Now that the Met Gala has come and gone, all eyes are turning to the Cannes Film Festival, set to kick off on May 11 in the south of France. And just like with any other big event, the stars are stepping up their fitness routines in preparation, especially Doutzen Kroes.

The model took to Instagram today to share a snippet of her workout routine, and it looks intense, to say the least. In the pic, Kroes shows off her incredibly toned physique in a sports bra and leggings while punching a punching bag, her rock-hard abs on full display.

Boxing has become a go-to workout for tons of top models, including Adriana Lima (see her latest boxing 'gram here) and Gigi Hadid. And while the workouts can definitely be difficult, these ladies' bods are testament to the fact that it definitely pays off. Excuse us while we sign up for a class, ASAP.
