You could prob. drop 8-10 pounds in a week on a hardcore cut, but then it will level of.....15-20 is realistic at your size........you'd be fing miserable though.
i think the first 20 should be not that hard but the last 10 would be the hard part. IT can be done. I have cut 10lbs in 2 days for wrestling before. So i know weight like that can be but at last minute. Just expect to pack alot of h2o weight back on again after the physical
I would think you can do it if you are very strict about your diet and workout routine. I dropped 20lbs in a month Nov. to Dec 2004 but again I was very strict. Took in 1500 cal a day, lots of protein , weight trained 3 days a week and cardio 2 days a week (I am a lazy ass and would rather cut cals than spend 7 days a week doing cardio). At that time I did not use anything but fish oil pills and vitamins, however, now I have kicked it up a notch with some clen. Good luck man you have a hell of a goal but I think you can do it.
