Sit on the sit-up bench and place your feet beneath the roller pads. Place your hands behind your head or atop your chest.
1. Inhale and incline your torso less than 20 degrees. Generally, this angle is reached when you have raised your torso until the bottom of your shoulder blades are barely touching the bench.
2. Move your torso back up, Slightly curling your torso to place more stress on the rectus abdominis.
3. Exhale while you complete the movement. Return to the starting position for the next repetition.
Notes: This exercise works the entire rectus abdominis muscle wall and the iliopsoas, tensor fasciae latae, and rectus femoris in the quadriceps group. The latter three muscles help tilt the pelvis forward.
