All of the following are considered a good, balanced position for a rider EXCEPT:

The concept of a good, balanced position for a rider emphasizes alignment and body posture that allows for effective communication with the horse while maintaining stability and comfort. A rider should sit in such a way that their body is aligned properly to achieve balance and support effective riding.

Sitting in the middle of the seat bones is crucial as it provides a stable foundation for the rider, allowing them to pivot and maintain balance as needed. Similarly, having the feet and legs positioned under the body ensures that the rider's center of gravity is balanced, which is essential for controlling the horse. Furthermore, keeping the arms beside the ribs allows for better flexibility and responsiveness, facilitating effective rein communication with the horse.

In contrast, having a round back disrupts this alignment. A rounded back can lead to a collapse of the spine, resulting in reduced support and balance. It does not promote the optimal position for stability or control, which is why it is not considered a good or balanced position for a rider. Maintaining a straight, aligned back is essential for effective riding, as it helps distribute the rider's weight evenly and allows for smoother communication with the horse.
