Heavyweight boxing legend Mike Tyson has explained his gruelling training regime as he bids to return to the ring and says he is still feeling weird after using stem-cell therapy.

The 53-year-old showed off his incredible, age-defying speed and power in training footage he uploaded to Instagram last week, declaring he was back and ready to take part in exhibition fights for charity.

Iron Mike has already been inundated with potential challengers to fight, with old heavyweight rival Evander Holyfield posting his own video in response to Tyson and opening the door to a potential third fight between the pair.

Joe Rogan recently suggested that Tysons incredible speed and power was not down to natural hard work alone, and now the veteran boxer has revealed the extreme lengths he is going to in order to get back in shape.

Speaking on the Rock the Bells Radio show on SiriusXM, Tyson was asked by rapper LL Cool J how he would get in peak shape in just six to eight weeks and replied: 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. Youre gonna make sure youre eating the right food.

For me its almost like slave food. Doing what you hate to do but doing it like its nothing. Getting up when you dont want to get up. Thats what it is. Its becoming a slave to life.

People think a slave to life is just enjoying drugs and living your 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. Thats when youre at your best.

Probed further on the mental aspect of preparing for a fight, Tyson continued: My mind wouldnt belong to me. 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 Id be in the best shape Ive ever dreamed of being in. As a matter of fact, Im going through that process right now. And you know what else I did, I did stem-cell research.

After LL Cool J asked if that meant Tysons white blood cells had been spun and then put back in, Tyson continued: 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 Ive been weird ever since, Ive got to get balanced now.

Tyson first revealed that he had undergone stem cell treatment which is usually used to treat or prevent a disease or condition in an Instagram live chat with Shaquille ONeal earlier this month.

You know what I had done? I had stem cell therapy, said Iron Mike. I feel like a different person but I cant comprehend why I feel this way. Its really wild what scientists can do.
