I got this in a 4 pack of Jari Love DVDs. This was the first I tried. Pretty challenging. I was impressed. I liked how she calmly explained the moves...no yelling or cutsie stuff. There is a lot of back and forth between the cardio/step and weights which breaks up the workout. But the cardio segments felt a little short.I have been doing The Firm DVDs lately. This is significantly harder than those.I hope the rest of the DVDs in the pack are up to the same standards.
