The 22 Jump Street star has been keeping up his slim physique since he was last spotted in March stepping out of the gym.
The actor's weight has fluctuated from role to role, dramatically slimming down for his role in the 2011 film Moneyball. He later regained it back and packed on the pounds, gaining 40 for 2016's War Dogs.
Last year, during an interview with Jimmy Fallon on The Tonight Show, Hill revealed that he asked his 21 Jump Street co-star, Channing Tatum, about how to slim down.
"I called Channing Tatum, and I was like, 'Hey, if I eat less, and go to a trainer, will I get in good shape?' And he's like, 'Yeah, you dumb motherf**ker, of course you will,'" Hill shared.
