From doubt to confidence in your training and nutrition.

Coaching that makes you stronger - even without me.

This way people also know that’s what I really help with.
Maybe change that for Helping you build a leaner, stronger body - by understanding what actually works.

You’re not stuck because you lack effort.

You’re stuck because you don’t know

what actually drives results.

  • You train, but your body barely changes
  • You second-guess your training and food choices
  • You put in effort, but aren’t sure its the right effort.

“You’re trying to do the right things, but
you’re not sure what that actually is”

You follow random plans, tips, and advice. But without understanding why, your body never really changes.

It’s about understanding and implementing what drives real, visible results - for your body.

It’s time for your effort to start working in your favour Sustayn isn’t about doing more or being stricter.

Sustayn turns effort into results.

The Sustayn Method

This isn’t about following a plan.

It’s about understanding why the plan works

and how to apply it long-term.
Step 1

Insight

We clearly map out where you are right now.

Why your body isn’t showing what you want yet, and what’s needed to change that.
Step 2

Structure

Based on those insights, we build a clear structure for your training and nutrition.

An approach that fits your goals and the life you live.
Step 3

Understanding

With monthly check-ins and data tracking, we refine what works and adjust where needed.
You learn exactly which choices influence your results
Step 4

Confidence

You understand what works for you.

You’ve built a lifestyle that delivers results.

And you’re able to maintain it independently.

“I don’t give you a fish,

I teach you how to fish”

You don’t become dependent.

You become confident.

What people notice over time.

The feedback I receive is rarely about motivation or intensity.

It’s about clarity, structure, and confidence.

Three months ago, I started a coaching program with Tim. My goals were to eliminate numerous cravings, reduce my snacking, stop constantly thinking about food, and lose a few pounds.
Two years ago, I followed an online program that didn't help me. In fact, it was counterproductive.
Now, after three months of coaching with Tim, I've already achieved most of my goals. Read More...

After years of struggling with myself and myself regarding nutrition, I started looking for someone whocould help me achieve my goal: developing a healthy and balanced lifestyle.

The bigger goal: building a body that reflects that same lifestyle. Mens sana in corpore sano. Not onlycreating a healthy relationship with food, but also seeing it reflected in my physique. Read More...

Last year I followed a coaching trajectory with Tim with the aim of building muscle mass. Thanks to Tim's guidance and knowledge, I was definitely able to achieve my physical goals and made a lot of progress.

Tim really takes the time to listen to what you want and what your goals are.

Where I thought that I would be there with just a training schedule made by a professional. Read More...

The collaboration

I work month to month.

No 6 or 12 month contracts.

What’s always included:
  • A personal training plan aligned with your goals

  • Practical tools after every contact moment

  • WhatsApp support

  • Access to the Sustayn Method starter course
  • A meal framework as a foundation
Each month, we choose:
  • 2 contact moments

  • or 4 contact moments

A contact moment can be:
  • A coaching session (nutrition & lifestyle)

  • A training session to better understand your workouts

Every month we look at Where are you right now? What do you need to move forward? The goal is understanding what works, and being able to apply it independently. Inside and outside the gym.
