Ready to sweat in black leggings and a white tank, Cameron Diaz
met baseball star boyfriend Alex Rodriguez
for a workout at Equinox South Beach on Tuesday. The lovebirds both hit the Stairmaster, burning calories for nearly an hour. Days before, they'd teamed up for a romantic dinner at Casa Tua in Miami Beach. "They were real low key and just wanted to be alone and talk," a source tells PEOPLE of their meal.
