UFC Women’s Strawweight Champion Joanna Jędrzejczyk described her Muay Thai past, as well as her future in the fight game, in an interview with Submission Radio this week.

Some may be surprised to learn that the fighter sometimes called “Joanna Champion,” who earned the UFC title last June with a one-sided TKO victory over Carla Esparza, began her training to simply lose weight.

“I was sixteen,” she explained to Denis Shkuratov. “I wanted to be healthy, I wanted to lose some weight and I went for my first training [session]. In the beginning I didn’t know what Muay Thai meant. But, I liked it so much. After six months of training I had my first competition in Poland. I won, and after that I knew that I wanted to do it. ”

Shkuratov asked if the champ had a weight problem growing up, or just wanted to improve her appearance.

“I was like 10 kilos more heavy than now, ” Jędrzejczyk answered. “So I didn’t feel good, you know? I was at high school at that time; so I wanted to be a good looking girl.”

Jędrzejczyk would win several world titles in Muay Thai before making the switch to MMA. Last year, the opportunity came up to fight in the UFC at 115 lbs, but she wasn’t sure she could make the cut.

“Even 12 months ago I didn’t expect that I could make 115,” she explains. “I was trying, but I didn’t have a good dietician. But right before I signed the contract with the UFC, I got in contact with Jacob Mauricz. He’s one of the famous dieticians in Poland and probably soon he’s gonna be the most famous dietician in Europe. And I’m very happy. And now it’s very easy for me to make 115.”

Jędrzejczyk defends her title against Jessice Penne June 20 in Berlin.
