Whether you're a fitness enthusiast, a beginning gym-goer or someone in between, you should know that Pinterest isn't just a social network with lots of pretty travel pictures and cupcake recipes. It's also home to a TON of amazing fitness content. You'll find everything from workouts to inspirational quotes to fascinating health articles. To get you started, here are five of our favorite fitness Pinterest boards and why you should check them out. (And don't forget about our own fitness Pinterest boards, with everything from our favorite exercises to some behind-the-scenes looks at our company.)
