You have to understand something though...if a fighter gives himself 8-10 weeks to train....they can drop 20lbs easy in water weight....that brings him down to 170-175.....The he stops all the fatty food...starts eating stuff to bring up his metabolism...pump himself full of carbs..add daily workouts...we are talking 1-2lbs a day on top of that 2-4 wks he is at 160....he slows down on weight loss and sucking weight for a wk and just balances himself out so not to drain himself too much...last 2 wks drops 6-8lbs for the weigh ins...then after weigh in rehydrates back up another 5-6lbs....happens all the time...give or take the exact weight lost and how long it takes...but the general idea is there
