An adjustable length pole resiliently tethered at the waist to a body harness is used in exercises to condition certain selected muscles. The body harness is preferably of a type known in mountain climbing, having a belt and two straps encircling the crotch. Two elastic tubes, one on each side of a user's body, are each connected at one end to the body harness and at the other end to the pole near the ends of the pole. These tubes resiliently resist bodily movement. The effort of overcoming this resistance provides muscle conditioning. The pole terminates in enlarged, flat portions large enough to overlap the user's hands, with the palm held against the flat portions, fingers spread out. With the pole held by contact with the palms, arms outstretched laterally from the body, with the center of the pole resting on the back of the user's neck, the user twists about the spinal column to exercise the external oblique abdominal muscles. Alternatively, arm extension exercises may be performed in which the user raises and lowers the arms to further develop the oblique abdominal muscles. Lifting exercises, such as the military press, may also be used to improve arm and shoulder muscles.
