Florabelle - I'm not sure.  I follow the chart which is basically the same number of reps as the other exercises.  Have you tried adding weights to your ab exercises?  There's another thread where abs was discussed but I can't find it.

Hi Ladies.

This is a website I also got from one of the threads. Has exercises for every muscle group. Maybe it can help:

Here's another site

Also remember it's what you eat that helps your abs more than anything.
