Alex Rodriguez isn't a pro athlete anymore, but don't tell his abs ... the legendary slugger shared a shredded shirtless photo, posing with his equally jacked girlfriend, and they look incredible!
48-year-old A-Rod and his fitness trainer boo Jac Cordeiro are on vacation in the Dominican Republic ... and the couple shared some snaps from the trip. Alex's daughter Ella is also on the vacay.
Rodriguez last played baseball in 2016 as third baseman for the New York Yankees, before hanging up his glove and leaving the sport as one of the most feared hitters ever.
