Vee, since you like Weights that much, you should definitely get Split Sessions... I'm just sayin'.
Weights was the only one I had, but I got the two new ones and love them both!
Also, I am learning the Lauren love. I never have to modify in Weights (except just to use lower weights than Kelly), but I modified a couple moves in TLC to take out some of the impact and I thought Lauren was great. She modifies with gusto and looks like she is having fun, not like she "got stuck with the stupid modifier role" the way some backgrounders look.
