Abs are more than just the ripped six-pack look. Strong abs help the body perform faster, with more power. They help maintain better posture, resist fatigue, amplify the transfer of strength from the upper to the lower body and vice versa and they support the lower back and spine better. As the name suggests Target: Abs is a workout that targets the abs. You know what you need to do.
Extra Credit: Don't drop down while transitioning from plank to plank.
