Medical Reports: HEALTHCAST: Parkour

WSVN -- Runners vault, climb, jump, and wind their way along any landscape.

Robert Ray: "It builds our bodies. It helps us, you know, learn to move fluidly through our environment."

If it looks like something out of the movies, that's because it is.

Parkour was featured in the latest James Bond movie, and in last year's romantic drama "Breaking and Entering".

The sport was developed in France -- it's creators wanted a work out that didn't cost money.

It's influenced by martial arts, gymnastics and cardio exercises, and works the whole body.

Robert Ray: "With all the running, all the jumping."

Sean Bell: "The butt, the thighs, the calves -- everything in my lower body."

Some of the popular moves include: A monkey vault, underbar and wallrun.

With proper training, Parkour can give you a better understanding of your body...

Justice: "It's a great way to get in shape."

And also improve your balance.

Sean Bell: "It really comes down to who you are and what you want to do. What you want to achieve and what you find fun in this."

Parkour can be dangerous -- especially for beginners.

But once you get over the wall, it can be a physical and emotional outlet.

Robert Ray: "It gives me a chance to be free and express myself."

It helps these guys reconnect with their childhood -- but kids don't try this at home!

There typically are not Parkour classes at gyms; it's mostly groups of people training together.

You can find Parkour training sites and classes on the internet.
