This is one of my favorite DVDs from Cathe. I had it for about 2 years before I pulled it out and tried it - but when I did, I did Step Blast twice a week for two months, that's how much I loved it!! And Step, Pump, Jump is an awesome circuit workout too. I love the Hi/Lo portions of it.
I was afraid to try it because I read the reviews and it was considered more complicated in choreography, but it only took me two or three tries to get the moves down in Step Blast and SJP is very easy to learn. And the music is the BEST!! I love the entire Body Blast series and I would say this one is a definate must have.
