I don't remember the name of the video, but there was a workout on my OnDemand that was all standing or sitting ab exercises. Go to www.exercisetv.tv
and search there to see if you can find it - I think the instructor was Cindy Whitmarsh? I'll also look when I get home and see if it is still OnDemand and will edit with the name. I think it was 8-10 minutes long.
