The Oblique Crunch (also known as the Twisting Crunch and Twisted Crunch) is a slight variation of the Ab Crunch.
The main difference in performing this exercise is that you "twist" your body when you do it so that your left elbow heads towards your right knee (and vice versa).
The main difference regarding the muscle groups involved is that, where the Ab Crunch concentrates on your Rectus Abdominus (i.e. the front part of your abs), the Oblique Crunch concentrates more on your obliques - the muscles to the side of your abs.
