MIKE TYSON has been doing the rounds to physically prepare for his sensational boxing comeback aged 54.
Tyson, who retired in 2005, has a whole new diet and cardio regime as well as going through a “weird” stem cell treatment.
The former heavyweight king announced plans to make a return to the ring to compete in exhibition bouts for charity, and has been training hard ahead of his comeback.
He is set to face fellow legend Roy Jones Jr on November 28.
Speaking to rapper LL Cool J on the Rock the Bells Radio show on SiriusXM, Tyson explained the methods he is using to get back into fighting shape, as he revealed: “Really I would just change my diet and just do cardio work.
“Cardio has to start, you have to have your endurance to go and do the process of training.
“So something to do is get in cardio, I would try and get two hours of cardio a day, make sure you get that stuff in. You’re gonna make sure you’re eating the right food.
“For me it’s almost like slave food. Doing what you hate to do but doing it like it’s nothing. Getting up when you don’t want to get up.
“That’s what it is. It’s becoming a slave to life.
“Being a slave to life means being the best person you can be, being the best you can possibly be, and when you are at the best you can possibly be is when you no longer exist and nobody talks about you. That’s when you’re at your best.”
Tyson’s return to training for the first time in 15 years has been aided by stem-cell research therapy, that has left him feeling like a “different person”.
Stem-cell therapy is the use of stem cells to treat or prevent a disease or condition that usually takes the form of a bone marrow transplantation.
Tyson was asked whether that meant if his white blood had been spun and then put back in, to which he replied: “Yes. As they took the blood it was red and when it came back it was almost transfluid (sic).
“I could almost see through the blood, and then they injected it in me.
“And I’ve been weird ever since, I’ve got to get balanced now.”
Having previously claimed he feels in the best shape of his life, Tyson revealed he will be ready and raring to fight again.
He said: “My mind would belong to somebody that disliked me enough to break my soul, and I would give them my mind for that period of time.
“Six weeks of this and I’d be in the best shape I’ve ever dreamed of being in. As a matter of fact, I’m going through that process right now. And you know what else I did, I did stem-cell research.”
During his reign as champion, Tyson would wake up at 4.30am to run before later heading to the gym where he would do 10-12 rounds of boxing mixed in with an array of muscles exercises.
His diet consisted of 3000-4000 calories of carbohydrates and proteins which helped fuel his training sessions.
Tyson, still the youngest heavyweight champion of all time at 20, retired with a record of 50-6-2 and remains one of the most celebrated punchers of all time.
