WBA/IBF/WBO/IBO heavyweight champion Wladimir Klitschko (60-3, 52 KOs), was in his usual “working hard” mood during today’s open workout in Moscow’s DR Loder Fitness Club before Saturday’s sold-out title defense against unbeaten Alexander Povetkin (26-0, 18 KOs). More than 200 members of the media arrived to cover the open training and to hear both fighters with their respective teams assure everybody that they’re ready to beat the other guy. HBO will broadcast Klitschko-Povetkin live at 3:30 PM EST and rebroadcast fight the same night as a co-feature of Cotto-Rodriguez event on 9:45 PM EST.
