A miniaturized track exercising device includes a chassis on which a counterweight wheel set is provided. The counterweight wheel set is provided with a resistance adjusting unit. Two crank arms extend in opposite directions and are arranged on opposite sides of the counterweight wheel set. Each crank arm is pivotally connected to a pedal in an offset manner. The pedals are provided with a guide rail unit that is opposite to the crank arms with respect to the pedals and that provides a pivot joint and a fulcrum. Thus, when the pedals are being treaded, with the counterweight wheel set inducing a sufficient resistance that is adjusted with the resistance adjusting unit and the guide rail unit providing support against gravitational force acting on the pedals while the pedals undergo track motion, the pedals are constrained by the guide rail unit to generate an elliptical track motion.
