Jennifer Lopez and Alex Rodriguez got steamy on a luxury yacht ... with some pull-ups, kettle bell swings and a full-on workout WHILE ON VACATION!!
J Lo and A-Rod were sailing off the Amalfi Coast and squeezed in an intense workout ... proving yet again there's no excuse ya can't bang out a workout sesh while on vacation. A-Rod got so sweaty ... he took off his shirt and showed off his Hall of Fame-worthy bod.
One great way to cool off ... a dip in the ocean, of course.
