What is the main focus of the jump known as the oxer?

The oxer is a specific type of jump commonly encountered in show jumping that consists of two verticals set at an angle, requiring the horse to jump over both elements in one motion. The main focus of the oxer is indeed on developing the relationship and coordination between the horse and rider.

Executing an oxer effectively requires the rider to maintain proper balance, timing, and communication with the horse. As the oxer demands a combination of height and width, it challenges the rider to navigate their horse’s approach, adjust their position, and support their horse during the jump to achieve a successful clearance. This interaction fosters deeper understanding and connection between horse and rider, enhancing their overall performance in jumping events.

The other options, while they may relate to different aspects of jumping and training, do not capture the essence of the oxer's primary purpose in improving rider-horse coordination. Speed, jumping height, and basic training can be associated with various jumps, but the oxer's design specifically emphasizes the synergy and alignment required between the rider and the horse.
