I have only done 2 classes during last week, but I agree it will get abs back into shape over time.  I have plenty of time (I hope), so 6-12 months would be fine. I'm doing the weights and cardio at the gym too - not to mention the dredded crunches. But as we are learning on TOOLS if i stay focussed on what i'm doing the abs will appear in their own good time. They certainly have a better chance than if I had never joined TOOLS....
