The “FRIENDS” star appears in Smart Water’s new campaign, which captures her workout instructor adding a whole new exercise to her routine. In the comment section, fans could not help but praise her good form.

Aniston was sporting a black racerback-style bra with a dipping neckline and barely-there straps. She paired it with black high-waisted leggings and black-and-white sports shoes. Her hair was styled in loose waves, with the front half secured away from her face at the back of her head.

In the video, instructor Dani Coleman says, “All the way to the low abs,” and the actress does that. Then, Coleman instructs, “All the way back down to the four planks.” Right after Aniston goes into the position, the instructor says, “Pull sip.” The camera cuts to show her switching hands to take one sip from each of the two bottles of Smart Water.
