I checked out a clip of the slim in 6.. looks challenging! You could probably do some of the resistance with your 3 pound weights for now. I have some resistance bands I bought from walmart along time ago, honestly I dont use them much :(
I personally love Kathy Smith! I lost my first 20 pounds using
her winning workout, and wieght loss workout. Lately I've been doing the standing abs workout and peel off the pounds pilates that you can view free on Hulu :) Insanity I think would kill me, haha! Tell us how you liked the slim in 6 if you try it.. I think you should and that you will suprise yourself :)
