Lie flat on your back. Raise your arms to 90 degrees in front of you, so your hands are pointing towards the ceiling. Bend your knees and hips to 90 degrees. Engage your deep abdominal muscles and maintain a neutral spine. In a controlled movement, lower one arm to the floor above your head, while you lower the opposite leg to the floor in a straight position. Do not let your lower back arch too much, try to flatten your spine gently towards the floor. Return to the start position. Repeat to the opposite side. This exercise is a core strengthening and co-ordination exercise.

This exercise really helps with core stability. I've been incorporating it into my routine and can feel the difference.
