In a hyper-aged society, health promotion for middle-aged and older people—especially women—became a serious social issue. Health promotion is highly important from the viewpoint of reducing healthcare cost and improving QOL. Among a variety of health promotion approaches, we especially focused on health promotion by exercises. Resistance training is regarded as one of the effective health promotive exercises. However, resistance training will not effectively work if the training is done with wrong postures and speed. In this paper, we propose a VR system that supports to perform correct exercises without relying on training instructor. Specifically, we developed a visualization system that superimposes the postures of the training instructor and trainee in a 3D virtual environment and helps the trainee to learn resistant training in the right manner.
