He’s putting the flexing into Flexen.
Mets pitcher Chris Flexen arrived at spring training this year 30 pounds lighter than last season, and more chiseled than ever.
The 24-year-old — who is currently playing for the Amazin’s Triple A club in Syracuse — credits his body transformation to consuming smaller portions and hitting the gym for an hour, four days a week.
“The weight I was at wasn’t sustainable for an athlete,” Flexen tells The Post of his 260 pounds, which he began to shed after having surgery on his knee last August.
