Two ends of the two connecting parts 40 are respectively pivotally mounted on the bottom ends of the two handlebars 28 of the reciprocating mechanism 26 and two sides of the wheels 34 of the circular movement mechanism 32 . Under the combined action of the reciprocating mechanism 26 and the circular mechanism 32, the connecting member 40 can generate an elliptical moving track, as disclosed in US Pat. No. 5,242,343.

Two parallelogram mechanisms 42 respectively have a first connecting rod 44, a second connecting rod 46, a third connecting rod 48 and a fourth connecting rod 50, wherein the first and third connecting rods 44, 48 are parallel to each other, and the second connecting rod 44 is parallel to each other. The second and fourth connecting rods 46, 50 are parallel to each other. Two ends of the second and fourth connecting rods 46, 50 are respectively pivotally connected to the first and third connecting rods 44, 48, so that the four connecting rods form a four-linkage mechanism. A pedal 52 is disposed on the top of the first connecting rod 44 , and the first connecting rod 44 is pivotally mounted on the connecting member 40 . The bottom end of the third connecting rod 48 is connected with a guide rod 54 , and the guide rod 54 passes through the guide groove 24 of the four rollers 22 , so that the planar mechanism 42 can move back and forth horizontally relative to the bracket 10 .
