Freestyle running.

Honestly you have to start young. Have to admit he's pretty badass.

One battle he has to overcome is heights. Believe it or not some people are afraid of heights.

His natural sense of balance is superb. The only way I can describe this is like knowing your way up while underwater with your eyes closed. I can expand a lot on this subject.

Flipping or doing any form of gymnastic moves requires an explosive muscle type like fast twitch.

So you are using all that, and more, to run down a road or trail hoping rocks, fire hydrants, logs, and an occasional, "Fuck me, there's a dog in this yard!"

There is also a lot of mental mathematical crap involved like rate of drop over distance. Easy on the sauce on this one, your ass don't need to overshoot a set of doubles.

After a while it becomes second nature and its freedom.

Just don't fuck up, it hurts.
