Abstract
An elliptical exercise apparatus includes a base, an upstanding frame extending upwardly from the base, a crank assembly including left and right crank members connected respectively and rotatably to left and right sides of the upstanding frame, and a link rod assembly including left and right first link rods each having first to third connection points. The first connection point is connected rotatably to the corresponding crank member. The link rod assembly further includes left and right second link rods each having rear and front ends connected pivotally and respectively to the upstanding frame and the corresponding second connection point. A pedal assembly includes left and right pedal rods each having a front connecting section connected rotatably to the corresponding third connection point. The pedal rods are mounted on the base to move in a substantially front-to-rear direction relative to the base.
