Lie on your back holding a Swiss ball between your feet. Keep your legs straight and lift the ball off the floor. Make sure your lower back stays on the floor and then rotate your hips to the right as far as is comfortable. Then rotate your hips to the left to finish the rep. Repeat ten times, then move on to 1B with no rest.

Hold a light dumb-bell in each hand and stand with your feet shoulder-width apart and your knees slightly bent. Hold both dumb-bells by your chin, and then punch out with your right arm as if in slow motion. As you bring your right arm back, punch out with your left and so on. Your abs should be contracted throughout the exercise.
