ChaLEAN Extreme Peeps?

Options
I am 4 days away from finishing my first round of Insanity!!! Down 10 pounds and 7.5 inches, but I have a long way to go!

I want to start lifting and was thinking of doing ChaLean Extreme (already have it, but haven't tried it). I was looking for people who have done it, results, motivation etc. I still have about 40 pounds to lose and will be doing strength and do Insanity on the cardio days. I think I want to progress to a Stronglift type program after, but I just bought powerblock dumbbells, so don't want to invest in any more weights at the moment.

So, thoughts on Chalean Extreme??
