anybody doing Jillian's Biggest Winner "complete"?

I got the 5-video set on ebay a while back (5 videos shipped for $12, not bad!) and i just finished my 5-days of of doing the series ... i've noticed that a lot of people are doing Shred, am i the only one doing this set???

it was definately challenging for me! the cardio kickbox was relatively easy but those last 2 videos (the "maximize" ones) just killed me.
