I’m not picturing that. Maybe it’s just a technique I don’t own. The change of direction for the arm would be slower for me than using the gathered body tension with the other arm.
Annnnd we're back to the original question. Is it that way because you don't practice it, or do you not practice it because that's how it is?
I think it's probably some of both. Humans being humans, things don't work exactly the same from one body to another. We train, and find certain movements that feel more natural to us. Odds are, especially early on, that we will practice those more. Later, we may make a conscious effort to practice the less natural movements, but will they ever feel as natural?
And that's ignoring the impact of time. There are certainly things which felt much more natural at 20 than 60.
