Flatwork for hunters and jumpers should be short and efficient--20 minutes per day when you only do flatwork, and 10 minutes on days when you are preparing to jump. Don't work more than five minutes at a time on the flat without taking a short break--about a minute or two--to let the horse stretch and relax. A regular schedule for jumping includes one day a week in which you jump a course, and one day in which you either practice over gymnastics or jump single lines of fences. Also, if possible, take the horse into the woods or fields for a hack at least once a week. Make every second count while you're mounted. Avoid trotting or cantering around and around the arena without changing direction or performing transitions frequently. This type of mindless wear-and-tear on the horse will break the animal down both mentally and physically.
