What does the term "ascended" refer to in horse training?

In horse training, the term "ascended" specifically refers to a horse's ability to lift and engage its hindquarters while maintaining balance. This aspect of training is crucial for developing the horse’s overall performance, particularly in disciplines that require collection and precise movements, such as dressage and jumping. Engaging the hindquarters helps the horse to not only maintain better balance and rhythm but also improves its ability to carry weight effectively, resulting in enhanced performance and agility. Maintaining this balance is essential for the horse to respond correctly to aids from the rider, leading to a more harmonious partnership and greater effectiveness in various equestrian tasks.
