there are some links to tutorials on vaulting, if u have a single rail u can practice many differnt vaults. the easiest ones to get started on are probably lazy, monkey, gate, and speed. once u get good at these u can try doing things like monkey/kong to precision. (if u dont have a rail or something, go look around in the forest there are probably some fallen trees about waist high those should do, or u can make ur own things out of wooden boards)
