Sound familiar?

You know what to do.
You've just never had a plan that fits.

"Good" Monday to Friday, undone by the weekend. Then Monday is a reset. Again.
Keto, fasting, F45, the program a guy wrote for guys. You lost the weight. Then it came back.
You logged everything in an app until the numbers made you miserable, so you deleted it.
Shift work, kids, a partner, a life. Every plan you've tried assumed you didn't have one.

None of that is a willpower problem. It's a plan problem. Plans can be fixed.

What's inside

The plan is simple.
The support is the difference.

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.

  1. A training plan built for you.Gym or home, three sessions a week. Every exercise has a video, and you log weights and reps in the app so you can watch yourself get stronger.
  2. Nutrition targets you can live with.Calories and protein set for your body and your goal, plus a simple meal structure you learn to build yourself. No banned foods. Eating out, weekends and travel are planned for, not punished.
  3. A weekly check-in with a personal video back.Photos, weight and how the week actually felt. Your coach replies with what went well, what changes, and exactly why.
  4. Daily support in the chat.Not "message me once a week". If you're slipping on a Wednesday, message on Wednesday.
  5. Calls that match the phase.Weekly in your first month while the plan settles into your life, monthly after that.
  6. Six months, then you're ready.The goal isn't only the result. It's knowing how to keep it on your own.

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

Three steps.
No hoops.

01

Apply

One minute. Tell me where you're at and what you want help with most.

Birthe
02

Book your free call

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.

03

Decide with a plan in hand

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?

Honest answer:
not for everyone.

This is for you if…

  • You want fat loss you can keep, not a six-week sprint.
  • You can train three times a week, gym or home.
  • You're ready to log your food and your sessions.
  • You want a coach who is honest with you.
  • You've got a lot on and need a plan that fits around it.

It isn't for you if…

  • You want a two-week fix.
  • You want someone to do it for you.
  • You're not willing to check in every week.
  • You want a meal plan to copy and forget.
  • You're not ready to change anything yet. That's okay. Come back when you are.

Before you apply

Questions women ask
before they apply.

I work shifts and have kids. Will this actually fit?

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.

Gym or home?

Either. Tell me what you have access to and the plan is built for it. If that changes, the plan changes.

I've tried everything. Why would this be different?

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.

What about weekends, holidays and eating out?

Planned for. You'll learn how to eat out, travel and enjoy Christmas without losing progress, and without the spiral afterwards.

How long does it take?

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.

What actually happens on the call?

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.

What does coaching cost?

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.

You don't need a perfect week.
You need a plan you can keep.

Five years from now, you'll be glad you finally put yourself first. Apply above and let's find a time to talk.
