1. An exercise support system comprising: a plurality of imaging devices configured to capture videos for movements of a person to be evaluated; a 3D generation section configured to generate 3D model data of the person to be evaluated based on the video captured by each of the imaging devices; an evaluation reference memory configured to store reference 3D model data that is 3D model data to become an evaluation reference of an exercise; and an evaluation section configured to evaluate the movements of the person to be evaluated by comparing between the reference 3D model data and the 3D model data generated by the 3D generation section in each body part of the person to be evaluated.
