About
César Grelié
Multi-disciplinary athlete, certified sports and wellness coach, founder of Vitaleo Domicile. Born into a family of athletes and health professionals, I turned other people's wellbeing into my profession — with a holistic approach uniting mobility, strength training and nutrition.
My journey
I was born into a family of athletes and health professionals: my mother is a midwife and osteopath, my father a windsurfing instructor, my sister a sports coach and Thai massage practitioner. A former gymnast, I have always cared about people's wellbeing — it felt natural to make it my career.
A former gymnast, CREPS-qualified sports educator specialized in mobility and Nordic walking, I keep training every year with recognized specialists.

My philosophy
To become a hybrid athlete, as versatile as possible: able to adapt to any sport, with a functional body that optimizes longevity. The playful side of sport is essential to me.
My goal: to spark real, lasting change together, by getting to know your body better and freeing it from limiting tensions.
My approach
Three pillars, one holistic approach
Mobility
Moving freely through wide ranges of motion, combining strength and suppleness — to feel comfortable in your body for as long as possible and reduce the risk of injury.
Strength training
Training anywhere using your bodyweight, developing complete athletic qualities: strength, flexibility, endurance and explosiveness — for too long wrongly kept apart.
Nutrition
Healthy, enjoyable eating that respects the body's physiological needs, adaptable whether you travel or eat out — with no deprivation and no guilt.
