Parkour is a physical and demanding sport. Not just on you and your body, but the structures that you practice on. If you're thinking of building your own Parkour gym equipment, you need to be prepared to build something that will be able to handle the type of abuse it will go through. Pushing, pulling, swinging, jumping, each puts a tremendous amount of stress on a structure and you want to be sure that your Parkour equipment can handle it.
