TMZ was on hand to capture the action, and they released a gorgeous photo of Herrig sprawled out in nothing but black panties and combat sports gloves.
"I'll be on @tmzlive @TMZ today at 1:45 at the @BellatorMMA open workouts !! Keep an eye out :)," Herrig tweeted.
Herrig, 28, is known for her sex appeal and wild antics. She makes no apologies for being girly and using her good looks to enhance her career.
“In female sports especially it’s about how marketable you are and I’m not going to hide who I am,” Herrig said.
Herrig said she feels for Olympic star Lolo Jones, a fellow female athlete who received backlash from teammates after using sex appeal to gain popularity.
"Lolo Jones, I feel bad for her," Herrig said during a recent appearance on The Jeff Probst Show. "My heart goes out to her a little bit because her teammates were so mean to her because she was pretty. It's like you can't tell what the media is going to grab onto."
Herrig explained that something clicked with her as a young girl when she heard that Anna Kournikova made a lot more money than the top-ranked female tennis player at the time.
"I don't do it just because I'm sexing it up," Herrig noted. "That's not my main goal. I'm a woman. I love being a woman. I love putting on pretty dresses and going out. But actually when I was in sixth-grade, I remember I was reading an article in the newspaper and it was about two female tennis stars."
Herrig explained that the article she saw featured one of the top-ranked girls, and the other she remembered as Kournikova, a mid-level contender who happened to be attractive.
"In female sports, it's about how marketable you are," Herrig said. "I'm not going to hide who I am."
“Society is a certain way,” Herrig told Probst. “If you know it, you’d be dumb not to go with it, ride it a little bit. Ride the wave.”
No word yet on when Herrig plans to return to the Bellator cage.
