It’s safe to say it took Kate Hudson much longer than 10 days to achieve her rock-solid abs.

The How to Lose a Guy in 10 Days star showed off her toned tummy while enjoying a Pilates workout on the beach during her luxurious Hawaiian getaway.

In a video shared to her Instagram Oct. 16, Hudson shared moments from her weekend celebrating pal Jennifer Meyer’s wedding to billionaire Geoff Ogunlesi on the island of Lanai, including a clip where the Running Point actress proved she doesn’t need a gym to get in a good workout.

Indeed, the 47-year-old—donning a red-hot bandeau bikini and sunglasses—could be seen getting her sweat on as she did a few sit-ups on her towel while lounging with friends by the ocean.

But that was just part of the pre-wedding festivities. After all, Hudson also included a close-up of her vibrant wedding guest look, which was composed of a shimmering gold gown and statement jewelry.

As for her wedding date, Hudson was joined by her fiancé Danny Fujikawa, who accompanied her to the extravagant ceremony wearing a classic black tuxedo.
