Ben Affleck Looks Super Buff During Rehab Stint

Ben Affleck may or may not don the cowl again for another 'Batman' movie -- especially after heading back to rehab -- but based on how he looks right now ... dude totally could.

The actor was seen heading to a meeting Monday in L.A., and he was looking completely yoked in a fitted tee. Don't worry, this ain't just a good angle of Ben from the front ... he had a full-blown gun show on display from the side as well. It was sunny out, so ... ya know.

Looks like all that working out at his home gym a few weeks ago really paid off while he was attending rehab. Also worth noting -- we haven't really seen him without a jacket on for a minute now, including Sunday's outing with Jen Garner and the kids. Who knew?!

It's unclear if Ben has finished his treatment, but we have seen him out in public more regularly in recent weeks.

As for the Bruce Wayne thing -- sign him up.
