Cable Woodchop

Set the cable at one height and stand side-on to the stack, feet shoulder-width, weight even between both feet. Grip the handle with both hands and pull it across your body in a diagonal line, rotating through your torso and hips rather than just your arms. Keep your arms relatively fixed relative to your chest so the rotation comes from your core and hips turning as one unit, not your shoulders yanking the handle across. Control the return back to the start at the same speed you pulled it, resisting the cable's pull rather than letting it snap you back. Switch sides to work the other diagonal.
