Alex Leapai has kept his arsenal under wraps but world heavyweight boxing champion Wladimir Klitschko hid nothing before outlining his chilling "dominate and terminate" philosophy.
Ukrainian Klitschko and his underdog Australian challenger Leapai delivered vastly contrasting workouts on Wednesday at a shopping centre in Obehausen, just a few hundred metres from this weekend's world title fight venue.
Leapai pecked away at the pads of trainer Noel Thornberry during a brief session which offered the many onlookers few clues about his style and tactics.
Klitschko went through an extensive session, moving fluently around the ring and pounding the pads of trainer Johnathon Banks with a succession of heavy shots.
"I know that a lot of boxers and their trainers believe that you cannot show what you're capable of and you are probably going to affect the performance in the ring if your opponent is going to see how you move and what kind of shape you are," Klitschko said.
"I have nothing to hide."
"I'm not going to show them my tricks, I'm saving that for the night," Leapai said.
"They (the Klitschko camp) came late, so they missed out on the goods bits, but I'm not going to show them everything.
"Dad was actually telling me to let them go and I said 'Dad, I'm not going to let them know my tactics, the world will see on Saturday night."
A defiant Leapai said he was used to being the underdog.
"On the night it all comes down to who wants it the most and I'm telling you, I'm going to beat this guy," he said.
"He's got to rip my heart out to beat me on Saturday."
Klitschko looked momentarily perplexed when he was told of that statement.
"I'm beating up people for a living, I'm not going to eat Alex's heart," Klitschko said.
"He can keep it for himself, his family, his children.
"But I will take care of my business and I know exactly what to do and what not to do.
"The experience that you gain through the years, you cannot buy in a shop. You have to get it.
"For the world title you have to prepare for a long time and of course for a challenger too.
"I'm not feeling that I'm better than than any of my opponents but of course I'm relying on my experience and I do things that are important to perform better and show your skills and dominate and terminate my opponents."
At least a couple of thousand people watched some part of the workouts, providing Leapai with a larger than normal audience.
"I think there's more people here than a lot of the fights that I've been to and a lot of the fights I've fought in," Leapai said.
