Optimising cognitive performance through physical training

Quarbon designs physical training programmes for high-cognitive-load teams (R&D, deeptech, engineering), with a precise goal: supporting attention, clarity and mental endurance, with measurements to back it up. Not generic wellness.

Intellectual performance is prepared physically.
The approach

Intellectual performance is physiological.

In high-cognitive-load professions, the quality of decisions depends partly on the physical condition of those who make them. Properly programmed, training remains an often-underestimated lever of cognitive performance.

01

Train the body that thinks

Clarity, attention and mental endurance also rest on a physical base. It is trained methodically, like strength or endurance.

02

Fit into the team's week

The schedule is the number-one constraint. The service is embedded: one short session per week, at your offices, without overloading the working week.

For your teams

At the core of Quarbon: your teams

Group training sessions, embedded in the working week of high-cognitive-load teams, in R&D, deeptech and engineering. The goal: sustaining their cognitive performance over time, and measuring it. Results rest on objective testing, not just on what's self-reported.

Entry point · 90 min

Discovery workshop

A 90-minute session, with no free weights, to let your teams experience the link between physical condition and intellectual performance, through practice and through data. A half-day format is also available.

Embedded service · subscription

Continuous preparation

A renewable subscription: a one-quarter priming phase (one short session per week, progressive intensity), then renewal into continuous follow-up. A coached framework, with measured progression.

Fundamental patterns, trained methodically.
The method

A simple frame, constant and progressive

Quarbon uses training as a physiological tool, in service of cognitive performance: no nutrition, no life coaching. The same method structures every coached programme, individual and collective alike.

Step 01
Strength-training fundamentals

Introduction to the fundamentals: posture, bracing and clean execution of the basic movements.

Step 02 · Testing
Fundamental patterns

Testing the fundamental patterns: squat, Romanian deadlift (RDL), push-ups, rows.

Step 03 · 30 min
Targeted training

Targeted work to develop these capacities, under progressive and supervised load.

Step 04 · 20 to 30 min
Adapted conditioning

Conditioning adapted to each person's level, as AMRAP, EMOM or HIIT.

This frame describes the coached programme. The 90-minute discovery workshop is a lighter version of it, with no free weights.

Project status

A project in the making

Quarbon is an entrepreneurial project supported by Université Paris-Saclay. The protocol is in its use-case and scientific-validation phase, ahead of deployment with high-cognitive-load teams. Here is where the project stands.

  1. Phase 01Done

    A formalised method

    A frame built on 7+ years of individual and group coaching: 70+ profiles coached, hundreds of people in group classes.

  2. Phase 02In progress

    Use cases, varied audiences

    The protocol is applied and measured with varied audiences, one-to-one and in groups, to test its frame and its markers.

  3. Phase 03In progress

    Scientific validation

    The validation process for the protocol is under way. Until it concludes, the results shown on this site remain field observations, not established evidence.

Field observations

Before being deployed with teams, the method was built in the field, with varied audiences. Below are the trends observed across 21 documented one-to-one programmes, over 12 to 24 months and beyond: real trajectories, not yet scientific conclusions.

Strength

Fundamental patterns

Marked progression on the squat, the RDL and rows, over 12 to 24 months of regular coaching.

Endurance

Aerobic capacity

Improved endurance and a lower resting heart rate observed over time.

21 cases

Documented

A portfolio of varied profiles, measured on agreed markers, from beginner to advanced.

Representative profiles

R&D leadership 1.5 h / week

A very tight leadership schedule. A full-body programme centred on the fundamental patterns reached intermediate strength standards by maximising every minute of training.

Executive · analytical profile Clean recomposition

5 h/week, advanced periodisation across several cycles. A high-level body recomposition and continuous progression, over more than 18 months of follow-up.

Higher-education academic Performance & upkeep

A saturated schedule, ~2 h/week plus weighted running. A maintenance-and-performance goal: working loads and endurance in continuous progression.

Tech profile · highly sedentary role Beginner gains

A sedentary profile, a programme centred on six fundamental patterns. Strong progression of working loads from the first sessions, which builds a technical base.

About

The human behind Quarbon

It was in 2017, amid the intensity of audit work, that I understood something simple: intellectual performance doesn't hold without a physical base. The long days, the constant mental load, the concentration demanded without let-up: all of it rests on a physiological infrastructure we almost always neglect.

That realisation is what shifted my path, from finance toward physical preparation. Since then I have coached 70+ individuals (university professors at top engineering schools, executives, researchers, high-level amateur athletes) and led groups: Volleyball at Nationale 3 level, group classes and training for hundreds of people, including 40+ in monitored sessions.

Today I am building Quarbon, an entrepreneurial project supported by Université Paris-Saclay (Pépite PEIPS programme), alongside the first year of my Master's in Sport Sciences for Health & Performance at the same university. The protocol is undergoing scientific validation; individual coaching remains my field laboratory.
