I would like to be able to do gallop training too, but due to our location (Colorado) and the weather (snow stays on the ground for 1-2 weeks after it falls, and then everything is mud for another week, and then it turns very solid and hard), training outside is not really an option until around the end of May. We have a large indoor arena (a little smaller than a football field) with good footing, so that is where we ride in the winter.
I am trying to get her into shape for a 3'6" show season, which will be our first season jumping over 3'3". She needs to be in excellent shape. I'm looking for some ideas where to start and how to progress.
We have some rear-end balance issues that we need to work on, so any suggestions would be greatly appreciated. We have jumping lessons once a week, and I do not want to jump her any more than that.
About the horse: Gracie is a 10 year old Thoroughbred mare. She has good legs and I'd like to keep them that way. She can be headstrong sometimes, and is bored easily. Variety is a must.
Anything will help :) Thanks bunches!
