For people who sit all day and still want to train

Your lower back has been covering for the rest of you.

For people 35 to 50 with a desk job who train around back pain, or stopped because of it. I find what your back has been compensating for and build your training around it. In person in Luxembourg or online.

The Cycle

What you’ve already tried

You’ve tried the sensible things.

A gym membership you used seven times. A personal trainer at €80 a session until quarter-end landed and you never rebooked. The stretching routine from a video. A few physio appointments that settled it for a month.

Each one dealt with the spot that hurt. Nobody tested the rest of you, so the same tweak came back a few months later.

Root Cause

Why it keeps coming back

Every movement needs your whole body to do its share. Ten hours of sitting stiffens your hips and stops your mid-back rotating.

When that happens, something nearby picks up the work, and very often it’s your lower back.

It covers for months. Then one Tuesday you bend down for a bag and it lets you know.

The way out starts with finding which part stopped doing its job.

Free · The 12-Minute Back Check

The 12-minute check that shows what your back has been covering for

These are the six self-tests I use with every client, done left side against right. It takes ten minutes on the floor and two minutes on the scorecard.

You’ll see where your body is weaker, which side is doing more of the work, and what to train first.

Each test comes with a short video so you can follow along.

Proven Results

What they say

Martijn van der Schaaf

Private Equity / Ex-EQT

"I lost substantial weight and volume, and feel more energized than ever. I even played 36 holes of golf in one day with zero back pain — something I couldn't dream of a year ago."

Laurent Goyer

Private Capital Lawyer (Quebec, Luxembourg, Paris)

"After a few weeks, I had more energy, better focus, and more patience at home. I feel like myself again: stronger, calmer, and in control."

Nicolas Boatwright

Head of Partnerships & Alliances Europe, Infosys Finacle

"Practical, focused, and designed for busy professionals who need systems that actually fit real life."

Client Profile

Who this is for

You’re somewhere between 35 and 50. You sit most of the day. You’ve trained for years, on and off.

Your lower back tweaks every few months. Either you train around it, skipping deadlifts and keeping everything light, or you’ve stopped and the gym bag has been in the boot of the car for weeks.

You can follow a programme on your own. You need someone to look at your body, find what’s driving the pain, and build the programme around that.

The Real Impact

What it costs

Pain changes your week long before you admit it.

Sleep slips. Patience thins. You think twice before picking up your kids. By Friday you’re running on coffee.

Your family and your team usually notice first.

The Framework

How the coaching works

It starts with an assessment. You film a set of movement tests at home, and I look at your range, your strength on each side and how you move under load. That shows the pattern behind the pain.

Then come three blocks of training, with a reassessment between each one:

Reset

Low-threat training that settles things down and builds a base you trust.

Rebuild

Strength through fuller range, on both sides, in every direction.

Rise

Power, speed and conditioning, so you can keep training the way you want for the next twenty years.

Alvin Sicre

I spent 18 years at a desk in London and Luxembourg financial services, the last stretch as head of compliance at a private equity firm[cite: 1]. My back tweaked every few months, and I trained around it the same way most of my clients did[cite: 1].

What changed was testing where my body was weaker[cite: 1].

I now coach a small number of people with desk jobs to train without back pain hanging over every session[cite: 1]. I’m a coach trained in the RebuildR method, which builds capacity around pain[cite: 1]. If something needs a clinician, I’ll tell you and point you to one[cite: 1].

Options

Ways to work with me

Every coaching option starts with the same assessment and follows the same three blocks: Reset, Rebuild and Rise. What changes is how often we’re in the same room.

In person

Luxembourg

We train together in Luxembourg. I watch every rep, adjust on the spot and progress you week by week. This suits you if you want hands-on coaching and live or work in Luxembourg.

Hybrid

In-Person & App

We meet in person for your assessment and at key points in each block. You train the rest of the week on your own with the programme in the app. I review your filmed sessions and adjust as you go. This suits you if you live in Luxembourg and can train on your own but still want someone watching you lift from time to time.

Online

Global

You film your assessment at home and I send back your analysis and your first week within 72 hours. After that you get a call every two weeks, feedback on your weekly check-in and messaging in between. This works from anywhere, in English or French.

All three run for a minimum of 12 weeks. Places are limited.
