Day 2 of get skinny for cruise

Today, I did this workout http://www.bodyrock.tv/2009/10/29/todays-workout-thursday-october-29-2009/

and I'm hoping to head to the gym in a few mins and get some cardio in, too. I only got through four sets. It took me 21:32. I'll try and get the last two in tonight before bed, but my legs are just wooped. Couldn't make it go on any further!!! LoL
