“Friends” star Courteney Cox takes her exercise routine very seriously.

In an Instagram video posted on Monday, the actress, who celebrated her 60th birthday in June, shared her commitment to staying fit as she ages, while also humorously poking fun at her workout routine.

“I just had a birthday. Don’t love the number, but look, we have no choice. You just gotta do the best you can,” she said at the start of the post.

Cox gave fans an inside look at her workout routine, which included running on a treadmill, pull-ups, squats, and crunches. For this part of the video, she wore a black sports bra and leggings, with her hair up in a ponytail.

Later in the video, the “Cougar Town” star emerged from a freezer wearing a black bikini, a sheet face mask, and a baseball cap with what appeared to be red lights in it.

“What? It’s cryotherapy?” she joked as she walked off-camera.

Her celebrity friends flooded the comments section with compliments.

Mira Sorvino wrote, “You look amazing and continue to delight with your antics.”

Angie Harmon added, “WHAT?? WHO? WHHAAAAT??? KILLING IT GORGEOUS WOMAN!! HAPPY BIRTHDAY!!”

This isn’t the first time Cox has shared that cryotherapy and ice baths are part of her workout routine. In February, the actress posted a video of herself preparing to enter an ice bath in a blue bikini and wetsuit socks.

“Is this cheating?” she asked her fans while pointing to her socks, “because your feet get really f—ing cold.”

In a November 2023 interview with Glamour, the “Scream” actress emphasized the importance of hydration and her commitment to keeping her skin hydrated, regardless of whether the trend is called “flooding,” “slugging,” or “slagging.”

“I thought I would never do a cold plunge. I thought I would hate it, but I love it so much,” she shared. “I feel great for hours afterward. So, as much as you dread getting in, you know that you’re going to feel so good … the dopamine hit you get from it lasts a long time. Do it. Really, it’s worth it.”

Recently, the actress marked the 20th anniversary of the final episode of “Friends” with an emotional tribute on Instagram.

She posted a video of the final scene from the series finale, writing, “I don’t know how we were able to act through all the tears,” and added that she is “forever grateful” for the experience. The final scene depicted the group of friends gathered in Monica’s apartment one last time as they helped her move out.

The show also starred Jennifer Aniston, Matt LeBlanc, Lisa Kudrow, David Schwimmer and Matthew Perry. Perry died in October 2023 from “acute effects of ketamine,” according to an autopsy released by the Los Angeles medical examiner’s office.
