I know there's probably a million videos on this subject, but I'm still finding it hard to keep my feet in the right position with stirrups. I naturally tense up a decent amount while riding, specifically my whole leg area. I can fix it when my trainer tells me to but as soon as I get to a trot or even just after a couple minutes I just kind of loose it.

Does anyone have any resources or tips that worked for them to know how to rightly position? Thanks.
