For 2015’s sci-fi movie Ant-Man, Paul Rudd gained noticeable muscles on his body parts like chest, arms, and legs. Also, he shrunk his waist and dropped significant amount of body fat.

Rudd was able to adopt the body shape with lots of “flips and rolls.” He also gave up alcohol and carbs for a year.

Back in 2012, Paul bulked up for the romance comedy This is 40.

But his transformation for Ant-Man was the actor’s toughest body transformation so far. Brendan Johnston from CrossFit BMF devised a workout routine for the actor. Talking about Rudd, he said, “From strict diet, to supplementation, to working out at 5 a.m. He never complained. He only worked.”
