Great care and excellent technique are required to strengthen the abdominal muscles with sit-ups.

To be effective, sit-ups must pull the torso upward from a lying position toward the knees using only the abdominal group.

Often, however, other, more powerful, muscles (those that flex the legs and hips) do much of the work.

This is especially true with straight-leg sit-ups. Bending the knees during sit-ups helps neutralize the action of the hip flexors and makes the abdominal muscles work more.

Even so, the abdominal group tends to be involved only in the initial phase of the sit-up, after which the hip flexors take over.

Conducting sit-ups with momentum, knees bent or not, does not work the abdominal group.

That is why raising slowly only part way works the abdominal muscles best.

Sit-ups also can be hazardous to your lower back, especially when using the straight-leg variety, which arches the back and may create overextension and strain.

Twisting (right elbow to left knee and vice versa) at the top of the sit-up movement is not only useless, it places tremendous rotational stress on the lower back that can lead to injury.

Do not interlace the fingers of your hands behind your head as this will place a strain on the neck - place your hands on either side of the head.

When doing sit-ups, never push through back pain. Stop immediately at even the slightest twinge in the lower back.
