Hi, just wanted to say that abs shouldn't be worked more than about 3 days a week. Normally about 2 days a week, with a couple of days in between. You don't want to build the muscle there, just strengthen and tone it, and you want to give your muscle time to repair itself. If you overdo it you can make your waist thicker. This is information from a trainer. Hope that helps a bit My lower tummy and hips are my problem area...and I wish I could just do crunches every day and lose that layer! But I guess if it were that easy, none of us would be here
