Mine all like to work and will meet you at the gate when they see you coming. Does not matter how much I work them. However I change up what I do when I ride....
I also never work on the same thing 2 times in a row. If I work on turns one day I will work on rollbacks the next time. Some days I just lope the whole time. Some times I will do nothing but walk and let them stand. I have yet to have a arena sour horses or a barn or buddy sour horse.
