Maybe I just can't get over... what happened that day back in November.
Y'know, where I got gangraped at a circus by midget strongmen. I mean, it wasn't the most eventful thing in my day, but it made the list.
That video makes some very valid points about how much cooler martial arts uniforms look if you shorten the sleeves and have different colors for the pants and jacket.
If you wanna train in something to look cool just learn to play the guitar or something, at least you'll get more tail that way.
aight.. tricking and parkour has like 8 ground moves which is very hard to master.
that's why very few does it because it is hard to start with.
this is what you do.
1) google parkour/tricking+your location
2) if there is a meat up or something go there and your hooked up.
3) if not try to find these basic techniques and train them but stay safe.
4) stay safe ;P
To be boring and, you know, actually answer the question. These guys are obviously skilled and probably could (with specific training) adapt such skill levels to 'real' fighting however the video appears not to be intended to demonstrate anything other than athleticism and gracefulness.
If it takes your fancy then Taekwondo would be your bet or if the gymnastics appeal Parkour may be more to your liking.
