How often should I train with my trainer?
If you have the opportunity, I think twice a week is ideal, maybe even three. However, I believe that you must have a few sessions without your trainer as well to learn to think and feel yourself.
What is a good weekly training plan?
Very individual depending on the horse. I try to “train dressage” on the arena with an older horse about four days a week, various exercises.
Two days a week I activate with other things depending on the horse. Such as hacks, long lining, cavaletti or whatever may be needed to provide physical and mental variety. One day rest, but it’s always important for the horses to move: large enough paddocks, otherwise complement with walking the horse. Younger horses of course have fewer sessions per week. The 4-year-olds are ridden about four days a week in total and then often half of those sessions are out in nature.
