Ivanka Trump has shared a glimpse inside her opulent private gym while showcasing her envious physique during a workout at her $24 million Miami mansion. The 43-year-old mom-of-three took to Instagram to share a mirror selfie taken inside her modern exercise room, flashing her toned abs while modeling a white sports bra and blue athletic shorts. Ivanka—who recently opened up about her decision not to join her father Donald Trump’s new administration in favor of remaining in Miami—added in the caption of the photo that she is “feeling stronger and more motivated” now that a new month has begun.
