1. An exercise support system comprising: a plurality of imaging devices configured to capture videos for movements of a person to be evaluated; a microcomputer configured to generate 3D model data of the person to be evaluated based on the video captured by each of the imaging devices; and an evaluation reference memory configured to store reference 3D model data that is 3D model data to become an evaluation reference of an exercise, the microcomputer being further configured to perform an evaluation of the movements of the person to be evaluated by comparing between the reference 3D model data and the 3D model data that is generated, in each body part of the person to be evaluated, acquire information related to the each body part of the person to be evaluated in each part based on the 3D model data that is generated, and approximate a reference body shape to a body shape of the person to be evaluated based on the information and correct the reference 3D model data to data based on the reference body shape, the microcomputer being further configured to perform the evaluation of the movements of the person to be evaluated by comparing between the reference 3D model data corrected based on the reference body shape and the 3D model data that is generated, in the each body part of the person to be evaluated.
