Decide on a number of reps and hit your goal. Its OK to take a break.

Suggest 10 to 20 reps.

1. Single Arm Cable Pushdown begins in a tall standing position, with feet about hip-width apart, core braced, the crown of the head tall, standing in front of a cable machine, with one hand gripping a cable handle, elbow bent, hand starting right in front of the shoulder, hand pronated (palm facing away from the body).
2. To initiate the movement, extend at the elbow and push the arm down so the arm is completely straight at the bottom of the move.
3. Then, with control, slowly bring the knuckles back up to the front of the shoulder.
