John Stamos is feeling "healthy" and "grateful" after spending 30 days in rehab to "take care of some things," according to a tweet from the actor.

Stamos, 51, posted a picture of himself in workout gear taking swings at a speed punching bag on Friday, with the clear message that he's back and feeling better than ever.

In June, the Full House star was pulled over for erratic driving and was later arrested on a DUI charge. He checked into rehab shortly after.

Stamos has insisted his rehab stint was little more than a check-in to make sure he's ready to take on his latest projects: He's reprising his role as Uncle Jesse on Netflix's Full House reboot Fuller House, and is also starring on the new Fox comedy Grandfathered this fall.
