Melissa - Slim and Lean is my 2nd favorite Jari Work out. My fave is Ripped to the Core. I did Jari Love for months before doing Cathe on a regular basis. Jari is different in that she has you do lower weights and higher reps. Mixing Cathe and Jari will definitely be good for muscle confusion.
DISCLAIMER: I am not worthy to speak of Cathe or Jari since I have been a slug for the past several days. ;-)
For those of you who live near a store called "Ross Dress for Less", check their DVD section. I often see Jari Love DVDs for 4.99 there. Her first DVD "Get Ripped" is not her best. The set is very dark, but her other DVDs are good.
