Gisele Bündchen got the kids out of the house for a workout -- hitting the gym in Miami as the supermodel and Tom Brady's marriage is seemingly all but over.
42-year-old Bündchen -- who was also spotted at the gym on Monday -- is focusing on her fitness as she remains in South Beach ... and on Tuesday, she brought Ben and Vivian along for the sweat session.
Gisele rocked a white tank and gray sweats for the workout -- and per usual, she was not wearing her wedding ring.
