Sound familiar?
None of that is a willpower problem. It's a plan problem. Plans can be fixed.
What's inside
A routine says train at 6am every day and eat this for lunch. A system says three sessions a week, slotted in wherever your week allows. You get a system.
Results
Busy women with jobs, kids and a lot on. Different starting points, same story: already doing the work, not seeing it in the mirror, until the plan fit.

Your coach
Birthe Sagstad
Co-founder and head coach for women, Onyxia
I trained for years with no clear plan, so I know what spinning your wheels feels like. Then I got a coach myself and it clicked: it isn't that hard once the right system is in place. I finished my civil engineering degree, then went all in on coaching instead.
I work with women in their late 20s to 40s who have a lot on and have been burned before: by crash diets, by group training, by programs written for men.
I'm kind, and I'm straight with you. Empathy alone hasn't worked for you, and neither has being yelled at. You get both: the compassion, and the truth about what it will actually take.
You get a plan made for you, not a template with your name on it, and I keep my client list small so I can be properly hands-on.
By the end, you won't need me. That's the point.
How it works
One minute. Tell me where you're at and what you want help with most.
As soon as you apply, my calendar opens. Pick a 30-minute slot. On the call I map out exactly what I'd do in your shoes with your training and food, and you keep that plan either way.
If working together makes sense after the call, we talk about it. If not, no stress: you still leave knowing exactly what to change.
Is this for you?
Before you apply
That describes most of my clients. Sessions are built around your roster, meals around your real week. When life changes, the plan changes with it, instead of you falling off it.
Either. Tell me what you have access to and the plan is built for it. If that changes, the plan changes.
Because it isn't another program or another set of rules. It's a system built around your week: sessions you slot in where they fit, meals you learn to build yourself, and a coach who checks every week that it's working. Most "failures" were plans that never fit in the first place.
Planned for. You'll learn how to eat out, travel and enjoy Christmas without losing progress, and without the spiral afterwards.
We work together for six months. Most women see clear changes in the first 8 to 12 weeks. The rest is about making it stick so you never need to start over.
Thirty minutes on Google Meet. I look at what you've been doing, then map out exactly what I'd do in your shoes with your training and food. You keep that plan either way. It costs nothing and there's nothing to sign up to.
The call is free. Coaching is an investment in a real coach, not an app, and I'll walk you through it on the call once I know your goal and what you need. No pressure either way.
Five years from now, you'll be glad you finally put yourself first. Apply above and let's find a time to talk.
