Always try to have a goal or purpose for your "training" sessions. It can be as simple as working on flexing or improving your horse's peformance trotting over logs. There has to be something you would like to either learn or improve upon. How are your transitions? Is your horse flexible and does she give to the bit? How is her collection? You can even split up your riding time by working on different things during your hour of riding. For example, warm her up for 10 - 15 minutes, work on improving her flexibility for 15 minutes, add some interesting patterns and maybe some logs to keep her mind thinking and increase your control for another 15 minutes, then finish with the flexing again (if that is what you wanted to accomplish). Planning out your riding sessions in advance will help keep you and your horse interested and progressing.
