PURPOSE: An exercising machine for strengthening waist is provided to strengthen leg muscular and the waist and to supply elastic force to a rotary upper plate in up and down motion and twist motion, and to prevent the dispersion of the center of gravity. CONSTITUTION: An exercising machine for strengthening waist comprises: a fixing lower plate(100) which includes a plurality of non-slip stages and in which a cylinder is installed on the upper center of the fixing lower plate; a rotary upper plate(200) which is slid in the cylinder and is installed on the upper side of the fixing lower plate to buffer a load in contacting with the ground; a compressive elastic member(300) which is located on the cylinder upper part of the fixing lower plate and the outer circumference of the load of the rotary upper plate; and a tension elastic member(400) which is transformed when the rotary upper plate is twisted.
