Former Chicago Bear William “The Refrigerator” Perry claims to be in much better health after suffering a relapse of Guillain-Barre syndrome two years ago.

Perry, who says he was barely walking as recently as this January, says he is able to run at times now and is working out regularly.

“I was coming back really slowly, but it’s picking up and I’m getting around, back out in the world instead of locked up in the house,” Perry said as he signed autographs for fans at McCormick Place Convention Center in Chicago. Perry, at times, still uses a motorized scooter to get around, but the fact that he’s walking more often is major progress.
