Fitness instructors often recommend doing different types of sit-ups to tone the abdominal muscles, although some exercises may be more strenuous on the lower spine. Two common types of sit-ups are the leg-raised sit-up and the crunch. In the first case, you start by lying fully flat on your back, legs straight and arms by your side. Then, you slowly raise your legs just slightly off the ground. In the second case (the crunch), you start from the same initial position, but instead of raising your legs you raise your shoulders and head off the ground, slowly and just slightly.
