It’s a bird! It’s a plane! It’s a shirtless picture of Henry Cavill!

Less than 24 hours after Zac Efron gave fans two tickets to the gun show via his Instagram account, one of Hollywood’s other famously buff actors took it a step further by sharing a shirtless picture of himself Friday. “Warm up phase for Superman training started today!” he wrote in the caption. “Posting this pic to set myself a minimum goal…and force myself to actually keep going haha!” Cavill, who reprises his role as Clark Kent/Superman in Batman v Superman: Dawn of Justice, made sure to tag his personal trainer, Timothy Michael Blevins, in the Instagram photo caption.

Cavill hasn’t always been so confident in his own skin.

In the September 2015 issue of Men’s Fitness, for example, Cavill revealed that he was bullied during his time a student at England’s Stowe School. “They used to call me Fat Cavill,” the actor, 32, recalled to the magazine. “I actually had rolls of fat on me. One guy told me I had tits. I was a big eater, and I still love food. I’m still an indulger, in alcohol, in food, in all this things I enjoy in life. I’ve never been able to do things in half measure. That’s probably why I was a fat kid.”

No one would dare to call Cavill fat these days. In fact, to prep for his role in 2013’s Man of Steel, he got in the best shape of his life. “The mass build part was the fun part,” he said. “You get to eat a lot, and you’re lifting heavy weights. You feel really good because you’ve got big numbers going on the plates. But you’re always aware that you’ll have to eat less and start breathing more in order to show the muscles and the striations. It creeps up on you. That’s the less fun part.”

When he’s not playing the DC Comics superhero, however, Cavill’s fitness routine is less regimented. “When I need to do it, I’ll do it,” he said. “But otherwise I’m going to enjoy my life.”
