ya i definately need to practive my rolls and landings. Got up on the school roof tonight and got some good gap jumps in. Plus the roof has like a rubbing coating which is very nice for landings. Once i get someone to tape for me and to keep a look out i will post more
please re-evaluate why you've decided to do parkour. if your answer has anything to do with thrill seeking or showing off, then i suggest you save yourself the trouble and learn something else. parkour has absolutely nothing to do with roof gaps and can be practiced completely at ground level. roof gaps should be completely avoided unless you have many years of experience or if you are legitimately caught in an emergency situation where jumping from one roof to another is unavoidable.
now if you are actually into parkour for the right reasons (self improvement mentally and physically, to help others, etc.), then practice the basic vaults and techniques, condition endlessly, study movement and the discipline itself, and repeat (when i say "repeat" i really mean it). if you aren't ready for a gradual progression over years of conditioning, training, and studying, then please stop before you hurt yourself or our reputation as traceurs.
thank you.
