My favorite is her newest one Get Extremely Ripped 1000. I just did it today for the 1st time in awhile. It's a great workout! It's on the long side compared to her other workouts, but I burn a ton of calories with it and my muscles feel thoroughly worked.
I also like Ripped 1000 and Ripped and Chiseled. Really, I like all of them, except Get Extremely Ripped. That's the only one I've traded.
