Philbin called "Live With Regis and Kelly" on Monday to say he'd been "through the wars" in his recovery but was building up strength by walking and lifting light weights.
He joked that when he returns to the show, he won't be the "fun-loving Reej" that he was before because his entire personality had changed.
The last time Philbin, 75, called the show, he complained about not having sex for 3 1/2 months. Co-host Kelly Ripa asked Monday if that had improved. Philbin joked that it was up to "five times a week."
