Myth # 1: To have rock-hard abs, you must do abs workouts every day.

Truth: Abs must have rest for recovery. Actually your abs muscles build only during the rest period. "3 to 5 days per week of steady, dedicated abs training should reward you with strong and sleek abs," says K. Kaehler, a professional trainer who authored Kathy Kaehler's Celebrity Workouts.

Myth # 2: Abs workout must take at least half an hour.

Truth: If it's taking you that much time to feel your abs working, you're not doing things right, says Kaehler. She was training Jennifer Aniston around 3 three days every week, and she didn't do any more than 5 minutes of abs every time. So check the form. Avoid using momentum and try to focus more on quality instead of quantity.

Myth # 3: You get stronger with super-slow crunches.

Truth: Taking too much time for each crunch - say, a minute - can by no means improve your strength... at least it doesn't leave you better off than the impacts of regular crunches do. Rather, ultra-slow abs work can prove less effective. Your workout must help you in doing everything better than before... be it kickboxing or picking up your suitcase. Funny though, you don't do any of those in slo-mo!

Myth: You get most of your ab workout when you do it at the end.

Truth: It makes zero physiological difference which time you pick for training your abs. What really matters is whether you're doing it consistently, says veteran abs researcher, physical therapist G. Willett, who holds an M.S. and working as an associate professor at the University of Nebraska Medical Center. The most suitable time to do some abs work is simply when you're used to doing it.

But if you're doing abs workout at the start of your routine workout, you got to get some warm up first. This gets your blood moving, which prevents lots of injuries that people encounter in their workout, says Willet.

Myth: Doing Pilates won't get you six-pack.

Truth: Pilates works out your core, so practicing it on a regular basis and combining it with apt diet plan and cardio, it'll hopefully give the six-pack you want, says K. Lyons, a professional personal trainer based in L.A. Still, Pilates doesn't guarantee six-pack either. The shapes of your abs is very much tied with your genetic properties, the leanness of your body, the length of your torso is and most importantly - your height, says Lyons.
