The Science of Sustained
Human Performance.
Deep-Health operates at the intersection of physiology, psychology, and performance — helping leaders, athletes, and organisations build measurable, sustainable human capability.
Led by Sanjay Dev — Performance & Wellness Consultant with 20+ years of interdisciplinary experience across human science, behaviour, and organisational performance.
A Systems Approach to Human Performance
Most health and wellness solutions fail because they isolate variables — fitness, nutrition, or mindset. Deep-Health does the opposite.
We operate on a systems-based model, where performance is a function of interconnected biological, psychological, and behavioural inputs — not any one of them in isolation.
What happens in one hour of coaching is insignificant compared to how the remaining 23 hours are lived.
Physiological Health
Metabolism, recovery, inflammation, and internal health — the biological foundation that everything else rests on.
Cognitive & Psychological Resilience
How the mind handles sustained pressure, cognitive load, and emotional demand — and how to build lasting capacity in these areas.
Behavioural Consistency
The systems and environmental design that make performance-supporting behaviours automatic — not dependent on motivation or willpower.
Organisational & Lifestyle Demands
The external pressures — work structure, culture, travel, stress — that interventions must be designed around, not in spite of.
Sanjay Dev
Founder & Lead Consultant, Deep-Health
Built on Science.
Shaped by Two Decades
of Real-World Application.
Over the last two decades, Sanjay Dev has worked across the full spectrum of human performance — from elite athletes to high-stakes executives and founders. His career did not begin in fitness. It began in science.
With a foundation in applied sciences and early exposure to structured problem-solving through wealth management and business, Sanjay developed a systems-oriented lens early in his career.
As a former athlete, he transitioned into strength & conditioning — earning his CSCS certification and working with top-seeded athletes. But over time, a deeper pattern emerged. Performance was never just physical.
- Chronic stress and burnout patterns in executive clients
- Sleep disorders — including sleep apnea — affecting output quality
- Metabolic dysfunction presenting as fatigue and cognitive decline
- Decision-making degradation under sustained cognitive load
Performance is not built in sessions.
It is built in systems.
Today, Sanjay works with leaders, athletes, and organisations to translate complex human science into measurable performance outcomes — across physiology, psychology, and behaviour.

The difference is not just methodology. It is the underlying belief about what health is for — and what it can produce when it is genuinely treated as a performance input.
Interdisciplinary by Design
Physiology, psychology, and nutritional biochemistry integrated into every engagement — not treated as separate modules.
Applied Across Contexts
From individual leaders to entire workforces — the same rigour and depth, scaled and adapted to the context.
Measured, Not Perceived
Every engagement is designed for outcomes that can be tracked, validated, and built upon — not felt temporarily and then forgotten.
Trusted by Leaders
& High Performers.
From former international cricketers to managing directors of global brands — the people who have worked with Sanjay speak to the same thing: depth, personalisation, and results.
Sanjay’s approach to fitness and training and his knowledge is on par with any international coach — and it certainly helped me with my fitness goals. I wish him the very best in all his endeavours.
Sanjay is a highly disciplined Coach who cares about his clients. He observes everything in terms of food, rest, psychology and adapts his programs to his clients.
I really enjoyed training with Sanjay. He’s knowledgeable and charted out a holistic plan that worked very well for me. The fact that he’s super friendly was an added plus point. Would definitely recommend Sanjay for one’s training requirements.
Sanjay is truly an excellent coach & a knowledgeable holistic professional. Skilled, thoughtful and a pleasure to work with.
