Q: How can I stop my lower leg from swinging when I ride?
A: You are not going to like this answer!! The best way to improve your leg position and keep it still is to make sure that you do lots of work without stirrups. The more work you can do without the support of stirrups, the greater control you will have over your leg position. It is also advised that you check your stirrups are the right length for you. Again, one of the best ways to do this is to practice riding with no stirrups in your flatwork and then make sure your stirrups are the right length when you take them back. Ideally, you want the bottom of the stirrup iron to be at your ankle when your leg is hanging loosely. You can also check this with your instructor.
