An exercising device includes a hand operated member pivoted to a frame and connected to a first coupler, a lever member pivoted to the frame and connected to the hand operated member by a linking bar, and a second coupler member with a front coupling end connected to the lever member and a rear coupling end in friction contact with a motion guiding member which is journalled on first and second crank members. As such, the second coupling member proceeds with a reciprocating movement in a substantially elliptical path which is restrained by the pivot connection between the handle operated member and the lever member.
