Widowed women often experience psychological pressures, and their psychological security can be influenced by various factors such as employment, housing situations, and age.

Methodology: The study utilized an experimental approach, involving a sample of 30 widowed women who were affiliated with the Benaa Association for the Care of Widows and Divorced Women in the Eastern Province of the Kingdom of Saudi Arabia. The participants were divided equally into two groups: an experimental group and a control group. The experimental group underwent the cardio-karate training program, while the control group did not receive any specific intervention.
