Begin lying on the floor with straightened legs and arms outstretched overhead. In a fluid and controlled motion, bring your legs up to meet your hands above your belly button. Shoulders should raise just until they no longer touch the floor. Lower slowly. Keep your legs as straight as possible, and core tight throughout.

If you feel weakness in your lower back or neck, take a few moments in the lying position to recover then continue the set.
