Rida Ouerghi was born in Aubagne in the Bouches-du-Rhône region of France. His career has allowed him to experiment and study several physical and sports activities (team sports, racket sports, combat sports, swimming, athletics, pilates, dance, yoga ...). He is especially fascinated by the development of motor skills and physical qualities from infancy to adulthood. He is also interested in the management of fitness from adulthood to old age and its impact on physical, mental and social health and well-being. For him, the body is a complex whole which cannot be studied other than through a systemic and multidisciplinary approach from a practical and theoretical point of view. He studied at the Faculty of Sports Sciences in Marseille to become a physical trainer and teacher of physical education and sports. He was a high-level athlete in karate, medalist at the individual French and European championships with his club Stade Marseillais Université Club (SMUC). His experience in teaching and training has led him to work with kindergarten classes, primary schools, colleges, high schools and in sports halls. He currently lives in Paris and teaches physical and sports education at Sorbonne Nouvelle University. He is the author of several books at Gallimard Jeunesse, the objective of which is to promote and encourage children's motor skills. His works are translated into several languages.
