On Saturday, Lori Loughlin took a break from promoting Fuller House and got her sweat on at her trainer's Body by Simone studio in LA. While there, the actress casually uploaded a photo of her insanely toned abs on Instagram, and from the looks of it, Aunt Becky's still got it! Along with the snap, Lori wrote, "Sweaty Saturday with @bodybysimone the best way to start the weekend. #simonedelarue #bbs." Just this week, Lori and the rest of the Fuller House cast shut it down at their big LA premiere, and that same night, they also made a surprise appearance on The Tonight Show Starring Jimmy Fallon. Take a second to marvel at Lori's enviable figure, above, and then check out who else is confirmed for the Full House reboot before it premieres on Feb. 26.
