You've probably heard most of the hyperbole on ab flattening—from how often you should train to how many reps you have to do. Here, our experts help separate ab facts from fiction.
myth Strength-training exercises like crunches will get rid of ab flab.
truth Spot training (or reducing) isn't possible. While crunches are important for firming and strengthening the abdominals, they won't remove fat from that area. In addition to ab exercises, do a total-body strength workout to boost your overall lean muscle mass, and blast fat and calories with a consistent cardio routine (at least 30 minutes, five days a week for weight loss). Don't forget to follow a healthy diet as well, and also realize that genetics plays a part in whether you have a round or flat belly.
