Abstract

An exercise analysis device includes: a first specifying unit that specifies an inclination of a first axis which lies in a major axis direction of a shaft of an exercise tool at a time of address or a time of impact in a swing, using output of an inertial sensor; an acquisition unit that acquires a first criterion axis to be compared to the first axis; and a comparison unit that compares an inclination of the first axis to an inclination of the first criterion axis.
