7) Seated leg tucks

Exercise designed to work the whole length of the abdominals.
The subject sits across a horizontal bench. With the torso closing a 45 degree angle with the surface of the bench and the legs stretched out, knees slightly bent he/she starts raising the ribcage and the legs simultaneously until the movement is complete. All of the motion is done while curling the back as if rolling into a ball. At the top of the motion the contraction is held on for a second then torso and legs are lowered back into the starting position.
