Our range is designed for sports activities at school or a children's gym.According to recommendations by the World Health Organisation (WHO), children should do at least one hour of physical activity a day.The critical role of sport and its benefits for children's development and physical and mental well-being are proven: development of motor skills and agility, self-confidence, and belonging to a group

What do we mean by educational gym and sports activities?

PE lessons and sports activities allow children to unleash their energy and explore all the physical possibilities available to them: jumping, balancing, stringing together a series of movements, and doing tricks. Although this kind of exercise is mainly done in PE lessons, it can also be done in clubs outside of school.

Sport offers numerous benefits for both kids and teens, from moving around to having fun and interacting with friends, all while learning how to get along with others!
