"Well I guess you all heard what happened," the fitness guru wrote on Instagram Monday alongside a photo of himself smiling and petting his dog Karl as he sits up on a hospital bed.
"Two weeks ago yesterday I had a heart attack. I am feeling better. Just taking it easy. KARL has been a great nurse. I want to thank everyone for the outpouring of messages and support," he continued.
"It feels good to be cared about. I've been home for 8 days now. Again, THANK YOU SO MUCH!! I'm lucky to have such good friends and family to take care of me right now," Harper concluded, confirming that he was back at home in Los Angeles despite reports that doctors had not cleared him to fly back.
Harper was reported to have been working out at a gym in New York two weeks ago when he suffered the heart attack that left him unconscious for two days.
A doctor on site was said to have administered CPR and used paddles to keep him alive.
The television host has stated that his family has a history of heart attacks including his mother who died from the condition.
Previously, Harper alluded to the health scare on Instagram by sharing a photo of a candle with the caption, "My word of the day...LUCKY."
Harper starred on "The Biggest Loser" as a trainer for 16 seasons before becoming host for Season 17 following Allison Sweeney's departure.
