A treadmill has a housing covering from above a base, a front supporting rod of the base has a central supporting column connecting a left and a right linkage in a symmetrical way; each linkage has a peddle, its front end connects a linking member, the two linkages are connected at angular positions but being connected pivotally to the two lateral sides of the supporting column; each peddle is connected on its rear end with a buffer which is connected to the front supporting rod to brace up the peddle, and to form impedance force; a left and aright ski stick each is fixedly connected with a peddle, a supporting rack is connected with the supporting column and is mounted thereon a wheel to limit moving of a flexible member of which two ends are respectively connected with the left and the right linking members, in order that the peddles can move up and down in inclined positions. A user can thus allow two hands to control the actions of pushing and pressing with the ski sticks to do treading exercise in a crossed way and in an inclining mode as if the user is skiing; the object of doing plastic art on a waist, a hip and a thigh etc. can thus be attained.
