I do that exercise (holding in my abs) every time pass a mirror.

I have been working pretty hard at the abs with crunches and I always tighten that TA (long word) in before I do each crunch. Is that correct?

So do you hold your abs in all the time once you're good at it?

I don't leak when I pick stuff up, only when I sneak and don't have a chance to "clench" ...

My back has not hurt since Knot taught me the trick. Even yesterday when I woke up with back pain from lying on my tummy, I was able to get rid of most of it with the exercise. I am SO happy....
