Second 25: Lie on back with left foot on floor and right ankle on left knee. Keep right elbow on floor and raise left elbow toward right knee. I.e., you are twisting as you raise one elbow toward the opposite knee. This works your obliques.
Third 25: Reverse feet and elbows.
Fourth 25: Cross your ankles and lift your legs up into the air. Legs don't have to be straight up, but keep feet above knees. While holding legs up, use abdominals to raise head and shoulders.
