the truth is that you cannot change your abs in 7 days. if someone promises you that it can be done they are lying. forming 6 pacs in abs takes months of dedicated hard work and commitment and cannot be attained in such a short span of time
Training your abs 3 times a week is the best choice for good results. If your abs are still sore you can still train, but be careful.
A minimum of 21 DAYS non stop if you are not Fat.
Every other day.

To get ripped abs in 30 days, a personal trainer in a gym can assist in making a plan to achieve the goal. There are exercise programs on the market that target the ab muscles. A diet high in protein and low in fats can also be beneficial.
"Abs in a minute" or any other seemingly impossible exercise claims, are just that, impossible. For "abs in a minute" try doing crunches or sit-ups every day for a few minutes and see if that will improve your midsection in a few days, weeks or months.
