Longtime trainer and current "Biggest Loser" host Bob Harper has reportedly suffered a heart attack.
The cardiac event took place two weeks ago when Harper was at the gym in New York City, according to TMZ, which just broke the story. He was left unconscious for two days and hospitalized for eight.
Harper, 51, is reportedly still in NYC, as he has not been cleared to fly to Los Angeles, where he lives.
Harper started as a trainer on "The Biggest Loser" in 2004, when the showed premiered. He took over as host in 2015.
The fitness expert told TMZ that the heart attack is genetics, since his mother died from one.
