Former UFC Champion and WWE superstar Ronda Rousey looked unrecognisable in her latest public outing.

The UFC Hall of Famer appeared on the YouTube channel ‘The Diary of a CEO’ to discuss her troubled journey from her childhood all the way to UFC and WWE stardom.

The 37-year-old sat down with presenter Steven Bartlett for a tell all interview about her past from losing her dad at a young age to suicide and suffering two miscarriages with her current partner.

Her decision to speak so openly and honest about her legendary MMA career, health struggles and abuse suffered as a child comes in light of her recent memoir titled ‘Our Fight’ which details all of her past struggles.

Her memoir which took her two years to write details the American’s struggles with bulimia, depression and suicidal thoughts as she also reveals how she suffered horrifying abuse as a child.

In the tell all interview Rousey opens up to host Bartlett explaining how her difficult life journey started when she was just eight-years-old when her father took his own life.

‘My dad passed when I was eight. I didn’t know but he had broken his back in a sledding accident when we’d first moved to North Dakota and he had a rare blood disorder where he couldn’t heal from it.

‘He had been receiving diagnoses basically saying he would become a paraplegic and then a quadriplegic and could eventually die.

‘We didn’t know that he was going through this or dealing with chronic pain or anything like that.

‘He ended up taking his life when I was eight… My whole world turned upside down.’

She continues to detail the further pain she suffered both from other people and she inflicted on herself.

Rousey opened up about her struggle with bulimia as she developed the eating disorder at 16 because she was constantly teased for her masculine, muscular physique.

She opened up to Bartlett about how she would sometimes force herself to get sick after meals.

‘I remember the first time I did it. I had a childhood coach or something who took me out one day and he basically forced me to have a chocolate shake.

‘He was like, “NNo you have to have a chocolate shake come on, it’s fine, you train all the time, you need to relax, you have a chocolate shake.”

‘I felt so guilty about the chocolate shake and I had to make weight that weekend – there was no way I would be able to make it.

‘I made myself throw up the chocolate shake and it was cold, it didn’t hurt, it wasn’t that bad…

‘I thought it was a one time thing but the next time I like ate too much and I felt really guilty about it, it just became the panic button… I felt like it was the only thing I could do.’

She continued: ‘You have all this outside pressure to be able to maintain the same weight even though as an athlete you’re growing and putting on muscle and even getting taller so it was kind of like fighting nature.’

The former UFC champion also opened up about the harsh and abusive training regimes she would have to follow as a young athlete.

Going on to reveal that she couldn’t think of a single coach she had a ‘great relationship with’.

She shockingly went on to admit that her very first coach ended up dislocating her jaw as a child.

‘My first coach literally dislocated my jaw. I was a little kid, I threw him once in front of everybody and and laughed because I thought it was awesome.

‘He threw me on the benches on top of the table at everybody else’s feet in front of all these people.

‘Big Jim had grabbed me by the throat before to drive his point home that women can’t defend themselves. This is behaviour that I have been conditioned to tolerate since I was a little girl.
