Postural problems, in the form of bad and irregular posture or structural deformities, are occurring more and more frequently in children and young people and have a negative impact on the general quality of life and body functionality. Numerous factors such as less physical activity and long-term retention of an incorrect body position affect their appearance. Scoliosis, kyphosis and lordosis are the most common postural deformities, and they differ depending on the area of the plane in which the deviation of the spine is manifested. Bad and incorrect posture, especially when it is not noticed and prevented, often results in development of deformities. Doing any form of physical activity is extremly important in childhood for proper growth and development. Physical activity and intensity must be adapted to the individual characteristics and current status of the child. The aim of the paper is to present a model of kinesitherapy exercise, the application of which would prevent development of postural deformities. Presented exercises are conceptually designed for use in school or home conditions, which makes them practical and easier to access. Applying the exercise models presented in the paper, and their proper structuring, has a positive effect on increasing daily activity and strenghtening the target muscles responsible for maintaining good body posture.
