Authors and collaborators have continued clinical practice and research on rehabilitation and self-training, in which various problems were found.
Protocol: The author himself tried home self-training exercise of push-up for 2 months, which was successfully achieved.
Results: Positive changes were 94 to 96.5cm in chest circumference, and 45 to 100 times in continuous push-up, respectively.
Discussion: From the viewpoint of sport psychology, close relationship among motivation, self-efficacy and performance has been observed. Self-efficacy can influence one’s beliefs concerning accomplishing and continuing the task, activities and effort. This report will hopefully become the reference for future practice and research development
