How to Ride Your Centerline
Enter the arena with your eyes up on the judge at C. Ride with straight with more impulsion than you think you need, prepare for your halt at L with half halts and sink your heels and seat into a perfect square halt at X. The haunches will not drift to either side if you have enought impulsion and you are sitting balanced and straight on both seat bones, looking straight ahead. Imagine riding a bike very slowly down center line, it is diffuclut to balance, however, if you ride with more speed it is easier to stay balanced and straight.

However the key is your position, check it out and make sure you are correct.
