Training camp already started last week for the Green Bay Packers, but Aaron Rodgers is still in Montreal, Canada supporting his girlfriend who is training for her role as Psylocke in "X-Men: Apocalypse."

In an Instagram post she shared four days ago, Olivia Munn showed off her Taekwondo skills and quick reflexes as she kicked the mitt being waved by a female trainer.

In the background, Aaron Rodgers can be seen also punching a mitt with his male trainer.

But the ace quarterback is not known for his boxing skills and not a few fans called Aaron Rodgers out, with one writing, "The guys in the background look off."

Another said, "Terrible awful punching by that guy in the background. As a black belt in uechi ryu and tang so do and a black shirt in Kung fu he is incredibly sloppy."

They were gushing about Olivia Munn's skills, however, as they think that she's perfect as Psylocke in "X-Men: Apocalypse."

One fan wrote, "Damn that's amazing, no Ronda Rousey but I think she can give her a run for her money."

Another said, "You rock Olivia! Great To see your commitement To the role! You look great as Betsy and is making us Psylocke fans really happy! Good luck!"

Olivia Munn is really dedicated to her workout routines, as she credits boyfriend Aaron Rodgers for inspiring her.

In a piece by Good Housekeeping magazine, "X-Men: Apocalypse" star Olivia Munn said that Green Bay Packers quarterback Aaron Rodgers continues to inspire her to live healthier.

"Aaron is different than every other man I've ever met ... there's so much I could say. Everything a good person can be, he is," Olivia Munn said of her boyfriend.

"He's in such great shape, and especially lately, he's been eating so well and working out. Having somebody in your life like that is so motivating."
