Holy muscles Batman!

Ben Affleck showed off the results of his daily workouts on his first night out of rehab with pals, and the actor looks drastically healthier than he did when he entered treatment a month ago. Gone are his man boobs and here to stay is his ripped physique!

The Oscar winner has been focusing on his fitness and sobriety lately, and it also looks like he's making some new clean-living friends.

"He has a specialized program to suit his needs — meetings, working out, reading, therapy. Everyone’s journey with addiction and treatment is different and built for the individual. [Affleck’s] is a good mix of mental and physical work. This is what was outlined by his doctors and team," a source dished to People.
