How to Do a Straight Leg Sit Up

The straight leg sit up is a terrific way to strengthen the abdominal muscles while increasing flexibility. In order to avoid injury to the lower back, it's crucial to practice developing the proper technique. Concentrate on having the abs do the work, rather than the muscles in the hips or thighs.

Instructions

Difficulty: Moderate

1. Wear comfortable clothing that allows ease of movement. Place an exercise mat or large folded towel on the floor to provide a padded surface.
2. Stretch out with the legs extended straight from the body. Point the toes to the ceiling. Press the small of the back flat against the mat.
3. Pull the toes towards the shins to provide more strength for the sit-up. Extend the arms along the sides with the fingers pointed towards the toes.
4. Curl the neck and head up and forward. Use the abdominal muscles and roll up into a sitting position in one smooth motion while reaching for the toes. Resist the temptation to use the arms to help or to propel the upper body forward
5. Reach past the feet with the finger tips to complete the upward motion. Slowly lower the upper body to the mat using the abdominals to control the motion. Press the small of the back flat into the mat.
6. Repeat the sit-up in sets of 3 to 5. Do three sets in any workout. Be sure to cool down sufficiently with a series of stretching exercises following any workout.
