Jason Momoa
Age: 46
Surprisingly, Aquaman isn’t into hitting the gym to maintain his build — instead he prefers outdoor activities, like boxing, mountain climbing, and surfing. “It’s very hard sometimes to just work out. It’s monotonous and you can get stuck in a rut,” he told Men’s Health UK.
Chris Pratt
Age: 46
After landing roles in Jurassic World and Guardians of the Galaxy, Chris Pratt transformed his build. The actor now follows a grueling workout routine, but the majority of his weight loss was the result of cutting out junk food and alcohol. “I probably lost about 35lb in six weeks. I ran five or six miles a day. I ate leafy green salads and protein shakes. I cut out all alcohol. Trim, trim, trim,” Pratt told Men’s Health UK.
Kevin Hart
Age: 46
Kevin Hart is known as one of Hollywood’s hardest working comedians — and that includes in the gym. The actor, who also works out with his frequent costar Dwayne Johnson, prioritizes cardio, weight, and core work to keep his proportions in check, and makes sure to fit his workouts in even when he travels.
John Krasinski
Age: 46
It took landing a series of action roles — 13 Hours and Jack Ryan — for John Krasinski to bulk up and leave his The Office image behind. The actor says working out has benefits beyond the physical. “If I didn’t work out a few times a week, I would start to overanalyze. It definitely takes me out of myself for a minute. And it gives me my best ideas. Your brain definitely works better when it’s all lubed up with endorphins and sweat and blood,” he told Men’s Health.
Sam Heughan
These celebrities demonstrate that staying in shape after 40 is less about any single method and more about consistency — whether that means outdoor adventures, disciplined gym sessions, or finding the mental motivation to keep showing up.
