Cable Woodchop

The cable woodchop is an excellent rotational exercise for the oblique muscles in the abs. Start by holding the handle over the shoulder with outside arm first, then cupped with hand closest to the pulley. Next, pull handle across your body keeping the outside arm straight and elbow high on inside arm. As the weight moves across your body you should feel a contraction move from upper (external) oblique to the opposite side lower (internal) oblique.
