WBC, IBF and WBA Middleweight Champion Claressa Shields is following in the footsteps of Muhammad Ali ahead of her superfight against WBO title-holder Christina Hammer on Saturday 13th April in Atlantic City, live on BoxNation.
She has moved her training base to Miami’s Fifth Street gym, which Ali used for many of his fights, for arguably the biggest women’s boxing match ever.
Shields, 24, has arrived at the world famous gym after five weeks at the US Olympic Training Center in Colorado.
"We've been going twice a day every day except Sunday for five-straight weeks," said the 24-year-old. "We put in lots of rounds sparring, tons of sprinting, pad work, push-ups, crunches and drills to help with my head movement.
"I've put my body through so much on this camp, and now it's time to start cutting it down a bit. I'm in great shape and my weight is on point. I'm also in a great place mentally and very happy with this camp overall," she added.
Shields has won all eight professional fights and captured World Titles at two different weights after being the first ever American boxer to win back-to-back Olympic gold medals.
Many pundits expect Shields to become the greatest female boxer ever, but Hammer is a serious threat.
The German has won all 28 professional bouts and will be competing in her 17th World Title fight at the world famous Boardwalk Hall.
Shields has been trained by former World Champion John David Jackson for her last two fights, and as she enters the finals days of training before the undisputed Middleweight Title showdown, Shields warned: "I know what I can and will do on April 13.
"I already told Christina I'm going to beat her and mess her up. I'm taking this fight 100 per-cent seriously. I'm going to go out there and dominate her.
"I don't want these belts handed to me. I'm coming to win every round on April 13. I'm a different kind of animal and Christina is going to see that on fight night. I'm ready. That's it."
