Summarize the following:
This exercise can only be done if you or your gym has a weight machine tower with attachable cables. You will need a standard handle (often made of plastic, rope, metal, or rubber). Attach the handle to the cable's metal ring. Move the cable to the highest rung of the pulley system. The wood chop can also be performed with an exercise ball. Stand next to the cable (rather than facing it). Grab the cable with the closest hand. Step away from the tower, about an arm's length, while holding the cable. Make sure there is tension in the cable and your arm is straight. Your arm and the cable should be on the same angle. That is, your arm should not be bent downwards from the cable. Place your feet shoulder-width apart. With your other hand, reach up to the handle. Both hands should be grasping the handle now. Grasping the handle, twist your upper body and move the handle diagonally downwards across your torso. Aim for your outer knee. During this time, your inner foot (closest to the tower) should pivot and you should keep your knees bent. Keeping your arms straight, return the handle to its original position. Do not bend your back. Perform three full sets. Then reverse your body's position. Repeat the moves on the other side of your body. During the exercise, focus on keeping your abs tight. This exercise is quite complicated. If you have access to a trainer, please ask for instruction before completing this move.

Summary:
Set up the equipment. Find your position. Complete the move. Complete ten repetitions.
