The move: Contract your abdominal muscles. Raise both dumbbells out to your sides in a semicircular motion. Pause for a second before gradually lowering the dumbbells to the starting position. Control your movements throughout the entire exercise, exhaling as you raise the dumbbells and inhaling as you return to the starting position. Continue until the entire set of 8 to 10 repetitions is complete. If you are performing multiple sets of this exercise, take a deep breath, wait 15 to 30 seconds, and begin your next set.
Tip: Keep your back straight and your head up as you go through the move.
