The hanging crunch an abdominal exercise that targets the rectus abdominis or "six-pack" muscles. It can be performed hanging from a bar, on a dip station or parallel bars, or if grip strength is a limitation, by placing the elbows in ab straps. If hanging from a straight bar is uncomfortable to the wrists or shoulders, you can also perform them hanging with a neutral grip (palms facing one another). It is similar to a hanging knee raise, but with more spinal curling and a more pronounced "crunch" at the top.
