In recent years the sport of mixed martial arts, and the UFC in particular, have grown to be extremely popular worldwide. Alongside the mainstream popularity of athletes like Ronda Rousey, it's now becoming more and more common for people of all ages to train in martial arts programs inspired by the workout routines of the pros.

That of course even extends to the famous, and these seven celebrities prove that MMA training can be for anyone!

7. Demi Lovato

Demi Lovato is not a name you'd normally associate with fighting skills, but recently, she's really taken to martial arts. She seems pretty serious about her MMA training too, working out with professional fighters like Cung Le and Rashad Evans.

6. Kevin James

Kevin James might be known for playing a lovable loser in a lot of his movies, but Here Comes The Boom was created out of a genuine passion for the UFC and mixed martial arts. Not only is he a fan, but he trained with guys like Wanderlei Silva, Mark Munoz and Randy Couture to prepare for that role. He's kept up with it since, and is currently a student of MMA legend Bas Rutten.

In a little bit of extra trivia, James actually attended high school with pro wrestler Mick Foley. Both of them tried out for the school's wrestling program. Mick Foley made junior varsity. Kevin James, on the other hand, made the varsity team!

5. Freddie Prinze Jr.

The former teen heartthrob is a big fan of the UFC, and he's not just a casual viewer. He's a certified blue belt in Brazilian jiu-jitsu at the Gracie Academy, and currently trains MMA and boxing at American Gym in Costa Mesa, California. He also spent a few years working for WWE as a producer and director.

His whole family is pretty martial arts-centric to boot. His wife Sarah Michelle Gellar is a black belt in Karate, and the pair have even gotten his daughter Charlotte into jiu-jitsu as well. Don't mess with that household!

4. Frank Grillo

Frank Grillo obviously loves fighting. In addition to his recent role in the Captain America movies as Crossbones, he's acted in Warrior and currently stars in the MMA TV show Kingdom.

It's definitely not just for show though. Off screen, Frank Grillo is a certified badass. He was an avid wrestler when he was younger, and is an old-school Brazilian jiu-jitsu practitioner, having trained with Rickson Gracie and the Machado brothers. He's also an avid boxer, and has been training consistently for over 30 years!

3. Jason David Frank

Jason David Frank is probably best-known for playing the Green Ranger on Power Rangers. Somewhat less known though is his second career in professional fighting!

Frank fought four times as an amateur MMA fighter, winning each one in the first round. He then made his pro debut in 2010, defeating his opponent in just 46 seconds. He hasn't fought since due to some medical issues, but has expressed an interest in facing CM Punk now that the former WWE Superstar is in the UFC.

2. Rob McElhenney

It was pretty random seeing Mac from It's Always Sunny pop up on UFC fighter Donald "Cowboy" Cerrone's Instagram page, but Rob McElhenney is actually a pretty avid fan of the sport. He's also a black belt in taekwondo, practiced judo and wrestling as a kid. He now trains in mixed martial arts (which explains his new friendship with Donald Cerrone!).

1. Josh Herdman

Josh Herdman was an aspiring actor who managed to land a pretty huge first role as Gregory Goyle in the Harry Potter adaptation. He continued to appear in those movies for another decade, before deciding he wasn't content with just being a wizard.

For his next challenge, Herdman turned to the sport mixed martial arts, training full-time with aspirations of becoming a professional fighter. He might just make that dream come true, after winning his first fight in April 2016.
