I believe this theory I was told in the amatuers to take 15 days off before a fight.To tell ya the truth I had sex the night before one of my fight's and to me it felt like I was stuck in the mud.My legs were completely gone by the beginning of the 2nd round.As a result it was my only loss.A professional fighters take somewhere around a month.I've heard the great George Foreman say he would take 72 -78 days of no sexin' before his big fights.But for someone like John Conteh he said it was no big deal for him.He would sleep with woman and party to the early hours of the AM before his fight's.
