Honestly the best thing to do would be to work on it on the lungeline. Sometimes you think you're slowing your seat but really you're being thrown around up there.
Allow her to trot only if it's a nice rhythm. If it gets too fast, shorten the lungeline to make a smaller circle. Once she's fine again give her more line.
Remember that horses do not speak English. They learn from consistency. If you are allowing her to trot like a loon, she thinks that is acceptable.
Adding poles a stride apart will help her to learn to balance herself. Start at a walk, work up to a trot.
Remember, a nice big circle (lot of line that IS NOT dragging no the ground) when she gets it right. When she is too fast, shorten the line till she slow down, then feed it out again.
Assigning vocal cues to speed up (cluck) or slow down (easy) will help to make it easier for her to tell what you are looking for.
Now if you aren't interested in lunging, you can apply the same principal under saddle. Start with a large circle and slowly spiral to a smaller circle. If she slows down, make the circle bigger. You can also do this with serpentines (making them tighter when she is too fast, versus wider and more loopy when she is at a good rate. You can also do this with figure eights.
Be sure it is not just your hands riding her, but more your seat and leg. Tighten your core to restrict movement as you sit deep to add resistance.. don't just yank back on the reins (a huge no no anyway)
Change it up. Don't just drill circles, or she won't learn anything.
