Human Performance Strategist · Strength & Conditioning Coach — Paris / Remote

Physiology in service of your thinking capacity

Your decisions depend directly on your recovery capacity. I design hybrid performance strategies — health, physical, cognitive — for high-cognitive-load professionals.

Philosophy

Performance is physiological.

In high-cognitive-load professions, your recovery capacity directly conditions your lucidity. Properly programmed exercise is the most underestimated lever.

Observation 01

Failing recovery

Physiological depletion alters judgement long before fatigue is consciously felt. Low HRV, elevated RHR, fragmented sleep: the signals exist before the symptoms.

Observation 02

The time available

Your schedule is your primary constraint. My protocol fits within it without overloading it, by maximising the physiological gain of every minute of training.

Strength training, focused effort
Find the balance between data and your lived experience.
The Approach

A protocol grounded in physiology

My expertise is focused on training as a physiological tool. No nutrition, no life coaching — a precise scope, a scientific rigour.

Programming

Periodisation of effort

Strength, conditioning and mobility cycles calibrated to your professional load. A focus on long-term progression and adherence, not on immediate intensity.

Physiology & Biomechanics

Functional assessment

Objective measurements: maximal strength, aerobic capacities (VO₂, thresholds), grip test, body composition. A scientific foundation for optimising physical capacity in service of cognitive performance.

Monitoring

Longitudinal analysis

Tracking internal load (HRV, RHR) via connected devices (Polar H10, Oura, Whoop, Garmin). Weekly adjustments based on your recovery signals.

Measurable effects

RHR · Resting HR
Decrease in resting heart rate
HRV · Variability
Stabilisation of heart rate variability
Strength
Progression on fundamental movements
Aerobic capacity
Elevation of thresholds and VO₂ max
Perceived energy
Greater stability across the working day
Functional autonomy
More freedom in everyday movement
The Path

Three steps toward autonomy

Initial — 90 minutes
The physiological assessment

Review of medical background, biomarkers and recovery signals. Field testing to evaluate strength, aerobic capacity and HRV profile.

Construction — 7 days
Designing the protocol

A tailored training framework, periodised to your work cycles, designed to integrate into a saturated schedule.

Support — Continuous
Dynamic adjustment

Weekly review of metrics. Intensity evolves according to your recovery signals and professional load.

Data & Reality

Adaptations that are quantifiable

Every programme is documented. Below, the trends observed across 21 long-term clients with full physiological tracking.

Functional training, goblet squat
Change from within, objectively.
+100 to 200%

Strength

Average progression on fundamental movements over 12 to 24 months.

2 to 5 bpm

RHR

Average decrease in resting heart rate over 12 months.

85%

Adherence

Average long-term retention rate of the protocol.

Profile case studies

Senior official, education sector Body fat halved

Elite analytical profile, 5h/week, strict periodisation. The analytical mindset deploys fully within a structured, measurable framework.

Executive, technology sector −14 kg held over 14 months

High-intensity environment. A progressive overload over 14 months produced durable adaptations.

Teacher, scientific preparatory classes Strength tripled

Constant intellectual pressure, 2h/week. Training delivered a major increase in functional strength (+200% on bench press and horizontal pull).

Founder, technical industry Athletic restoration

Travel and saturated schedule. One hour of structured effort per week was enough for a major body recomposition and a clear gain in perceived energy.

Enterprise

In service of your teams

When a team's performance depends on its collective lucidity, investing in the system that supports it becomes strategic. I work with high-stakes organisations — consulting firms, technical leadership, research teams.

Discovery format

Introduction workshop

A half-day to lay the groundwork: physiology of recovery, cognitive load, concrete levers. Ideal for orienting a team or executive committee.

Programme format

6-week programme

Structured group accompaniment: weekly sessions, individualised tracking via wearables, group monitoring. From small teams to extended groups — I have technically supervised sessions of 60+ participants.

Leadership format

Executive coaching

A bespoke protocol for a leader or key contributor. Identical to my individual coaching, in a confidential framework negotiated with the company.

About

The human behind the method

In 2017, between preparatory classes and financial audit at KPMG, my own system gave way. The burnout delayed my graduation. It was also a turning point.

I learnt the hard way that good decisions are not made within an exhausted body. Performance does not lie in the accumulation of hours, but in the physiological infrastructure that carries us.

Over 7+ years I have worked with 70+ individual clients — university professors at top engineering schools, executives, researchers, high-level amateur athletes — and led collective programmes: Volleyball at Nationale 3 level, functional sessions of up to 30 people, and technical supervision for groups of 60+ participants.

Today I hold two complementary roles: Strength & Conditioning Coach on the field, and Human Performance Strategist in the design of hybrid strategies — health, physical, cognitive.

2014 – 2017
The corporate system

Master's in Corporate Finance from a top French business school (Rennes School of Business). Audit roles at French Red Cross and KPMG France. First burnout in late 2017.

October 2018 — present
Strength & Conditioning Coach

Independent coach. Over 7 years of individual and collective coaching: 70+ individual clients, group leadership of up to 30 people, Volleyball coaching at Nationale 3 level.

2019 – 2021
Scientific grounding

State-certified diplomas BPJEPS and DEJEPS Sport Coaching at the CREPS of Châtenay-Malabry.

December 2025 — present
Human Performance Strategist

Designing hybrid performance strategies (Health · Physical · Cognitive) for executives, senior managers and high-cognitive-load professionals. Biomechanical and physiological coaching.

2025 – 2026
Cutting-edge research

Bachelor's in Sport Science, Sport Coaching specialisation (Université d'Évry Paris-Saclay), to integrate the latest physiological advances into protocols.
