The introduction to the modern research included, as there is a large group of different situations and movements for stretching and callanetics exercises, all of which aim to achieve what the body needs in building and developing its kinetic abilities under scientific or educational controls to achieve the purpose for which those exercises were developed, and the research problem emerged through the low level of physical activities Especially the muscle lengthening exercises, which leads to continuous muscle spasms, and the researcher used the experimental method for one sample, they used motor abilities tests for this purpose. By applying the updated callanetics and lengthening exercises to a random sample of the research community, the research sample consisted of (7) trainees. The results were treated by statistical means (SPSS statistical bag) and the results were presented in tables and points and discussed. The study concluded that the adoption of the updated stretching and callanetics exercises develops some of the kinetic abilities of swimming practices at the age of (35-40). The researcher recommended the necessity of adopting the updated callanetics and lengthening exercises for swimming practices aged (35-40).
