I just want to understand one thing.
Why can't I just practice the physical discipline of getting from one point to another, past any manner of physical obstacles (leaving the rest of my life, metaphorical obstacles, etc. out of it), and learning to move or locomote my body through different surroundings using different methods than just the conventional methods of walking and running that are currently used by the modern world, regardless of time-urgency or purpose? Who says there isn't any mental element
at all (note emphasis) in such a practice?
If, according to the infinite wisdom of Dave Sedgeley, this isn't Parkour, or ADD, then what should we call this separate discipline? I'd be happy to accept a new name for it and settle this debate once and for all. I'm sure what I described in the paragraph above has the scope to be a discipline or a study in itself, even if it doesn't fit under the broad, philosophical purview of Parkour/ADD, and that the concept will also find takers and practitioners, and practical application. Then I can go about practicing my separate discipline and be happy with it, and Dave (and others, if they exist out there) can continue practicing whatever it is they do under the name of Parkour/ADD.
Yeh, this can be true...if your training is based almost completely on what is interesting, which i was under the impression that it isn't for you.
Way to go Caleb! You really got him there. He's trapped in his own words.

(now only if he would actually accept that he's trapped..., but that's just wistful thinking)
I strength trained long before i started parkour and have yet to be injured beyond minor things that can hardly be considered an injury.
Same here man.
People, typically, don't just start hitting massive things because they can make the distance. Because they still don't know what will happen even if they do make it. I've seen plenty of beginners that have huge jump, that could easily hit larger things than i could. But i haven't once seen a beginner take off and hit, say a 12 foot rail precision, just because they could make the distance easily. Because in their head they think, "i could slip, what if i land wrong, what if i don't make it, what if i jump too far. i don't know what will happen. That scares me. Thats dangerous. I need to work up to that by doing some smaller ones first". The only thing that separates them from me is that when i look at it i think "yeh i can make that, i expect to stick it first try, if i come up short ill bounce back, if i over shoot ill just hop off"
You're forgetting a huge aspect of parkour training, and in my opinion the most important aspect. Control. I came into parkour already very strong, but i didn't just go out and try to hit the most massive things i could, because i still had no idea what would happen because i had no control. So i trained control on small things constantly. I spend almost 100% of my day every day falling over and over again. I made it so that i could adapt to any situation, so that i could put my body in any position i wanted when i wanted to and when i needed to. The more control i had, the bigger things i could do. It never mattered how strong i was, what mattered is how much control i had. What mattered is whether or not i could look at something and go "yeh i can do this, and if any thing goes wrong i can adapt." Now i can do whatever i want because i have the control to do it. I know that if i don't hit it perfect i can adapt. I know what will happen in almost any situation that i end up in and that i will be able to adapt in each and every one of those situations and come out safely because i have the control to do so. This is why i haven't sustained any real injuries.
Word.
I think with a 2.x+ deadlift and squat for reps, 1.2x Bench and Bent-Rows for reps I could be considered a pretty strong guy. I can box jump 50 inches, broad jump 9 feet+. But according to Dave's impeccable logic, I should find smaller jumps boring to train then, shouldn't I? However, I would behoove him to come and look at my training approach and then say the same nonsense that strength leads to training beyond one's level. When I drill precisions, I never go beyond 6 feet (or 7 feet max), when I drill drops I never jump off 2 feet. And I don't go around seeking larger/longer jumps in my other training just because I'm strong enough to do them, most people (except impressionable teenagers, who just need direction and guidance from the right seniors) are smart enough to not try things beyond their (skill) abilities, even though they may have built a certain level of strength and physicality.
Just because i can go further doesn't mean that i will. It doesn't matter how far i can go if i cant control it when i get there.
