Adirom was built around a single conviction: lasting physical progress requires a coherent plan, not an intense moment.

The studio opened in Brussels' Saint-Gilles neighbourhood in 2016, occupying a ground-floor space on Rue du Page. The decision to work from a fixed location, rather than moving between commercial gyms, was deliberate. A stable environment allows for consistent assessment conditions, a maintained equipment inventory, and a sustained coaching relationship with each client.

Before establishing Adirom, the studio's lead coach spent six years working across fitness facilities in Brussels and Ghent, accumulating a direct record of what works in long-term individual programming and what does not. The patterns observed during that period — in particular the difference in sustained progress between clients with structured plans and those without — formed the basis of Adirom's operating methodology.

The studio holds NASM (National Academy of Sports Performance) and National Strength and Conditioning Association (NSCA) certifications, alongside ongoing continuing professional development. Practice is fully insured under Belgian regulations for fitness and wellness professionals.

“A training log that accurately reflects a person's capacity and adapts to it over time is a more useful instrument than any single session, however demanding.”

Marc Delrue

Lead Coach & Studio Founder

Marc has worked in structured fitness coaching since 2010, accumulating experience across one-to-one sessions, group training, endurance preparation and sports-specific conditioning. He holds dual certification from NASM and NSCA, and has completed advanced coursework in movement screening and body composition assessment.

His coaching philosophy centres on the primacy of the programme over the session. Each client arrives with a periodised plan written specifically for their current capacity, their available training schedule, and the performance markers they have identified. The session delivers the plan's programmed work; the plan itself is revised at regular check-in intervals based on documented progress data.

Outside the studio, Marc maintains his professional knowledge through continuing education, including regular attendance at strength and conditioning symposia and ongoing engagement with published research in exercise science and nutritional planning.

04  /  Operating Principles

Assessment Before Programming

No training plan is written before a movement screening and goal-setting conversation have taken place. The assessment informs every subsequent programming decision.

Data-Guided Revision

Plans are reviewed against the training log at each progress check-in. Adjustments follow what the data shows, not subjective impressions of how a period of training felt.

Long-Term Load Management

Every programme includes structured active recovery phases. Managing cumulative load across a training block is regarded as essential to sustained progress, not optional.

Ongoing Coaching Relationship

The coaching relationship extends beyond the session. Clients have direct access for questions on programme execution, nutrition awareness and rest-day planning.

Evidence-Informed Practice

Programming decisions are grounded in published exercise science. Novel approaches are introduced only when their basis in peer-reviewed research is clear and applicable to the client context.

Insured & Accredited

The studio maintains full professional liability insurance and adheres to accreditation requirements for fitness professionals practising in Belgium. Certifications are kept current through continuing professional development.

05  /  Client Notes

“The periodised plan was a genuine shift from how I had been approaching training. Having a written programme with clear weekly objectives — and someone to review it with — made all the difference to how consistently I showed up.”

J. Vanderberg — Brussels, 2024

“Marc's approach is methodical without being rigid. He explains the reasoning behind each programme block, which makes it far easier to maintain motivation when progress is incremental rather than dramatic.”

A. Leclercq — Ixelles, 2024
