Oh but you absolutely must try it! I assume being in the zone mentally is a familiar thing to you, so you really ought to try the physical equivalent!
A lot of people feel this way, but the reality is that we already do almost everything without conscious control, we just don’t tend to notice.
Not to mention the majority of the systems in our body are also beyond conscious control, and for many, beyond awareness completely (e.g. the nervous system).
The book “Flow” is a really interesting read, and describes how one’s approach to daily life can lead to something closer to that athlete’s state.
This is closer than most people realize.
It's reaching for the green button and hitting the red one instead. It's driving to the store near your office and ending up driving to your office instead. It's forgetting to drop your kid off at daycare.
I'll never be one of those athletes who lets go of conscious control and runs off muscle memory, but I've really enjoyed learning enough about my body that I can use it the way it was designed. It feels good when you go from "some part of me is always hurting" to "every step I take recruits muscles from foot and ankle to upper back because I learned how to use all of them against gravity".
