Also yea pretty much what Ecchi said.
Freerunning/parkour is something better just fucking around with towards learning.
that's how i learnt doing it for the past 2 years.
however i did have a person help me out in the beginning giving me tips.
that's the only thing i recomend. Get friends with people that are better than you and get them to give you tips and pointers,
In my case i had Jisse help me out. I had real luck getting to become friends with him and he's the majour reason i can make replays today.
Get friends, fuck around and have fun.
that's my tips
