If there's one thing that the Tracy Anderson Studio in Studio City will do to you, it's make you sweat!
Nobody knows that more than Kirsten Dunst, apparently, because she is absolutely soaked! Luckily, she's being smart about it though — instead of getting dehydrated and grumpy, she's hydrating like a boss!
Hydration is key when you're putting in that much effort to your body!
Lookin' fab, Kirsten! Keep up the hard work!
