Lie down on the floor with your knees bent and arms to the side of your torso with the palms on the floor, or behind your head (remember to cradle the head/neck to avoid pulling it forward). Now focusing on lifting from your lowered abdominal muscles, slowly lift your lower body up off the floor. Hover for a brief moment, and then back down. You may focus on moving only your lower abs during this exercise, or you may also choose to bring your upper torso toward your knees. Always be cognizant of your neck to avoid pulling it. The movement (and the reward) comes from contracting your abdominal muscles.
