Sofia Vergara knows how to keep herself from skipping gym time!

The 42-year-old actress recently Instagrammed this hilarious shot of herself getting her exercise on with one very noticeable figure keeping watch -- a cutout of her super-buff fiance, Magic Mike XXL star Joe Manganiello, shirtless.

"Who wouldn't get motivated with that guy in the back staring at u like that hahahhha!!! #Idontwanttoworkout," she joked.

Judging by her selfie though, the Modern Family star has definitely not been slacking in the gym department. Leave it to Sofia to look hot while working up a sweat in a sports bra, and stretchy white high-waist pants that somehow look flattering on her.

ET recently talked to Sofia's trainer -- celeb trainer to the stars, Gunnar Peterson -- who dished on Sofia's less than perky attitude when it comes to exercising.

"Her favorite thing to do in the gym is leave," Peterson joked. "I think it's a sort of necessary evil. I don't think it's her favorite thing, and I know that because of the swear words that she uses bilingually."
