Caveletti on the lunge 2-3 times a week? We have them out nearly every ride (only when I’m super super short on time is nothing in the arena), and once a week on the lunge. For the lunge, I make a row of trot poles, and a row of canter poles. Just by taking a step or two lets me alternate - allows for a really good fitness workout as well as teaching push.
And yes, jumping is really only once a week. If the BO has something set out I might pop over it a couple times to mix it up, but not what I would call a “jump set”
