Equipment
cable
Set a cable at chest height and stand side on, holding the handle with both hands at your chest. Step away until there is tension, and set your feet shoulder width. Press the handle straight out in front of you and resist the cable's pull to rotate you. Hold briefly, then return to your chest. This is an anti-rotation exercise. The work is in not moving. Common mistakes: letting the torso rotate towards the machine, and using so much weight that resisting is impossible.
