in sprinting and in probably in most activities we try to identify like what are the non-negotiables what are the rules here like in squatting we know what the rules are right we don't want to bend to one side we don't want to overly Flex our our spine we don't want to anally rotate our shoulders we don't want to have knee valgus where our knees come in and touch each other we don't want to have super wide feet we don't want to have internally rotated feet when we're when we're squatting all of these things that we know that we don't do they govern the things that we can do
