gradual work of building a genuine flexibility and mobility practice.
Words from people who have spent time with the blog or worked with me in a personal capacity over the years.
The Practice Field Guide changed how I approach the whole subject. Sivers doesn't try to be your coach — he tries to make you a better observer of your own body. After two months with the guide, my morning routine is quieter and more purposeful than it's ever been.
What struck me most about the Focused Dialogue was how carefully Sivers listened before saying anything. He didn't arrive with a ready-made answer — he genuinely engaged with my particular situation. The suggestions I came away with were specific and immediately actionable.
Seven months into the Ongoing Practice and it has become the most stable part of my week. The sequences evolve with me — nothing ever feels stale or repetitive. And the nutrition conversations, which I was initially sceptical about, have genuinely changed how I think about eating in relation to movement.
In-person sessions take place at my Eindhoven studio. Please arrange an appointment before visiting — no walk-ins.
