Craig Writes: Smooth Criminal by Alien Ant Farm has got to be one of the toughest chest songs in the BodyPump arsenal. It's four rounds of work, starting with a super-slow build that gradually works its way up to a pair of single sets. The first two rounds aren't bad, and you get a short break between each. But it's those last two rounds that are the killers - first, they shorten the build, and then extend the single sets. You know it's bad when the class (instructors included!) issues a collective "ughh!" as they finish the final rep, and then just lays there waiting for the world to stop spinning.
