UFC Hall of Famer Randy Couture, who suffered a heart attack Wednesday, was discharged from the hospital Friday, telling ESPN that he's doing better.

Couture felt ill after working out Wednesday night and then walked himself to a local hospital, where he found out he had suffered a heart attack. He was in intensive care for a while but is expected to make a full recovery, Couture's lawyer, Sam Spira, said in a statement.

Couture also released a statement Friday thanking the medical staff.

"Thanks to all of you out there expressing your concern," he said. "Your love and support mean the world to me and my family. Live your lives to the fullest."

Spira said Couture walked home from the hospital.

"I walked into the hospital from home; I am walking home from the hospital," Spira said Couture had told him.

The 56-year-old Couture, considered one of the greatest MMA fighters of all time, retired in 2011 with a pro career of 19-11. A multiple-time UFC heavyweight champion and light heavyweight champion, Couture currently works as a color analyst for the Professional Fighters League on ESPN.

"On behalf of the PFL family, we wish our partner and friend Randy Couture a speedy recovery," PFL CEO Peter Murray said. "We're all in his corner and look forward to having him back in the booth."

Throughout his legendary career, Couture beat the likes of Chuck Liddell, Tito Ortiz, Vitor Belfort and Pedro Rizzo, among many others.

Since retiring from active competition, he has pursued an acting career, most notably appearing in "The Expendables" franchise.
