A fitness apparatus includes a chassis, two linkages, two handlebars, two cranks and two joint bars. Each of the linkage includes a first linking-up part and second linking-up part transversally. The first linking-up parts are pivotably attached to the cranks for revolution of the cranks relatively to the chassis. Each of the handlebars includes a lower portion pivotably attached to the second linking-up portion, and an upper portion which can be held by the user to move along a closed elliptical trajectory. Each of the joint bars includes a rear and portion pivotably attached between the upper portions and the lower portions, and a front end portion pivotably attached to the chassis. In this way, the user's arms can take exercise effectively along an elliptical trajectory to further prevent the user from suffering sports injury resulting from incorrect posture.
