Bob Harper celebrated a huge milestone in his recovery since suffering a heart attack earlier this year.

The 51-year-old “Biggest Loser” host recently completed cardiac rehab.

“Yesterday was a BIG DAY in my recovery from my heart attack. I finished my cardiac rehab,” Harper captioned an Instagram photo on Thursday.

Harper suffered a heart attack on Feb. 12 at New York City’s BRICK gym.

Harper attributed his survival to the two doctors that happened to be in the gym at the time of his heart attack.
