TRENTON, N.J. (AP) — New Jersey Gov. Chris Christie says undergoing gastric bypass surgery more than a year ago was a "life-changing decision."
Appearing on his monthly TownSquare Media radio show Wednesday night, Christie says he works out four days a week and has achieved better health.
The 51-year-old governor hasn't said how many pounds he's shed, but he has become noticeably thinner since secretly undergoing the surgery last February.
He says he enjoys riding a stationary bike but does not like doing side-lift exercises with dumbbells.
The possible 2016 Republican presidential candidate has said he's struggled with being overweight his entire adult life.
