MIKE TYSON has revealed how he was left too tired to go to the gym due to “having so much s3x” despite being in PRISON during the early 90s.

And the 53-year-old former boxing heavyweight champion also outlined how his lavish lifestyle cost him a huge amount of the personal fortune he amassed during his legendary career.

Iron Mike has been in the headlines over recent weeks as he ramps up the work ahead of his return to the ring.

The icon has been linked with a trilogy fight against Evander Holyfield, while Shannon Briggs has also claimed he has agreed an exhibition clash with Tyson for charity.

The Baddest Man On The Planet seems to be getting challenged from fighters all over the globe, but he says fans will be shocked when he finally announces who his opponent will be.

He continues to whip his supporters into frenzy by regularly sharing clips showing his stunning physique while training – but back when he was serving time behind bars he was getting a workout of a very different kind.

Speaking in his autobiography, he admitted he was still bedding numerous women on a regular basis even when he was in jail for a rape conviction.

Tyson said: “I was having so much s3x that I was too tired to even go to the gym and work out. I’d just stay in my cell all day.”

On his Hotboxin’ podcast, he continued: “You can’t f*** girls like you used to when you were young.

“You can’t be having bitches around like you do when you were young. They f*** up money, I didn’t know that.

“They were fun then, but when you’re older they ain’t fun no more. F***ing all day ain’t fun no more, you want some f***ing money, you know what I mean.”

Tyson retired from the ring in 2005 but filed for bankruptcy two years earlier despite earning over $300 million during his career.

Explaining where his money went, he added: “Giving people money like f*** everybody, party with everybody and f*** their mothers, their sisters and their cousins… orgies. I was crazy.

“I was so sick and I had no idea I was so sick. I bought a lot of cars for girls too.

“I was out of control drinking, gorging on food, f***ing women.”
