When you work out, do you ever imagine that you're a superhero, and you have to get in shape so you can save the world? Or maybe you are a superhero, but can't say because of your secret identity. It's okay -- we won't tell.

Whether or not saving the world has ever been your inspiration, you'll be sure to get a great workout with these four "Superhero Exercises," courtesy of Men's Health and MSN. For example, you won't just do pull-ups -- you'll do "Spider-man Pull-ups." And forget squat leaps -- you're going to be doing "Hulk Leaps."

The names might inspire you, or they might make you laugh, but either way, check it out -- you might learn a new move that could save the day (or at least vary your workout)!
