Josh Brolin, 47, flashes his abs after working up a sweat at the gym with fiancée Kathryn Boyd

The couple that exercises together, stays together. 

That might not be the actual saying, but it certainly seems to be the case for Josh Brolin, who showed off his abs while leaving the gym with his fiancée Kathryn Boyd on Sunday.

The 47-year-old seemed to have coordinated his look with Kathryn, as they both sported red and black ensembles following their workout in Venice, California.

Josh sported a red tank top, which he could be seen pulling up to wipe the sweat off of his face, which revealed the actor's toned abs.

He coupled the top with a pair of black and red athletic shorts, finishing off the comfortable look with black and white Nike sneakers.

He covered his brown hair with a black and grey baseball cap on the outing, which he sported backwards.

Kathyn also wore a red tank top for the gym trip, which she coupled with a pair of form-fitting black leggings that showed off her toned pins.

She added a bit more color to her ensemble by sporting a pair of purple and light blue Nike sneakers.

Her windswept blonde tresses were styled straight, with a few wisps falling in front of her face as she walked.

She hid her eyes behind a pair of stylish, black sunglasses, and had a grey backpack strapped to her back.
