I love the Biggest Loser. It's a serious problem; I've downloaded all the seasons.
Anyways, all that to get to the "last chance workout". I do some form of cardio 5 days a week, with weight training about 3 days a weeks in conjunction with this workout courtesy of the biggest loser and this chick's blog.
I did it this morning and I am dead right now.
My Quirky Life • Biggest Loser Last Chance Workout Routine
I really like CrossFit routines. Really short routines, but they will kick your ass.
