Fitness guru Bob Harper says he had a heart attack this month.

The 51-year-old Biggest Loser host told TMZ he was left unconscious for two days after having a heart attack during a workout in New York.

Harper was at a gym two weeks ago when he collapsed and was taken to the hospital. He was hospitalized for eight days and has yet to be cleared by doctors to fly home to Los Angeles.

Paxton currently stars on the CBS drama 'Training Day.' He previously starred on the HBO series 'Big Love' and movies 'Alien,' 'Titanic,' 'Twister,' and 'Apollo 13.'

The Biggest Loser host said he is improving but limited to non-strenuous exercise like walking for the moment. He said his family has a history of heart attacks, including his mom, who died from the condition.

Harper has yet to address his health scare on social media, but alluded to the incident last week on Instagram. He posted a photo of a candle and called himself "lucky" in the caption.

"My word of the day... LUCKY," he wrote.
