All Bases Covered Except Abs

hey guys, I’m going through CW’s TBT and it’s working great, I just thought I’d add in some weighted ab exercises since I have the time to do it. I have DB’s, stability balls, a russian chair, and that’s it. I’ve looked at the ab workout thread for atheltes and babehounds, however, if doing most of these exercises weighted, how should I split them? What could the rep scheme be?

pick one or two each day. dont kill the abs any given day that hampers the next w/o to much no matter what lifting day it is stimulate them. Vary the reps and loads go heavy one day high rep another etc. Much like any other Body part.

sweet, thanks!
