It looks like Geraldo Rivera started a trend in Hollywood.
On Tuesday, Hugh Jackman tweeted "If the bar ain't bending, then you're just pretendin #xmen #daysoffuturepast." "The Wolverine" star attached a photo of himself straining as he lifted what appears to be very heavy weights, his face red and veins and muscles on his arm visible.
We have to give him credit - the weights are pretty high off the ground.
And he's is not the only one showing off a workout selfie.
Although Nick Jonas claims he is not one for shirtless photos, he tweeted and posted to Instagram just that, along with the caption: "I never do this but... Healthy living and fitness update. Post workout picture. #diabeticinshape #2.0."
We wonder which male celebrity will be the next one to show off some skin after hitting the gym.
