Colin Donnellis showing off his impressive physique.

The actor, 40, posted twophotoson Instagram of him shirtless in the gym Wednesday, sharing an update on his fitness journey with his fans — and jokingly referring to his “#dadbod.”

“I’m not #becomingwolverineagain, primarily because I’ve never actually played Wolverine BUT I am enjoying putting in some* work and getting into probably the best shape of my life at 40 years old and, welp, I’m pretty proud ¯_(ツ)_/¯,” he wrote in the caption.

By “putting in some* work,” he noted, he actually meant he has put in “*a lot” of work to achieve the physique he’s now showing off.

“Don’t you dare delete this 😍,” his wife, Patti Murin, commented in response to him saying he was “probably gonna delete” the post.

She also reposted the photos on her Instagram Story, writing, “This is my husband 😍😍😍.”

Donnell also tagged several fitness accounts on the post, which he said “have been great follows and helped me along.”

Celebrity trainer Don Saladino– known fortraining Ryan Reynoldsand Blake Lively — was among the accounts theChicago Medactor tagged in the post.

In addition to his physical fitness achievements, Donnell has had a rather exciting month.

He and Murin, 42,welcomed their second daughter, Lorelai,on April 2, PEOPLE exclusively revealed.

“She is absolutely perfect 😍,” the parents said of their second child, the younger sister of 2-year-oldCecily Philips.

“I have a sister and we are very, very, very close, so I love the idea of the two of them having that bond,” Murin — whooriginated the role of Princess Anna in the Broadway adaptation ofFrozen, told PEOPLE in anexclusive pregnancy announcement in October. “Plus, there’s the whole Frozen thing which makes it extra special.”

Just weeks after her birth,their first child, Cecily, underwent open-heart surgeryto repair a hole in the organ she was born with. Ahead of welcoming their second, the parents — who wed in 2015 — said they “just try to live each day and hope for the best.”

“We certainly know what it’s like to face obstacles,” Donnell said at the time.

“There’s no planning,” Murin added. “What happened with Cecily was scary at first, but she’s literally jumping on the couch right now, she’s the poster child for open heart surgery. So you never know what’s going to happen. And all you have to do is stay present and not stress.”
