Jennifer Aniston Shows Off Toned Body in Motivational Fitness Video

Jennifer Aniston

Even incredibly toned celebrities with personal trainers experience a case of the Mondays when it comes to working out—just ask Jennifer Aniston.

On Monday, Feb. 26, the former Friends star took to Instagram to share a glimpse into her exercise regimen while promoting the fitness brand Pvolve. "If you’re having one of THOSE Mondays, I FEEL YOU ???? Just gotta do it!! ???????? @pvolve," she captioned the video.

In the clip, Aniston, 55, completed  mountain climbers on an exercise mat and held various poses while using a slant board. She finally groaned and collapsed on the floor while doing pushups.

"Oh god .... You know those days when you just don't wanna do it?" the actress said while lying on the ground. "You just gotta do it."

She then (begrudgingly) continued with her workout.

Meanwhile, others drew inspiration from The Morning Show actress. "I was having one of those Mondays, but I did it anyway bc you inspire meeee ??????," one person wrote.
