• and
• two arm-exercising assemblies located at left and right sides of the chassis respectively, each of the two arm-exercising assemblies having a handlebar and a joint bar, each of the handlebars having a lower portion and an upper portion, the lower portions being pivotably attached to the second linking-up parts, the upper portions being for a user to hold to take exercise based on a closed elliptical trajectory, each of the joint bars having a rear end portion and a front end portion, each of the rear end portions being pivotably attached between the upper and lower portions of each handlebar, the front end portions being pivotably attached to the chassis.
