The obliques crunch is a great ab exercise that targets the rectus abdominis, the external obliques and internal obliques.

How to do it:

* Lie on your back with your knees bent and feet flat on the floor.
* Slowly drop your legs to the left and let your knees rest near the floor.
* Place your fingertips to the side of your head just behind your ears.
* Push your lower back into the floor flattening the arch and hold.
* Curl up slowly so both your shoulders lift off the floor a few inches.
* Hold for a count of 2 and return to the start position.
* Repeat for the desired number of reps and switch to the other side.
