Gwyneth Paltrow kicked off her vacation to Sardinia with a busy day on the water on Friday. She worked out on a treadmill on the deck of Steven Spielberg's "Seven Seas" yacht before Gwyneth Paltrow put on a bikini to enjoy the sun. Gwyneth drove a jet ski, hopped onto a floating trampoline with Moses, and went snorkeling and swimming with Apple during their getaway. Gwyneth and her kids were spotted enjoying their vacation with the Spielbergs over the weekend, and they hit the beach before taking a stroll through Porto Cervo on Saturday. Gwyneth has been showing off her impressive bikini body in multiple suits, and it's clear from her morning jog that she's serious about maintaining her fitness routine.
