The crunch with knees to the chest, better known as double crunch, is an advanced level exercise for training the abdominal area and for the stabilization of the lumbar area. The "reverse crunch" part of this exercise, the one that involves the legs, trains in particular the lower part of your abdominals. It is important to remember that one of the muscles involved in this exercise are the hip flexors: they are the first to be activated during the movement of the knees toward your chest.
