Danica McKellar is working on her fitness goals thanks to the expert herself, longtime workout guru, Denise Austin.

“I’m 51 and I workout so I can look like Denise Austin when I grow up,” the Wonder Years star, 51, captioned a video of her doing a fitness routine. McKellar also elaborated on how social media has been a source of “fitness motivation from those who seem to defy traditionally perceived age limitations,” and specifically called out Austin, Full House star Candace Cameron Bure, who regularly shares her fitness journey on social media, and fitness coach Denise Kirtley.

“I don’t lift heavy like some of them do, but I hope I can be motivating for some of you as well,” McKellar, who showed off her fit figure in a black crop top with matching leggings in the video, continued. “Remember: fitness is 80% clean eating, 20% exercise – I’m pretty sure at any age.

While the post’s comments section was filled with support, it drew the attention of Austin, who couldn’t help but gush.

“OMG!!! YOU are such a SWEETHEART!!!” she wrote. “Thank you for this Danica!!! And you look AMAZING!!!! This means a lot to me especially coming from you!!!!!!”

Bure, who’s McKellar’s industry peer through their work on the Great American Family Network, commented “Get it” with a muscle emoji. Kirtley also commented that she’s “honored to be mentioned!” and also said the actress looks “amazing.”

Fans also couldn’t help but comment about how great McKellar looks.

“You look oh so fit strong beautiful and stunning,” one said.

“You’re always looking great Danica!” said another.

“Well. Merry Shredmas to all of us,” another wrote as a nod to McKellar’s regular roles in holiday TV movies.

This isn’t the first time where the longtime actress has addressed aging gracefully. In fact, she regularly broaches the topic on social media.

In an Instagram reel from last week, McKellar shared a reaction as to how it feels “when people tell me I look the same as I did on the The Wonder Years.”

“I’m well aware that I don’t look the same as 35 years ago; that would be weird,” she said.
