This coming year will go by and be done before you even have a chance to realize it. There are so many things you can do, and you are very fortunate you have a trainer to work with to improve, get better and be a pro for the day you guys start jumping again.
I am going to be sending a new gelding in for training to do straight flat work because he probably won't be ready to start seeing jumps until at least the summer. Dressage and flat work IS the basic of any discipline and even once you start riding again, you will still be doing flatwork in between your jumping sessions.
Good for you for taking the time to do this. Both and your horse (and future horses)will benefit from it from the extra training.
