Jay Cutler used to do this to prepare for the Arnold Classic, I'm contemplating it myself. I have 7 wks to the show, actually 6 because I really dont count the last week because I stop training and start the carb up process. I got on the scale tonight and I'm 222lbs w/ clothes on. I think I'm within shooting range for the light heavies but it's not going to come easy. I've started about 30mcg/day of T-3(along w/ my cycle) and it seems to be working very well as I've dropped about 3 lbs since last weekend. So now I think I'll sleep for 4 hrs, wake up and hit cardio out of a dead sleep(I have a treadmill here), then go back to bed for another 3 or 4hrs, then another session PWO the next day. So probably around 1 hr and 40 min-2 hrs of cardio/day. I cant do much cardio every 3rd day because of my 24 hr work shift(fire dept.) but I really think that this will help the rest of the weight fall off. I'm thinking if I can just come in at 198 lbs then I'll have a good shot at the overall.
