The questions that come up most.

A way to consider training, sleep, food, planning and recovery together. It helps organise questions and practical choices, but it is not a diagnosis or validated health test. The full explanation is on the Approach page.

I help athletes organise habits around sleep, food, planning and recovery alongside their training schedule. Every agreement must fit the week they actually have. Training, medical care and individual nutrition advice remain with the appropriate professionals.

Not as a standalone product. If you have an external sports coach, I align with them so we don't work past each other. If you don't have one, we help you find a good one, or we integrate training in coherence with the rest of the plan, limited to endurance disciplines I'm comfortable with.

Yes. For specific questions (sports physician, physiotherapist, nutritionist, hormone expert) I work with a trusted network. If something comes up that falls outside my work, I refer you. No extra bills through me, just a direct referral.

Dedicated athletes between roughly 28 and 50 with a demanding job. People who run, play football, do Hyrox, prepare for a triathlon, next to a full-time life. You have a concrete athletic goal or a stubborn recovery pattern you want to move forward.

Yes. By far most people I work with are dedicated recreational or ambitious amateur athletes, not pros. The work is the same; only the context differs.

Absolutely. The principles work at any age. Above 50, different accents come into play: hormonal changes, recovery time, maintaining strength. I adjust the plan accordingly.

Yes, with attention to what differs. Cycle, perimenopause, hormonal dynamics after stopping the pill. These are all factors taken into account in the intake and the plan. For specific questions I work with additional experts.

If you expect me to coach you mentally in the psychological sense (anxiety, trauma work): that's not my work. If you have acute medical complaints: doctor first. If you don't want to change anything about your lifestyle and are only looking for a training schedule. If you expect 24/7 availability.

Yes. Calls, coaching and written plans are available in English. The online course and some materials are currently in Dutch. Mention it in the intro call and we'll look at what works for you.

Performance Analysis (€79): ten minutes of intake followed by a personal report with clear priorities, a four-week plan, audio explanation and one adjustment. No call.

Performance Plan (€895): a 75-minute intake and a twelve-week plan, with an evaluation after four weeks and a reflection at week eight.

Performance Program (€2,495): fourteen weeks of coaching, seven conversations, weekly adjustment and two reflection points.

There is no required sequence. The full overview is on the coaching page.

Depends on where you are and what you want. Not sure? Book an intro call. Twenty minutes, free. I'll give you honest advice on which option fits, or whether something else fits better.

Yes. An Analysis or a Plan is credited in full against the next step, provided you book within 60 days.

Yes. I'm self-employed, VAT-registered, and send a proper invoice you can submit as a business expense or under your employer's vitality budget.

A weekly contact moment, alternating between a 30 to 45 minute video call and a written or voice update. A deeper monthly review of 60 to 90 minutes. In between, short messages via a fixed channel, with a reply within 24 hours on working days. No 24/7 availability. This is structured coaching, not a hotline.

Not "homework" in the school sense. But in every session we agree on 1 to 3 concrete things you implement in the week after. Sometimes changing an evening routine, sometimes a nutrition pattern around training, sometimes tracking data systematically. Practical, and made to fit your actual week.

That's normal and part of the work. If you notice yourself sliding back, that's not failure. It's a signal we work with. It happens most often in weeks 5 to 7, when the initial energy fades and the real work begins. That's exactly what I'm there for.

An injury needs assessment and treatment by a physiotherapist, doctor or sports physician. We can discuss whether coaching pauses or adapts, but coaching does not diagnose or treat the injury.

Yes, in consultation. Short pauses (1 to 2 weeks) we solve informally. Longer pauses require rescheduling and possibly an extension of the program.

Almost everything online via Google Meet or Zoom, in English or Dutch. That works well for the nature of the work and gives you flexibility. Based in Barneveld, the Netherlands. In-person can be discussed for specific wishes.

A laptop or phone with a working camera and microphone, a stable internet connection and a quiet spot. Nothing else. No mandatory apps or devices. It does help if you use a sports watch or sleep tracker, because then we can work with that data.

For weekly asynchronous contact I use WhatsApp Business or email, your preference. Reply within 24 hours on working days. No weekend contact unless there is a race week or an acute situation.

Working days 8:00 to 10:00 and 19:00 to 20:30 (CET) for sessions. Outside those hours I respond to questions, but don't schedule sessions. Weekends I'm off. That's better for you too, because it helps you actually switch off.

Sometimes, for the Performance Program. I work with a maximum of 8 to 10 active programs at the same time to guarantee quality. Being on the waiting list costs nothing, and you get priority as soon as a spot opens up.

No. I don't give medical advice and don't make diagnoses. For medical complaints I refer you to your GP or a specialist. My work is lifestyle and performance focused, with respect for what belongs in the medical domain.

Do not send blood work for interpretation. Discuss medical test results with the professional who ordered them or another qualified healthcare professional. The privacy statement explains how other information you choose to share is handled.

Completely. Everything you share, from health data to sports data to personal context, is stored carefully and encrypted, and never shared without your explicit consent. Full explanation in the privacy statement (in Dutch).

No problem in principle. It is important that I know which medication, because some (cortisol medication, beta blockers, contraception) affect training and recovery patterns. When in doubt, always consult your treating doctor before implementing lifestyle changes.

By default, no. On request, yes, and useful for listening back. Always with your explicit consent. Recordings are kept for you only and deleted after 6 months, unless agreed otherwise.

For the Analysis via iDEAL or credit card at purchase. For the Plan and the Program in one payment or in three instalments, agreed in the intro call.

Performance Foundation: you may withdraw within the statutory withdrawal period as long as you have not opened the first lesson. Once you open the first lesson, no refund is available.
Plan: if the week-eight retest shows no difference in your score and no progress you recognise, the money goes back.
Program: after four weeks we take stock. Nothing changed in your experience and in your measurements, then we stop and I refund whatever has not been delivered.
Analysis: you receive a personal report with audio explanation and one adjustment after fourteen days.

Full terms in the terms and conditions (in Dutch).

By default, no. Some supplementary Dutch packages cover coaching or prevention programs. Check your policy. Some employers have a vitality budget that can partly fund a program.

Often yes, as business or professional expenses. Ask your accountant or tax advisor. I'm not a tax specialist and don't advise on this.
