But it's been a long road to losing 60 pounds in six months.
Last July, Pratt posted a photo to his Instagram account showing off his dramatic weight loss and newfound six-pack.
How did he do it? "Six months no beer. #GOTG Kinda douchey to post this but my brother made me," Pratt wrote alongside the below photo.
In reality, the process of losing pounds was a bit tougher.
"Three or four hours a day of just consistent, ass-kicking hard work," the 35-year-old actor explained to Men's Fitness.
Pratt's workouts included P90X , running, swimming, boxing, kickboxing, and he even completed a triathlon.
With the help of a personal trainer and nutritionist, the actor increased his caloric intake to 4,000 calories a day and drank tons of water. "I was peeing all day long, every day. That part was a nightmare," Pratt told the magazine.
But the actor was happy to learn he could still eat on the intense weight loss program.
"I actually lost weight by eating more food, but eating the right food, eating healthy foods and so when I was done with the movie my body hadn't been in starvation mode," Pratt told People magazine. "It wasn't like I was triggered to just gorge myself and get really fat again."
Now, he says, "It's something that I think I can maintain because I don't spend four hours in the gym each day. I do maybe one hour in the gym maybe four days a week, and that's it."
Pratt joked to Vulture of his weight loss and gain for roles: "I just like to gain weight and lose weight. It's a rollercoaster. I just want to do this. I want to touch God."
Before beefing up, Pratt was most well known for playing the bumbling Andy on NBC's "Parks and Recreation." NBC/"Parks and Recreation"

"The first 20 pounds was sympathy weight because my wife was pregnant," Pratt explained to SheKnows. "I was gaining weight as she was gaining weight ... The other 35 pounds I did just by declaring that I was going to do it. And then my rule of thumb became: 'If it's there, eat it.' And then I would order two entrees at every meal. I would always have dessert, and I would drink the darkest beer on the menu."
To play a Navy Seal, Pratt told People he "was doing 500 push-ups a day, working out at the gym, running five miles a day, but with no food, and I tore my body apart ... I felt terrible afterwards, had to get shoulder surgery, and I wore myself down doing that because I didn't have the proper coaching."
At the film's premiere months later, Pratt told E! Online: "I was about 50 pounds or 40 pounds lighter than I am now. I worked out really hard and I cut out everything bad for me for a long time and I just focused on trying to become a believable Navy SEAL."
