The purpose of this study clarifies ways of handling new extracurricular sport activities aiming to lead to life-long exercise. This study focused on junior high school students who joined an extracurricular sport activity club for the first time. We established one special club (one aiming for gaining physical strength) where they could choose exercises that would be suited to their individual physical ability. We studied and analyzed how it effects students’ interests and motivation about exercise, or the improvement of their physical strength after attending the extracurricular sport activities, utilizing the results of their fitness tests and surveys. As a result, in regards to students doing aerobic exercise, regular activities continuously done would improve their basic physical strength. In addition, their awareness (their likes or dislikes, what they were good at or bad at, or their motivation at doing various activities) to their overall well being seemed to be maintained even though the average scores for fitness activities decreased with age. As a conclusion of this study, we must state that doing “The Physical Strength Improvement Club”, which could accommodate students’ needs and the improvement of their physical strength and their life styles through attending this club, would increase the students’ core physical strength and broaden their own awareness about their physical well being.
