OK! This is called the lazy vault. There are alot of vaults in Le Parkour. This moves is the most easy moves and this is the first move that I've learn when I first started doing vaults. Now Im going to explain to you all how to do it in steps. But remember, safety first and when you get the hang of it, practice, practice and practice...

Here are the steps:

1. Steps
   

• Find a rail about groin height that is firm and won't budge.
  
• Run up the rail at 45 degrees and place the hand nearest the rail on it.
  
• Swing the leg nearest the rail up and over.
  
• Let your other leg follow through.
  
• Once both legs are over, place your other hand behind on the rail and use it to push off from the rail.
  
• Land smoothly then continue running.
  
  

2. Tips

• Practice , practice, practice! This trick is easy but you'd be surprised how easy it is to mess up.
  
• Look what you're vaulting over before you try this.... falling 30 feet isn't nice.
  
  3. Warnings
  
• Parkour and Free running are extreme sports. Do not attempt without proper training and perhaps consider visiting a gym for practice then move on up to the street.
  
• Keep your back hand down! If you don't you'll land facing a strange angle from the rail and trip.
