Ive always said I clearly dont climb correctly because I use geared bikes and still stand a lot. Im convinced its largely due to growing up and riding BMX bikes- its ingrained and what feels best for me, even if data were collected and showed I would be more efficient/effective/faster if I just sat the whole time.
I helped run a teen mentorship program for years where we rode 3x/week for 5 mo, did multiple campouts, then spent the last week of the program riding across the state as part of a huge annual ride- RAGBRAI. These kids would end the 5mo with 1500-2000mi, and many came to the program with little riding experience or even none at all. I constantly told the newer kids to not look towards me for how to ride and to just trust what I was saying instead. All the new bikes that were donated were entry level 3x7 hybrids and we spent multiple months just constantly reminding new riders to sit and shift instead of struggling up hills. Meanwhile, I would stand to climb most hills because I absolutely loathe sitting and slowly climbing.

I am not countering your comment, to be clear. How I ride is probably quite inefficient, especially when compared to actual pros who have extensive data and rely on it to gain any slight advantage they can. I would love to train my brain to enjoy sitting on climbs!
