An exercise wand and method are set forth which are particularly adapted to exercise the lower torso through twisting or bending. The wand includes a hollow tube having a closure at each end. The tube contains a plurality of movable spheres which extend 93% to 97% the length of the tube between the closures. Twisting or bending in a first direction shifts the spheres to abruptly engage and stack against a rigid closure at one end of the tube, the shifting spheres altering the center of mass for the wand and imparting momentum to the wand to urge full twisting or bending. Reverse twisting or bending shifts the spheres to abruptly engage a rigid closure at the other end of the tube, altering the center of mass and imparting momentum to the wand to urge full twisting or bending.
