As the title says.. to me it seems that even gaining 5 pds in 1 day is a lot but some boxers a lot actually in fact gain atleast close to 10.. some 15!! To me this seems like this may be even harder than all the training and dedication involved in getting ready for the fight etc.. Does anyone know methods involved in dehydrating? no fluid intake for a week? no food for a week? how long does the dehydration begin beforehand? an hour in the sauna everyday? just a lot of running? anyone know for sure how its done?
