This stretching exercise of an overhead side bend will help maintain spine flexibility. Besides the abdominal muscles, the exercise also targets the lower back, sides, triceps and shoulders.
1. Stand with feet shoulder-width apart and hold the dumbbell above your head, squeezing your ears with your upper arms to engage your core.
2. Now, pull your abs to your spine and lengthen your spine as you bend slowly to the right. Then, return to standing upright, and then slowly to the left side.
