im new to ba parkour and to parkour in general, and i was wondering aspect of parkour i should learn first. so far i can do simple two handed vaults.... and not tooo much else :P. i have a friend who is pretty good at parkour and he's been teaching me little by little when we have time but im worried that that won't be enough. please leave any questions comments or suggestions.
Well, since you live in the South bay, the best thing to do would be to drop by one of our jams sometime! We have Saturday and Sunday sessions every week and very much welcome beginners. As Puck said though, watch videos. There are tons of tutorial videos off Youtube. I got started off Urban Current's tutorial series, which I still think are the best tutorials I've seen thus far.
In terms of videos check out also Kaos progression series, which show ways to break down complicated movements in a more manageable subset of "baby-steps", allowing to progress in a controlled and successful way.
