I watch the trainers I watched at demos pre Covid. Michael Peace, Richard Maxwell and Mark Rashid. There is now a charge for Rashid. I pay it but then forget to go to his site.
I have some DVDs too from my early days of riding. Pippa Funnell. Richard Davison.
I went to a couple of Dressage days on one of which Carl Hester and Davison discused their (different) ways of teaching and asking for a flying change.
I miss my dressage lessons but it is a dilemma. There were safety issues at my old RS. I currently share and hack the loveliest, safest, most comfortable mare but, like my Maisie, she does not do well with lateral work or the school.
