An interacting exercise device comprising: at least one driving device having at least one driving wheel and at least one driven wheel set; and at least one non-concentric actuator; wherein the interacting exercise device includes a mounting space, in which the driving device and the non-concentric actuator are mounted; wherein the interacting exercise device further comprises at least two shafts, consisting of at least one shaft respectively connected to the at least one driving wheel and at least one shaft respectively connected to the at least one driven wheel set; each of the shafts being at least partially inserted into the mounting space by means of a bearing; wherein each of the shafts connected to a corresponding driving wheel has a first end and a second end, the first end being respectively inserted into the mounting space through the bearing and being passed through the corresponding driving wheel; whereas the second end thereof respectively protrudes from the mounting space and is connected to a corresponding operation portion; the shaft associated with the driven wheel set being inserted into the mounting space by means of a bearing and passed through the driven wheel set; the driven wheel set includes a large wheel and a small wheel coaxially disposed on one side of the large wheel; the non-concentric actuator includes a disc and a tiny wheel coaxially arranged at one side of the disc; a counter weight is mounted around at least one end of the disc; a diameter of the driving wheel is larger than a diameter of the small wheel of the driven wheel set while a diameter of the large wheel of the driven wheel set is larger than a diameter of the tiny wheel of the non-concentric actuator; wherein the driving wheel is associated with the driven wheel set while the driven wheel set is associated with the non-concentric actuator, wherein the driving wheel drives the small wheel of the corresponding driven wheel set while the large wheel of the driven wheel set drives the tiny wheel of the corresponding non-concentric actuator; when the operation portion operated drives the driving wheel to rotate, the driven wheel set is rotated fast at the same time and the non-concentric actuator is further driven to rotate quickly by the driven wheel set; then the non-concentric actuator shakes and vibrates owing to unbalanced centrifugal force and vibration generated is delivered to the interacting exercise device; thus the interacting exercise device shakes and users' bodies are shaken passively so as to achieve passive motion and active motion. at least one driving device having at least one driving wheel and at least one driven wheel set;
