I'm missing the correlation between parkour and golf. lol
I haven't personally done parkour, but I know it's one of those things that you almost definitely have to be taught. Maybe not every step of the way, but you better learn how to properly land, roll and tumble before you start branching out to do dangerous stuff. If you can't find an instructor, look for a gymnastics class. If you can get the safe landings out of it, the other parkour stuff is about timing, momentum, creativity and practice.
