# 5 Abs Exercise – Jackknife
The Jackknife is also related to the simple crunch; however, this time, the body jackknifes into position. In the crunch, the lower body is steady while the upper body moves. With the jackknife, it is the whole body moves into position. This exercise works on all the abdominal muscles as well as leg and arm muscles.
At the starting position, the whole body is stretched out on the floor, with the arms fully extended above the head. Then, the arms and legs are lifted simultaneously so that, ideally, the fingertips will reach the toes. The abdominal muscles are contracted to initiate the movement; then, these are relaxed to allow the body to return to the starting position.
#4 Abs Exercise – Reverse crunch
Just as its name suggests, the reverse crunch is the opposite of the usual crunch. This is especially good on the lower abs. It ranks better than the usual crunches because of the added challenge of lifting one’s body against gravity using the abs muscles only.
It is done by, first, lying on the floor with the arms relaxed at the sides, on the floor. Then, with the feet crossed, the knees are brought to the chest until it is bent at 90 degrees. Then, using only the ab muscles, the hips are lifted off the floor while the legs reach for the ceiling. Slowly, the body is lowered down.
