All of Tamilee Webb's "Quick Toning" tapes consist of three 15-minute toning workouts, each with its own warm-up/cool down; I particularly like the arms/abs combination. Tamilee is warm & upbeat.

This is a more challenging workout, but beginners using light weights should do fine. Two 20-minute workouts for upper/lower body plus a 7-minute abs section.

An even more slow-moving introduction to yoga. Provides detailed explanations of many basic yoga poses.

Pilates is another great way to get your abs in shape (without doing traditional crunches) by focusing on your entire midsection. Instructor Ana Caban provides helpful guidelines plus motivation.

Great to do if you don't have much time or as an add-on after other workouts, the three 10-minute programs on this tape really strengthen your abs with unique exercises.
