Abstract
An exerciser includes a seat attached to a supporting frame unit, and a swing rod disposed pivotally on the supporting frame unit and adapted to be swung by a portion of a human body so as to rotate synchronously with the portion of the human body about a rotating axis. A light emitting element is mounted on an assembly of the supporting frame unit and the swing rod so as to generate a light beam that extends along the rotating axis. When the human body sits on the seat, the portion of the human body can move on the supporting frame unit so as to align the light beam accurately with the rotating axis of one joint of the human body, about which the portion of the human body rotates.
