Depends on the horse. My big horse gets lunged or schooled when ridden because he is such a meat axe to hac out, 4-5 times a week. Different areas though and I work on different things. The other horses get hacked out twice a week and schooled maybe 3 times. I do over fences work- depending on the ground conditions, maybe once a fortnight at the most, once they know how to jump there is no need to drill them at it.
