|Oblique Sit Up|
Core strength is fundamental to pilates philosophy and the oblique sit up is a very important way of strengthening the underlying abdominal muscles that can be forgotten when doing standard crunches or exercises simply focusing on a "six pack".
While the focus of the oblique site up is not on the common six pack muscle groups it is essential for good abdominals to exercise the oblique muscles as they are what gives the flat stomach.
The main purpose off this exercise is however, core strength.
Do not apply any pressure with the arms.
If the neck hurts stop immediately.
