Whoa...100 Workout!!

Okay, so have any of you been crazy enough to try the "100 workout"?
I found out about it on Tumblr and I decided to try it tonight because I've been looking for a workout that fits into my specific needs.  Basically I'll give you the general idea:

100 Workout:

100 Jumping Jacks

90 Crunches

80 Squats

70 Leg Lifts

60 Jumping Jacks

50 Crunches

40 Squats

30 Leg Lifts

20 Jumping Jacks

10 Minute Run

Okay... so if THAT isn't insane, I don't know what is.  All of those workouts raise your heart rate significantly.  Guess how far I made it tonight?  Not very far.  I made it to 100 Jumping Jacks, 90 Crunches, 80 Squats, and I think 30 Leg Lifts.  Oh my god, I was DYING.  *Come on now, cut me some slack, I had surgery only a month ago*
Moving along.. I'm going to try and do this again tomorrow night and see how far I get and I will update you.  I won't be updating every day since this is not a workout/fitness blog, hahah.  But comment and let me know if any of you have been NUTS enough to do this!!!  I don't know if I'll ever get all the way through!
<3 Goodnight
