It's always weird gymdads who walk up to you and tell you "you're doing this completely wrong, stop doing it" but never tell you why. I'm convinced a lot of them don't even really know what is right or wrong, they just get an ego boost saying that. Like, cool, thanks for letting me know I'm doing it wrong, but, y'know, since you know the right way to do it, shouldn't you at least tell me what is wrong instead of just saying it is wrong?
That's why I was motivated to learn the proper way to do stuff, so that even if they come to me again, I can just explain them why they are wrong instead.
Whoah, guess it worked.
Feel blessed that I've never really had that experience. Any time someone's talked to me about my form, they've been chill and given me solid, understandable pointers.
This has actually happened to me once, but just once...
