Vanessa Hudgens was one of many bikini-clad actresses to grace the screen in the new movie 'Spring Breakers' (alongside Selena Gomez and Ashley Benson) -- and if you're going to work in a bikini, you want to be comfortable in it.

Her favorite exercise routines include spinning classes and Soul Cycle, although sometimes she works a little too hard. So hard, in fact, that she injures herself.

"When I first started going, I was there twice a day. I close my eyes and bang my head to the music and wake up the next morning with a sore neck, feeling like I’ve been to a rock concert. It’s really good therapy," the actress admitted.

As an added bonus, wearing a bikini in 'Spring Breakers' gave her plenty of practice for wearing tiny outfits and looking silly at Coachella.
